Sigma fp gets 4K raw output to Atomos and Blackmagic recorders in firmware 2.0

26 Jun

Sigma has released a major 2.0 firmware update for its fp camera that adds, amongst numerous other new features, the ability to record Apple ProRes Raw over HDMI when paired with an Atomos Ninja V monitor/recorder and Blackmagic Raw over HDMI with a Blackmagic Video Assist 12G.

When paired with an Atomos Ninja V updated with the latest firmware, the fp is able to record Apple ProRes RAW at up to DCI 4Kp24 or UHD 4Kp30 directly from the camera’s full-frame sensor. Additionally, this update will make the fp the first mirrorless camera in the world capable of recording Raw Full HD (1080p) video at 120 fps. Sigma doesn’t specify the exact framerates or resolutions that are possible when capturing Blackmagic Raw on Blackmagic’s Video Assist 12G recorder, but like the Atomos, it will require a firmware update.

Other new and improved features include cinemagraph creation and playblack, CinemaDNG footage playback, still capture during live view and movie shooting, still image capture from recorded footage, support for camera movement control with Zhiyun’s Weebill S gimbal and camera control support while in USB mode. Sigma also says the update adds ‘HDR in movie shooting,’ but it doesn’t divulge any specifications. We have contacted Sigma to request additional information on this front.

Sigma has also updated and improved upon existing functionality, including explicit stating of dual base ISOs (100 and 3200), improved autofocus performance, improved exposure metering accuracy and support for multiple CinemaDNG capture modes. An issue where flickering could appear in dark footage has also been corrected in the firmware update.

You can download firmware version 2.0 (previously version 1.02) from the Sigma fp support page.

Impressive sharpness: Sigma 14-24mm F2.8 DG DN Art sample gallery updated

22 Jun

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_1853735007″,”galleryId”:”1853735007″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

We initially got our hands on the Sony E-mount Sigma 14-24mm F2.8 while covering the launch in Japan last July. We’ve since acquired a copy here in Seattle and have been shooting with it around town (and in Cabo, pre-quarantine) primarily on a Sony a7R IV body (our initial samples were on an a7R III). These extra pixels should help convey just how ridiculously sharp this lens is. Have a look!

Sigma announces 100-400mm F5-6.3 for E-mount and L-mount, teleconverters and more

19 Jun

Sigma has announced the launch of its first ultra telephoto lens specifically for full-frame mirrorless cameras, as well as a pair of teleconverters, a new USB dock and a new mount options for three of its prime Contemporary lenses.

100–400mm F5–6.3 DG DN OS Contemporary

While this new lens might look similar to its previous 100-400mm lens, the 100-400mm F5-6.3 DG DN OS Contemporary has been designed ‘from the ground up for mirrorless camera systems.’ Specifically, the lens will be available in Sony E-mount and L-mount.

It’s designed to cover fulll-frame image sensors and is constructed of 22 elements in 16 groups including one low dispersion element (FLD) and four special low dispersion (SLD) elements. It uses a stepping motor for autofocus, has a nine-blade aperture diaphragm, a minimum aperture range of F22–29 and a 67mm front filter thread. At 100mm it has a minimum focusing distance of 112cm (44”) and at 400mm it has a minimum focusing distance of 160cm (63”). The lens measures in at 86mm (3.4”) diameter, 197mm (7.8”) long and weighs 1,135g (40oz).

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_1628781788″,”galleryId”:”1628781788″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Sigma 100-400mm F5-6.3 DG DN OS Contemporary is currently available to pre-order for Sony E-mount (Adorama, B&H) and L-mount (Adorama, B&H) for $ 950. The first units should start shipping on July 10.

Sigma Teleconverter TC-1411 and TC-2011

In addition to its mirrorless ultra-zoom, Sigma has also announced two new L-mount teleconverters: the TC-1411 (1.4x) and the TC-2011 (2x). Sigma says these two teleconverters are ‘Designed to complement Sigma’s renowned optical formulas’ and feature a dust- and splash-proof design ‘comparable to that of the Sigma Sports line lenses.’

The TC-1411 (1.4x) and TC-2011 (2x) are currently available to pre-order for $ 400 (Adorama, B&H) and $ 430 (Adorama, B&H), respectively, and should ship on July 10 alongside the 100-400mm F5-6.3 lens.

Sigma USB Dock UD-11

New lenses and teleconverters also mean new docks for updating firmware and adjusting settings. Sigma’s new USB Dock UD-11 models use a USB Type-C connection and are available for Sigma L-mount and Canon EF-M mount mirrorless lenses. As with Sigma’s other docks, the UD-11 models makes it possible to update firmware and customize settings on Sigma lenses with these mounts.

