Venus Optics’ new $549 7.5mm F2 MFT lens now has electronic aperture control

11 Jun

Venus Optics has announced an updated version of its Laowa 7.5mm F2 Micro Four Thirds (MFT) lens that has electronic aperture control and an onboard chip for transferring metadata from the lens to the camera.

The new lens features the same optical construction as its fully-manual predecessor (13 elements in nine groups), but adds an electronically-controlled aperture at the cost of reducing the number of aperture blades to five (there are seven in the manual version).

As for dimensions, the lens comes in at 3mm (.12”) larger in diameter and 7mm shorter (.28”) than the manual version. Also, despite adding the electronic aperture control and onboard CPU chip, Venus Optics managed to reduce the lens’ weight to 150g (5.3oz), down from the 170g (6oz) weight of the manual version.

Below is a video review of the lens from YouTube channel RED35:

Are mechanical film cameras better than electronic?

There are a lot of mechanical film camera snobs out there, and I’m one of them. There’s something about the way a mechanical camera feels, that sensation of meshing gears and tightening springs that you can feel right in your fingers, which is just magical. To me, a camera that goes ‘KA-CLACK!’ will always be superior to one that goes ‘bzzzt.’

But I also know that electronic film cameras have key advantages over mechanical cameras, and those advantages don’t always get proper recognition. In fact, I’d argue that for many photographers and many situations, electronics are better. Here’s why.

Mechanical vs. Electronic: What do we mean?

Before we begin, some quick definitions: For the sake of our discussion, an all-mechanical camera is one that has no electronics in the shutter, exposure or film-winding mechanisms. It may have a light meter, but mechanically speaking, it’s fully functional without a battery.

An all-mechanical camera is fully functional without a battery

When we talk about electronic cameras, we either mean cameras with an electronically-controlled shutter, which still have manual focusing and winding, or cameras with electric/electronic everything, including shutter, exposure control, winder, and (usually) autofocus. Some electronic cameras will work at one shutter speed (usually the flash sync speed) with no batteries; for others, no power means no pictures. (Note that some cameras, like the Canon EF and Pentax LX, use a hybrid shutter with mechanical timing for fast speeds and electronic for slow speeds.)

Some electronic cameras will work at one shutter speed (flash sync) with no batteries; for others, no power means no pictures

Got it? Good! Let’s dive in and talk about the advantages of electronics, then we’ll revisit a few of the arguments in favor of mechanicals.

Why electronic cameras are better

You’d be hard-pressed to spend more than $ 75 on an electronic Ricoh KR-10 with lens.

Electronic cameras have fewer moving parts than mechanical cameras.

This is one of the main reasons camera manufacturers moved to electronics in the first place: The complexity of the mechanism is greatly reduced. Mechanical cameras are clockwork marvels, filled with minuscule gears, levers, springs, cords and chains – moving parts that can wear out, disengage, clog up or break. Electronic cameras replace a lot of these intricate bits with non-moving solid-state electronics, which are simpler, more robust and generally more reliable. From the manufacturer’s perspective, electronics make the cameras cheaper to build. From the photographer’s perspective, electronics mean fewer things to go wrong.

From the manufacturer’s perspective, electronics make the cameras cheaper to build. From the photographer’s perspective, electronics mean fewer things to go wrong

Electronic cameras rarely go out of adjustment.

One of the problems with a mechanical shutter-timing mechanism is that it’s subject to wear, degraded lubrication, and temperature variations. After a while, your 1/250 shutter setting no longer delivers a 1/250 second exposure. (Hence the ‘A’ in the common CLA service – cleaning, lubrication and adjustment.) With an electronic shutter, the timing is done by solid-state bits that are not prone to such discrepancies.

That’s not to say electronic shutters are always perfect; they still have moving parts that can be affected by dirty electromagnets or dried-up lubricant. But they tend to stay pretty darn close to the mark. If a forty-year-old electronic camera is working, it’s probably working correctly – and will likely be shooting more accurate than an older mechanical camera that hasn’t been serviced.

Electronic cameras can deliver more precise exposures than mechanical cameras.

With a mechanical camera, you’re generally locked into pre-set full-stop shutter speeds – 1/500, 1/250, 1/125, 1/60, etc. Same with an electronic camera in manual mode. But electronic cameras with an automatic exposure setting can take advantage of one of the key benefits of an electronic shutter: Infinitely variable speed settings. If the meter decides the ideal shutter speed is, say, 1/300 of a second, that’s how long the shutter will stay open. 1/75 sec ? No problem. 1/854 sec? Sure! They can fine-tune your exposure in a way that a mechanical camera can’t, which is especially critical if you’re shooting with slide or technical film.

Electronic cameras have faster top and sync speeds than mechanical cameras.

The camera with the fastest purely mechanical shutter I know of is the Nikon FM3A, which tops out at 1/4000th of a second, but that’s atypical; most mechanical cameras stop at 1/1000 sec, and some ‘pro’ models at 1/2000 sec. So did early electronic cameras, but advances in electronics and curtain materials meant faster speeds, and many electronic cameras top out at 1/4000 or (in very high-end models) 1/8000 sec. The speed champ is the Minolta Maxxum 9, which can snap off an exposure in 1/12,000 sec.