These EF-M and L-Mount docks are also available to pre-order starting today for $ 59 (Adorama, B&H) with an expected shipping date of July 10.

16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses

Sigma has also announced it’s made its three F1.4 mirrorless lenses available for L-mount camera systems. The 16mm, 30mm, and 56mm F1.4 DC DN Contemporary lenses are identical to their Sony E-mount, Canon EF-M mount and Micro Four Thirds predecessors, and are currently available to pre-order for $ 450 (Adorama, B&H), $ 340 (Adorama, B&H) and $ 480 (Adorama, B&H), respectively, with a July 10 shipping date.

It’s worth mentioning that the only current APS-C cameras that utilize the L-mount, and therefore would be most appropriate for this trio of lenses include Leica’s TL2 and CL mirrorless cameras released in 2017. But for full-frame L-mount users who primarily shoot video, these lenses do make for compact, affordable Super 35 lens options.

Sigma 24-70mm f/2.8 for Sony Review

18 Jun

The post Sigma 24-70mm f/2.8 for Sony Review appeared first on Digital Photography School. It was authored by Suzi Pratt.

sigma 24-70mm f/2.8 lens review

From the moment the Sigma 24-70mm f/2.8 DG DN Art lens for Sony was announced in December 2019, it’s been in hot demand. Fast forward to May 2020, and the lens is still back-ordered and difficult to get ahold of. It’s not hard to see why, as this lens is half the price of the Sony 24-70mm f2/.8 G Master. This Sigma 24-70mm f/2.8 for Sony review highlights some key specs of the new Sigma Art lens and contemplates why it’s such a sought after lens.

24-70mm: the desert island lens

Ask any photographer what single lens they would rather have if marooned on a desert island. I’ll bet a good chunk of the answers would be the “24-70mm.” This is a classic mid-range lens that covers a useful and versatile focal length. 24mm is just wide enough to capture vast landscapes without much distortion, while 70mm offers just the right amount of zoom to capture shots from a distance.

Most camera brands, including Sony, offer two versions of the 24-70mm: one at f/4, and another at f/2.8. The Sony 24-70mm f/4 is of fantastic quality at a semi-reasonable price point of $ 898.00. There are often used ones to be had for several hundreds of dollars cheaper. But the Sony 24-70mm f/2.8 stands at a whopping $ 2,198.00. See why there’s been a clamor for a half-price Sigma version?

Let’s not forget the Tamron 28-75mm f2.8, another lower-priced challenger at $ 879.00. This lens is a bit smaller and lighter than the Sigma version. It also has a smaller filter size of 67mm compared to the Sigma lens’ 82mm filter thread size. However, you sacrifice 4mm on the wide end, which may matter if you need maximum wilderness.

Back to the Sigma.

Build and construction

Sigma Art lenses are known for their superior bodies, and the 24-70mm f/2.8 is no exception. This lens was made in Japan, and it shows in the craftsmanship. It feels solid in the hands and is even a hair lighter than the Sony version. The lens has two rubber rings: one for focusing and another for zooming. There is also an Af/MF switch, a button for AF-Lock, and a locking mechanism.

The locking switch is a bit unusual. Enabling the lock prevents the lens from accidentally extending. On most lenses, the lock is rock solid. But on the Sigma, the lock can easily be overridden by simply twisting the zoom barrel. That makes it easier to run and gun shoot, but on the other hand, it’s a little too easy to accidentally unlock your lens in the field. I didn’t mind this feature, but some photographers may not like it.

The zoom is equipped with internal sealing against dust and moisture. There is also fluorine coating on the front of the lens to repel water and oil. Overall, this lens held up like a champ while shooting in a light rainstorm.

Image quality

Testing of the Sigma 24-70mm f/2.8 was done on a Sony a7riii. In terms of sharpness and overall image quality, the lens was fantastic in almost every way. The only problem is the hint of distortion and vignetting that you see at 24mm. But both of these can be easily corrected in post-production software such as Adobe Lightroom and Photoshop.

Sigma 24-70mm f/2.8 @ 36mm – 1/500 sec, f/2.8, ISO 160

Image stabilization

The main feature that this lens lacks is image stabilization (IS). That means this isn’t the optimal lens for shooting video. However, this lens works well with Sony’s in-body image stabilization (IBIS), so that gives you some form of stabilization. For non-video shooters, image stabilization in the lens would certainly help for capturing stills handheld at low shutter speeds, but then again, that’s something IBIS can help with.

So at the end of the day, we can’t fault Sigma for not including IS in this lens. The Sony version doesn’t have it either, and the inclusion of IS generally increases the overall price of a lens.

Ease of use in the field

I took the Sigma 24-70mm f/2.8 on a road trip with me. It took the place of my much more compact lens choice, the Sony 24-70mm f/4. My main photo subject was landscape and lifestyle photography, much of it done on cloudy days with even, filtered light. The lens performed beautifully and was a joy to shoot with. The autofocus was snappy and accurate, although the native Sony 24-70mm that I normally use still has the overall autofocus advantage.

The main thing that bugged me about the Sigma lens was its weight and size. Admittedly, I’ve learned to be okay with sacrificing a faster f-stop by using a smaller lens while traveling. This lens felt like it weighed the camera down when I wasn’t holding it in my hands and actively shooting with it. But then again, a larger and heavier lens is the yet another price to pay for using an f/2.8 lens.

Warranty

Besides a lower price, third-party lens companies such as Sigma are one-upping Sony by offering extended warranties. In the case of Sigma, each lens comes with a 1-year warranty, with an extended 3-year warranty in the USA. On the other hand, Sony offers just a 1-year warranty. However, you may be eligible to join the Sony Pro program, which offers discounted repairs.

In conclusion

The Sigma 24-70mm f/2.8 is a solidly built, high performance lens that is a steal at $ 1,099.00. You won’t find a better 24-70mm at this price point. If you’re a stills photographer, you want this in your bag if you don’t already have the Sony version. However, video folks may want to look at another midrange option that includes image stabilization in the lens.

Sigma to Release Canon RF Lenses Next Year

19 May

The post Sigma to Release Canon RF Lenses Next Year appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

sigma canon rf lenses

If you’re a Canon shooter, or you’re thinking about grabbing a Canon body, you’ve probably noticed two big problems with the Canon full-frame (RF) lens lineup.

First, Canon doesn’t offer many RF lenses.

There are around a dozen RF mount options at present, which pales in comparison to the number of lenses offered by mirrorless competitors like Sony, Fujifilm, and Olympus.

And second:

For the RF lenses that Canon does offer, the price tags are huge.

For instance, if you’re a sport, landscape, or event shooter in need of a high-quality 70-200mm zoom, you’re stuck with the Canon RF 70-200mm f/2.8L, which costs over $ 2500 USD.

And if you’re a landscape, travel, or architectural shooter looking for a good ultra-wide lens, the Canon RF 15-35mm f/2.8L is probably the way to go. Unfortunately, it costs just under $ 2300 USD.

So for photographers who want to dedicate themselves to Canon mirrorless bodies but don’t have a huge budget, you’ve got a big problem.

Of course, there’s always the option of using an adapter with Canon EF and EF-S lenses. But this will add bulk and inconvenience to your setup, and it doesn’t take full advantage of the possibilities offered by RF-mount lenses.

Fortunately, it seems that Sigma may be offering another solution.

Because according to Canon Rumors, Sigma may soon come forward with an RF lens announcement.

Sigma has a reputation for producing high-quality glass at excellent prices, which is exactly what Canon full-frame mirrorless shooters are looking for. Even a few Sigma lenses could quickly expand the Canon lens lineup, while also offering some entry-level options for folks who can’t pay thousands of dollars for a single RF mount lens.

While there are not any details on this roadmap as of yet, Sigma is apparently hoping to release lenses starting in 2021. And Canon Rumors’s source suggests that Sigma has sped up its original plans for RF lenses, thanks to the interest generated by the EOS R5 announcement.

The source also revealed that Sigma won’t be modifying their popular ART lenses to fit the Canon RF mount. Instead, Sigma will be developing new glass for Canon shooters.

On the one hand, it’s disappointing to hear that Sigma’s ART lenses won’t make an appearance under the Canon RF label, given how all-around fantastic they’ve turned out to be.

But on the other hand, it’ll be nice to see what Sigma develops.

Now over to you:

What lenses are you hoping that Sigma produces for Canon’s full-frame mirrorless cameras? Share your thoughts in the comments!

Compact, capable and imperfect: First impressions of the Sigma fp

17 May

If you’d asked me prior to the fp’s announcement which company was going to produce the world’s smallest full frame camera, and one with some pretty serious video capabilities, I’m not sure Sigma would have been my first guess. But the specs made it look very tempting indeed.

Key Takeaways:

  • Powerful feature set in compact, adaptable body
  • Good selection of tools for video making
  • 8-bit footage with no Log option (or low-contrast mode) for non-Raw shooters
  • User interface has some oddities: no direct access to ISO setting, under-utilized touchscreen
  • Cine/Stills switch makes it easy to change shooting modes but most settings carry-over, demanding careful re-configuring as you change

We grabbed the fp to see how it would behave for a short (and suitably socially distanced) video project, to see how much Sigma has been able to get right, the first time. These are our first impressions based on that time spent shooting, and as this isn’t a review, we haven’t looked at all the major features just yet. But this is what we found:

What it gets right

The most obvious thing the fp gets right is its basic concept: a tiny video module (that can also take nice stills) stripped back to its core functions so that it can be adapted suit all manner of situations.