Fast shutters are usually associated with action photography, but they are handy for casual shooters as well: If you’re running 400 speed film and the sun comes out, you can still shoot at wide apertures. Electronic shutters also give you faster flash sync speeds, typically 1/125 sec to 1/250 sec versus 1/60 sec for most mechanical shutters. Again, that’s one or two more stops of flexibility, allowing you to use a wider aperture for outdoor portraits with fill flash.

Electronic shutters also give you faster flash sync speeds, typically 1/125 sec to 1/250 sec versus 1/60 sec for most mechanical shutters

Finally, my favorite:

Electronic cameras are usually less expensive.

Electronic cameras are the bargains of the used-film-camera market. Nikon’s all-mechanical FM2 typically sells for twice as much as its electronic-shutter counterpart, the FE2. Same for the mechanical Pentax MX and the electronic ME Super.

And the more electronic you go, the better the prices get. The Nikon N8008, a “prosumer” camera one notch below the vaunted F4, sold for $ 600-$ 800 when new, but today you can buy them for $ 10-$ 50. Minolta’s excellent Maxxum/Dynax autofocus cameras of the 1990s can easily be bought for $ 20-$ 50 in good operating order with a Minolta lens – not just the low-end consumer models, but fully-featured high-end cameras as well.

Why mechanical cameras are better

We’ve covered the advantages of electronic cameras. What about the arguments in favor of mechanical cameras? Let’s discuss a few.

A Nikon ad from the 80’s showing a mix of electronic, mechanical and hybrid cameras.

Mechanical cameras work without batteries.

This is true, though I’ve personally never seen it as a real advantage (although I can understand how those who have found themselves on the losing end of a dying digital camera battery would). The story I’ve heard is of a professional photographer on a once-in-a-lifetime shoot atop an icy mountain. Suddenly their camera’s battery dies – but they have a mechanical camera, so they can go right on shooting! Fine – but that’s a niche use-case. Most of us aren’t going to be shooting regularly in situations where batteries degrade fast (like extreme cold) or in places where spares aren’t easily available.

The more likely explanation for the cult of the battery-less camera is that pros mistrusted electronics when they first came out, which is a natural human reaction to anything new and unfamiliar. Within a few years, once they realized that electronics were not evil, those same professionals were relying on battery-reliant cameras like the Nikon F4/F5 and Canon EOS-1.

All-mechanical cameras are fabulous beasties and a treat to use. But manual-wind, manual-focus cameras with electronic shutters give you most of that same feel.

Besides, while it’s true a mechanical camera will work without the batteries, its meter won’t, and who wants to shoot without a meter? Sure, you can use an external meter/phone app or ‘Sunny 16’, but there’s no need for a fallback when spare batteries are cheap and easy to carry. Remember that electronic cameras that use button batteries go years on one set, and autofocus cameras that use AAs or lithium ions should give you a few dozen rolls and a warning before the batteries die. So yes, this argument is valid, but I don’t think it’s very relevant.

Mechanical cameras are more repairable.

There is some truth to this. One of the reasons older electronic cameras can fail is that their flexible printed circuit boards can crack with age. When new parts aren’t available, repair shops rely on donor cameras, which may have the same age-related issues. But not all problems with electronic cameras are insoluble – some repairs require a bit of soldering, and other failures are mechanical, not electrical, and involve the same types of issues to which mechanical cameras are prone.

Even if a given camera cannot be repaired, remember those low replacement costs. I’ve had two cameras cleaned and repaired at a cost of around $ 100 each– worth it for more expensive cameras. But if it’s my Minolta 400si or Ricoh KR-10 that breaks, for that same $ 100 I could buy 3 or 4 replacement bodies in working condition.

Mechanical cameras have more ‘soul’.

You’ll get no argument from me there. All-mechanical cameras are fabulous beasties and a treat to use. But manual-wind, manual-focus cameras with electronic shutters give you most of that same feel. And while autofocus, auto-wind cameras don’t feel the same, using them is a unique experience that I have grown to appreciate.

Bottom line

Mechanical cameras are great, and they have their advantages, and disadvantages. Electronic cameras, meanwhile, are the unsung heroes: They are generally cheaper to buy, more likely to give you accurate exposures, and if they aren’t always easily repairable, they are usually easily (and cheaply) replaceable. There’s a reason all camera manufacturers embraced electronics. We, as film photographers, ought to embrace them as well.

Canon EOS R5 on the Way, With a 45 MP Body and 20 FPS Electronic Shooting

05 Feb

The post Canon EOS R5 on the Way, With a 45 MP Body and 20 FPS Electronic Shooting appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

canon-eos-r5-news

After months of vague rumors regarding upcoming Canon mirrorless bodies, we now have specifics on a camera, right down to the name:

The Canon EOS R5.