To deliver on this underlying idea, a lot of work has clearly been done to provide the features that videographers will want. For a start, there is a waveform display that provides a hugely useful way to assess exposure within a scene, and one that videographers will be familiar with.

The waveform display at the lower right of the screen is a valuable exposure tool.

Then there’s the option to report exposure time as shutter angle, rather than shutter speed. The actual terminology can appear somewhat esoteric when you first encounter it, but even without worrying about what specific ‘angles’ might mean, it means you can easily change the frame rate you’re shooting at without having to adjust the exposure time to match.

Perhaps the defining feature of the camera is its ability to record CinemaDNG files
to an external SSD

The way the zebra exposure warnings are handled will also be familiar to users of higher-end video gear: the fp gives you a choice of using zebras to indicate highlights (ie: indicate the areas exposed at 95% or brighter) or to monitor a specific exposure region (ie shot areas exposed as 70% with an adjustable tolerance level on either side). All of these are key videography tools.

Fins around the edge of the LCD hint at how the fp manages the heat, despite its compact size.

But perhaps the defining feature of the camera is its ability to record CinemaDNG files to an external SSD. There are some drawbacks to this: CinemaDNG can be a bit of a handful and isn’t especially widely supported and, like the Nikon Z6, the footage is sub-sampled to keep the data sizes manageable, increasing the risk of moire. But it lets the fp output files that are more gradable than Log footage without requiring investment in any unusual card formats.

CinemaDNG wasn’t a good fit for this particular project but we intend to look more closely at the results in future.

What’s a bit odd

If you turn on zebras and focus peaking, the zebras don’t appear to work. It turns out you can’t have them both at the same time, so zebras simply don’t appear.

You can easily work around this by defining custom displays modes, one of which has focus peaking turned off. This let me configure a manual focus display mode and an exposure display mode, that I could switch between as I prepared each shot, which is a pleasant-enough way of working. But modes like this aren’t set up by default and nothing on the camera makes it obvious that turning on focus peaking is going to over-ride the zebra settings.

The menus themselves are laid-out in a fairly straight-forward manner

The menus themselves are pretty well laid out, with a Canon-esque horizontal array of pages, broken up into three, color-coded tabbed sections. Vertical tabs tend to be a little faster to navigate but the fp lets you scroll the front dial to jump between pages, so it’s all pretty quick. There’s no option to jump between tabs, though.

The bigger problem (for me, at least) is the camera’s handling of sub-menus. If you go into a sub-menu page there’s not much of a visual indication that you’re no longer in the main menus (and hence need to press ‘Menu’ to retreat back up a level).

Configuring custom display modes is the easiest way to gain access to both focus peaking and zebra exposure warnings

Also, given the camera’s willingness to stream data to an external drive, I was surprised there’s no option to power the camera from an external battery if you need to record for extended periods. You can top the battery up between shots but the camera insists on communicating with anything connected to the USB port while it’s powered on.

Then there are a few of bugs (or, at least, oddities). For instance, if you set a manual white balance, the camera will continue to add on any fine tune values that you’d applied to its previous setting, meaning your new white balance will be off by whatever correction you last used. The camera also seems to turn focus peaking off if left switched off for a while.

The fp also carries most settings (exposure mode, aperture value, shutter speed, WB and color mode) across from stills to video mode, which can entail a lot of re-configuring if you switch between the two. Using the shutter angle option creates a distinct video-only setting, so you don’t accidentally carry fast shutter speeds across to video mode.

What it gets wrong

The single biggest omission I have found on the fp is the inability to adjust ISO using one of the dials. I tend to shoot manually, fix the shutter angle and use a combination of aperture value and ISO to adjust the look of my footage. There’s no easy way to do this, which feels like a fundamental shortcoming.

The dials only control shutter angle and aperture, with no option to reconfigure that, meaning you can’t adjust ISO on the fly. ISO is available in the QS menu, but this means you can’t see your exposure tools (waveforms or zebras) as you’re making adjustments.

The QS menu can be customized but it’s not touch-sensitive, and some sub-options require a complex combination of button presses and dial operation

On the subject of the QS menu, it’s disappointing that both this and the menu menus are not touch sensitive. Tapping on the option you want to change is much quicker than using the four-way controller to navigate. Similarly, just being able to tap between the three main tabbed sections of the menu would be faster than having to scroll though all the individual pages.

The other feature I found myself really missing was the option to shoot Log, to provide a middle-ground between the CinemaDNG output and the standard color modes. There’s no 10-bit gamma-encoded (non-Raw) modes, so your choices are 8-bit H.264 or Raw. There are some interesting color modes provided (Cine and Teal & Orange) in particular but they all have pretty aggressive tone curves: there’s no out-of-the-box equivalent of Fujifilm’s lovely, low-contrast Eterna mode or Panasonic’s Cinelike-D.

Sigma has promised a significant firmware update, so we’re hoping some of these issues can be addressed at that time. Sigma has announced a list of functions that will be added with firmware V2.0 but hasn’t detailed any operational changes, so we hold out hope.

At the end of the project

Shooting early in the morning to avoid encountering people meant the need to just grab shots and keep moving, something which the fp’s modest size and weight really contributed to. Having spent a couple of days familiarizing myself with the camera, I’d become pretty adept at manipulating the QS/AEL/dial combinations needed to change key settings (though apparently not so familiar that I didn’t accidentally knock the camera into the wrong color mode just before starting).

Note the balancing point is roughly in the middle of the lens: the front elements of the 24mm F1.4 weigh nearly as much as the fp body does.

This rather short video, shot outdoors in around 50°F (10°C) conditions didn’t present any temperature challenges for the fp and the roughly ten minutes of footage wasn’t enough to assess battery capacity, but there was nothing to give cause for concern during the time the camera was in use.

It feels like Sigma has tried to address a videographers’ wishlist but doesn’t yet have the experience to make it as slick as it could be

As anticipated, I found that a touch-sensitive QS menu and the ability to adjust ISO on-the-fly would help hugely, as would some more forgiving color/tone modes.

My overriding impression is that it feels like Sigma has tried to address a videographers’ wishlist but perhaps doesn’t yet have the experience in video to make the implementation as elegant as it could be. But Sigma has promised a major firmware update. And it’s also apparent that there’s a lot of capability crammed into the fp, even before exploring one of its defining features by shooting Raw footage.

Aurora Aperture unveils new rear mount filter system for Canon, Nikon, Sigma & Sony ultra wide-angle lenses

16 May

Aurora Aperture Inc. has announced a next-generation rear mount filter system for wide-angle lenses. The new filter system is designed to allow for the use of filters with many popular ultra wide-angle lenses, including those which do not include a front filter thread.

In 2017, Aurora Aperture released a rear mount filter system for the Canon EF 11-24mm F4L USM lens. The newly-announced next-generation system works with the 11-24mm lens, plus the Canon EF 8-15mm F4L Fisheye USM, EF 14mm F2.8L USM (versions I and II), EF 15mm F2.8 Fisheye, EF 16-35mm F2.8L USM (versions II and III are not supported), EF 17-35mm F2.8L USM and EF 17-40mm F4L USM. In addition to Canon lenses, Aurora Aperture’s new filter system is also compatible with the Nikon Nikkor AF-S 14-24mm F2.8G ED, Sigma 14-24mm F2.8 DG HSM Art (Canon EF, Sony E and L mount versions), Sigma’s 14mm F1.8 DG HSM Art for Canon EF mount and the Sony FE 12-24mm F4 G lens.

Not only is Aurora’s latest rear mount filter system compatible with a wider array of lenses, but it also includes other new features. The new rear mount filter system utilizes a magnetic quick-release structure, allowing for easier installation and removal from the lens. In addition, there are a variety of new filters available for the system, including graduated neutral density filters and light pollution reduction filters.

Neutral density – Aurora Aperture refers to them as PowerND – filters are available in 2, 4, 6, 8 and 12 stop variants. Graduated neutral density (GND) filters are available in 1.5, 2.5 and 3.5 stop densities. Each GND filter features a soft transition at 60 percent of the image frame height. Finally, the new PowerDusk filter is designed to filter out artificial lighting and reduce visible light pollution in urban areas, which Aurora Aperture states will allow for better astrophotography and even improved nighttime street photography. For specific information on how the PowerDusk filter reduces the light which hits your image sensor at different wavelengths, click here.

In order to utilize the magnetic filters on the rear of your wide-angle lens, you must first install the new rear mount filter system. The installation process will vary depending on the lens in question, but it ranges from using specialty adhesive to replacing existing gel filter holders. Once the filter holder adapter has been installed, using and changing filters is as placing a small glass filter into the magnetic filter holder.

The Aurora Aperture next generation rear mount filters will be available through a Kickstarter campaign starting this month and general availability is expected in September. The price of lens adapters range from $ 35 to $ 41 USD and filter prices range from $ 43 to $ 113. Stay tuned to Kickstarter and to Aurora Aperture’s website for additional information and availability.

Sigma interview: Smaller, high-quality lenses coming ‘in the near future’

30 Mar
Kazuto Yamaki, CEO of Sigma, pictured in his company’s plant in Aizu, Japan when we visited in 2015.

The photo industry is recovering from the disruption in global supply chains caused by Chinese shutdown, but with the rest of the world still in crisis, companies are preparing for a major drop in customer demand, especially in the US and Europe. Last week I spoke to Kazuto Yamaki of Sigma to get his take on the ongoing situation worldwide, and on Sigma’s strategy for the next generation of cameras and lenses.

Please note that this interview was conducted remotely, and has been edited for clarity and flow.


Mr. Yamaki, I last spoke to you two weeks ago, which feels like a year ago. What has changed in those two weeks?

Two weeks ago I was mainly concerned about the production system, and the supply chain. We make all of our products in Japan and make most of the parts by ourselves or by Japanese local suppliers, but some parts such as electronics are supplied from China, therefore, I was concerned about the supply of parts. But in fact, up to now we haven’t had a serious problem with that. Some parts have been delayed due to confusion in the supply chain but it hasn’t been serious, and we’ve been able to adjust our production planning.

Production and delivery systems in China are starting to normalize

So on the production side, we haven’t had a serious problem. And we don’t expect to have problems in the future, because production and delivery systems in China are starting to normalize.

I was also really concerned about sales in China. At the beginning of March, my worst-case scenario was a halving of sales compared to last year. But in fact our business in China is quite stable, and not too bad, which is a big relief. Sales in China are still doing OK because there’s a very strong online business. Right now the biggest concern is the market situation in Europe and the USA. I had never imagined such a crisis in Europe and America.

How are things in Japan?

It’s not a crisis situation, like in some parts of the US or in Europe. People are walking in the streets, and coming back to stores. It’s not as bad as it is in other countries. But for the photo industry it’s really bad. Since the beginning of March, we’re seeing a decline in sales in the Japanese market, but we will have to wait for a while to get a picture of the full situation.

Sigma’s Aizu factory in northern Japan is still where all of the company’s lenses and cameras are assembled, with a primarily domestic (i.e., Japanese) supply chain. This makes Sigma unusual among modern manufacturers in the consumer digital imaging space.

So to some extent, life is returning to normal in parts of China?

This is what I’ve heard. People are starting to return to the streets, and our staff in China are reporting a positive mood in the towns.

What effect do you think that this crisis will have in the long term?

To be honest I don’t know. Some countries have already decided to lock down cities for weeks, even months, and this will affect our business. I don’t want to be too negative, but the situation may not improve in the short term.

Do you have any idea of what portion of your sales in Europe and the US are online?

It’s a bit too early to say that, but in Europe, it doesn’t look like online business can compensate for the loss of sales from physical stores. Some online retailers are also prioritizing food and sanitary goods because of the high demand, so shipments of cameras and lenses are being de-prioritized.

Sigma’s ‘DC’ trio of native mirrorless lenses (now available for Canon EF-M, Sony E-mount and Micro Four Thirds) has proven a hit, with demand regularly outstripping supply in some markets.

Has this crisis revealed any vulnerabilities in the current structure of the photography industry – for example within the supply chain?

Well, this is not the first time. We had similar problems when the earthquake hit Japan in 2011, and also a flood in Thailand. The global supply chain was thrown into total confusion. I think we’re aware of such risks. Sigma has a relatively short supply chain. As you know, most of our suppliers are located in Japan, and we work with them directly. However, some of those suppliers do outsource certain components to other suppliers, called ‘second-tier’ suppliers.

Most companies have a very complicated structure, with first-tier suppliers, second-tier suppliers, and sometimes even third-tier. But in the case of Sigma, our supply chain is quite simple, so it’s easy to control the situation.

Let’s move on from talking about coronavirus – you recently said that going forward, Sigma would prioritize development of native mirrorless lenses over lenses for DSLR. Can you explain that decision?

It’s simply because we’ve had higher demand for mirrorless lenses. The mirrorless camera market is stable compared to DSLR. If you look at the market statistics you’ll see that the decline in DSLR sales is quite significant. This decline gets steeper every month.

We’re also seeing a decline in sales of our DSLR lenses, so naturally we have to focus our efforts on the development of mirrorless lenses.

Demand for Sigma’s ‘DN’ (Digital Native) range of lenses for mirrorless mounts has outstripped demand for lenses made for traditional DSLR lens mounts. For this reason, Sigma is prioritizing development of native mirrorless lenses.

How have the full-frame ‘DN’ lenses performed in the market since they’ve been released?

They’re doing very well, especially our 24-70mm F2.8. It’s been very well-received. We’re still catching up to demand for that lens. We’ve been enhancing our manufacturing capacity, continuously, but we still can’t meet demand. Even in the current difficult situation, demand for that lens is still very strong.

What portion of your DN sales are L-mount lenses?

It’s tough to say. Most of the lenses we’re shipping of course are for Sony E-mount. It’s too early, and we don’t have a big enough lineup to make our potential customers feel comfortable with the L-mount system. Changing systems is a big decision for the customer. There are a lot of potential customers out there, but I think they’re waiting and seeing how the L-mount system develops. I think we need one or two more years before we have a complete L-mount system. Not only from Sigma but also Panasonic and Leica.

Last year you released your first full-frame camera, the fp. How has it performed in the market?

It sold quite well at the beginning. Early adopters were very interested, and purchased the camera immediately. We’ve received a lot of emails from customers, which I’ve read, and we have a lot of customers who are very happy and satisfied with the fp. We’ve also been monitoring feedback online, through Facebook and Twitter; things like that.

To be honest though, sales have declined considerably [since launch], especially in Europe and America. It’s still selling well in Japan, but overall sales have been lower than expected.

The fp is an ultra-compact full-frame camera aimed at photographers and filmmakers. In order to minimize its size, Sigma designed the fp with a fully electronic shutter. Mr. Yamaki believes that this will act as a model for the ‘camera of the future’.

Why do you think that is?

There are several reasons, I think. First of all, changing systems is a big investment for customers. So even though we have potential customers who are really interested in the camera, I think a lot of them are waiting to see how the L-mount system develops. We don’t have enough compact lenses, suited to the fp. We’re currently developing several lenses of that type. Once we have that kind of lineup, I think a lot of potential customers may decide to buy the camera.

Due to the coronavirus crisis, we had to cancel many events. So we’ve lost an opportunity to let customers try our camera

That’s one thing. The second thing is that in Japan, we’ve found that ‘touch and try’ events have worked really well in convincing customers that the fp is a good camera. After they try it, many of them buy it. We had a plan to conduct many such events, but due to the coronavirus crisis, we had to cancel many events in Japan, in China and in Europe. So we’ve lost an opportunity to let customers try our camera. That’s disappointing, but once things calm down we’ll start again.

So when a show like CP+ or NAB is canceled, what impact does that have on a manufacturer like Sigma?

It’s difficult to evaluate the value of such events, today. But if you take CP+, it’s basically a consumer show. Typically we see people there who are excited by new products, and we can use that excitement to create some momentum. So it’s definitely not a good thing to lose such opportunities.

A typical scene from CP+ 2019, showing the density of the crowd as enthusiasts flock to get their hands on the latest photo gear. This ‘hands-on’ experience is precious when it comes to converting customer interest into sales, and manufacturers are feeling the effect of so many canceled shows in 2020.

Can you talk more about the development of smaller lenses?

Going forward, we will still try to deliver the highest-possible quality products. But we will have two main streams of products. One is for very serious photographers, like our existing ‘Art’ series. But another line will be high quality, premium lenses, but much more compact. And very stylish, like our 45mm F2.8, with metal housings, and high quality aperture and focus rings. We will expand that kind of range for street photographers, or those who need smaller, stylish, high-quality products.

So our readers can look forward to a range of smaller lenses from Sigma, with Art-series optical quality but more modest maximum apertures?

Yes, that’s our goal. You’ll probably see such products in the near future.

Sigma is committed to making more compact lenses, like the 45mm F2.8 ‘Contemporary’ for L and E-mount in future.

Do you think that the fp range will evolve to include things like a mechanical shutter, and viewfinder?

If we made the fp with a mechanical shutter, it would not be so compact. One of the reasons it’s so small is that we eliminated the mechanical shutter. We created the fp as a kind of platform for a ‘future camera’. I think in future, most cameras won’t have a mechanical shutter, because of improvements to the readout speed of sensors. I haven’t made any decisions about future products, but we’ll probably keep that concept.

You recently announced the postponement of your planned Foveon sensor full-frame camera. Can you give us more details about why that project was postponed?

The development of the sensor has been significantly delayed. We are still working on it, but there are still several technical problems we need to overcome. If everything goes well, we should be able to release the camera next year. But if we continue to face technical problems the camera may be delayed further. We haven’t stopped developing the camera, but without the sensor we can’t move very fast.

Are you interested in creating a full-frame alternative to the DP Merrill fixed-lens camera concept?

We don’t have any plans to do that right now. We are researching the market, but it’s difficult to make such a camera really compact. Of course there are cameras like the Sony RX1R II, which is a very small camera, but it’s difficult to make the lens compact. If we wanted to make a really compact lens, our options for focal length and F stop become very limited. Compared to APS-C or M43 cameras with a fixed lens, it’s very challenging, technically.

Our mission is to support as many mounts as possible, but due to limited engineering resources, we have to be selective

Is there anything you can say to our readers about the possible development of Canon RF, Fujifilm XF and and Nikon Z-mount lenses from Sigma?

As a lens manufacturer, we believe that it is our mission to support as many mounts as possible, but due to limited engineering resources, we have to be selective. We are watching the market.

How have your ‘Classic’ cine lenses been received?

Very positively, especially for filmmakers looking for a unique rendering. These lenses create huge ghosting and flare, so they’re not easy to use. Especially if there is a direct light source in the frame. But if you carefully control the lighting, it can create a very nice, soft, ‘retro’ kind of look. High-end filmmakers in Hollywood have received these lenses very positively.

Do you know of any productions that are using these lenses?

It’s still very early, we only started shipping in January and February, so we don’t have that kind of information yet. But we made a film, ourselves, it’s about 30-40 minutes long. We shot the entire thing on the Sigma fp, and we used our regular cine lenses, and in some scenes the ‘Classic’ lenses were used. We need to apply to some film festivals, and after that will release the movie online. Probably in the near future.

Do you think that your DC DN lens lineup will grow? It’s been three lenses now for quite a long time.

Actually, demand for those lenses keeps growing. It’s really surprising. In terms of units, they’re the top seller for Sigma right now. It’s a surprise because in general the market for APS-C cameras and lenses is declining. But sales of those three DC DN lenses keep growing. Most of the sales are for Sony E-mount and Micro Four Thirds [versions], and in peak seasons sometimes we actually can’t keep up with demand.

Do you still see a healthy market for Micro Four Thirds?

Yes, I think Micro Four Thirds is well accepted by filmmakers, and our 16mm is really popular among M43 users. People who need a compact system still love Micro Four Thirds.


Editors’ note: Barnaby Britton

In the two weeks since I spoke to Mr. Yamaki last (for this article) a lot has changed. Only a few days ago, his biggest concern was getting hold of parts from China, and a significant slowdown in Chinese consumer spending. Now, with countries all over the world in virtual lockdown, and US and European governments bracing for a catastrophe in their healthcare systems in the coming days, such worries seem almost quaint.

It remains to seem how quickly – and to what extent – markets will recover, but there are some tentative signs of hope. Mr. Yamaki tells us that the situation in China is stabilizing, and the mood in the country is positive. Japan seems (for now, at least) to have escaped the worst social effects of the COVID19 outbreak, and South Korea has employed pioneering test and trace technologies to address what could have been a catastrophe.

Away from the immediate crisis, Mr. Yamaki tells us that demand remains strong for some of the company’s products, particularly the ‘DN’ range

The same sadly cannot be said of Europe or the US, and with consumers in those territories tightening their belts in the face of economic turmoil, it’s not hard to understand why Mr. Yamaki still characterizes the situation for the photo industry at this early point in the year as ‘really bad’.

There are tough times ahead, without a doubt, for all of us. But away from the immediate crisis, Mr. Yamaki tells us that demand remains strong for some of the company’s products, particularly the ‘DN’ range of native mirrorless lenses. These include the 24-70mm F2.8 DG DN Art, and the trio of ‘DC’ lenses for APS-C. This latter range, in fact, appears to be a genuine success story.

It seems that we’ll have to wait a little longer for Canon RF and Nikon Z support

Support for Canon EF-M has been added to the ‘DC’ range but in the full-frame arena, it seems that we’ll have to wait a little longer for Canon RF and Nikon Z support. As Mr. Yamaki says, he wants to support as many mounts as possible, but his engineers can’t do everything; they have to be selective.

It’s also likely that the communication protocols that make these new mounts work are protected I.P., and need to be licensed. It’s entirely possible therefore that just like their customers, Sigma’s engineers are waiting patiently too: in their case for the original manufacturers to open the protocols up to third parties, before any decisions can be made.

Coming soon though, we’re told, is a range of small, lightweight lenses specifically designed to be a better match for cameras like the fp. A range of more compact, slower maximum aperture lenses but with ‘Art’ series image quality is a longstanding request from Sigma fans, and it’s great to have confirmation from Mr. Yamaki that these are on their way ‘in the near future’ for L and – safe to assume – Sony E mount, too.

Coming soon… is a range of small, lightweight lenses specifically designed to be a better match for cameras like the fp

Meanwhile, Sigma continues to make inroads in the filmmaking community. Sales of the hybrid stills / video fp may be slowing, but Sigma’s range of Cine lenses have proven popular with filmmakers, and Mr. Yamaki tells us that the response from Hollywood to its range of ‘Classic’ cine lenses, designed with minimal coatings to give a retro look to footage, have been received well.