While still unconfirmed by Canon, the EOS R5 is shaping up to be a powerhouse of a mirrorless camera, sporting a 45-megapixel full-frame sensor, in-body image stabilization (potentially 5 stops, and 7-8 stops with a combined IS lens), and 20 frames-per-second continuous shooting with the electronic shutter (12 frames-per-second with the mechanical shutter).

In fact, the EOS R5 appears to correct most (if not all) of the faults of Canon’s first full-frame mirrorless body, the EOS R:

First, instead of a single card slot, we’re on track to see dual slots in the R5. This is a necessity for pretty much any photographer who requires redundancy in their work, such as professional wedding shooters (after all, you can’t reshoot that big day if your card fails!), as well as professional sports photographers.

The programmable touch bar on the back of the EOS R, which received significant criticism following the R’s release, will be replaced by a scroll wheel.

And, as mentioned above, we should see some impressive IBIS, something which the EOS R left out, and which plenty of shooters see as a key trait in mirrorless bodies.

Astonishingly, the EOS R5 is reported to shoot 8K video at 30 fps and 4K video at 120 fps. While the details of these specs aren’t certain, 8K video of any kind would be a significant upgrade from the Canon EOS R, which offers 4K video at 30p.

So who is the EOS R5 for?

From the specs listed above, it’s clear that the EOS R5 will be aimed at professional shooters. The dual card slots and high continuous shooting rate suggest a body designed for serious sports photographers, wildlife photographers, and some wedding photographers. And while no details on the autofocus system have been released, I suspect that we’ll see something impressive, even compared to the excellent AF offered by the EOS R.

As far as the release date goes, the Canon EOS R5 will supposedly be announced in mid-February, several weeks prior to the late February CP+ show. The camera will likely ship in July.

Kipon releases two Mamiya 645 to Sony E mount adapters with electronic aperture control

29 Oct

Photography accessory manufacturer Kipon is now shipping two new adapters for mounting medium format lenses to Sony E mount camera systems.

The adapters come in two varieties: the M645-S/E E, which adapts Mamiya brand Mamiya 645 mount lenses to Sony E mount cameras while the M645-S/E ES adapters Phase One or Schneider brand Mamiya 645 lenses to Sony E mount cameras.

The two adapters are constructed of aluminum and brass, offer an infinity focus feature, and offer electronic aperture control through the camera. A previous Mamiya 645 to Sony E mount adapter has been available for some time, but it doesn’t offer the electronic contacts for aperture control and features a less pleasing design.

The M645-S/E E and M645-S/E ES are available to purchase for $ 289 and $ 389, respectively. Shipping dates vary depending on your geographical location.

Optical Versus Electronic Viewfinders: Which is Best for You?

14 May

In this article, we’ll take a look at optical versus electronic viewfinders so you can get a better understanding of the differences and strengths and weaknesses of each.

Coke versus Pepsi, Star Wars versus Star Trek, football versus futbol. The world is full of great rivalries, and photography is no exception. Aside from simple brand loyalty and lens preference, there are dozens, perhaps hundreds, of other tools, features, and options that photographers to argue about. One of the most recent but most pronounced has to do with how you see the world in front of your lens.

Some cameras have optical viewfinders while others sport more technologically advanced versions called electronic viewfinders. Other cameras even have hybrid options that attempt to combine the best of both worlds. So which is better? Just like most rivalries, that question is impossible to answer, but it is worth exploring some of their individual strengths and weaknesses to help you know which one might be right for you.

Optical Versus Electronic Viewfinders - low angle sunset shot

Seeing the scene

A viewfinder is one of the most basic elements of any camera; it’s what you use to look at what you will be photographing. When you hold your camera up to your eye, whether you’re shooting DSLR or mirrorless, the tiny little hole you look through is what’s known as the viewfinder. This is what you use to compose your shots.

Some cameras forego the viewfinder altogether and just have a giant LCD screen on the back, which is how all mobile phones work. But it’s not uncommon for many cameras to include a viewfinder along with the rear screen.

It’s not just a holdover from days gone by, and even in today’s fast-paced tech-centric world, there is a myriad of reasons why many photographers prefer to compose their shots with the viewfinder instead of the rear LCD screen.

  • The scene appears much larger when held up to your eye which gives you a better sense of how your picture will look.
  • Holding your camera up to your face also has the rather practical benefit of making things more stabilized.
  • Viewfinders in DSLR (and more mirrorless) cameras often contain a row of numbers and indicators at the bottom showing you things like your aperture, shutter speed, metering mode, shots remaining, and more.
Optical Versus Electronic Viewfinders - inside the camera view

Optical viewfinders have a row of exposure and photo information at the bottom to help you as you shoot pictures.

Optical Viewfinders

Despite being decades-old technology, optical viewfinders still have many staunch supporters in photography today, with good reason. Their most important benefit, and the reason many photographers prefer them, is that they present an unfiltered and unaltered view of the scene in front of you as you are composing your shot.

Looking through an optical viewfinder, or OVF, is no different than looking through a window: nothing is changed in any way, shape, or form. This lets you see exactly what your shot will look like, and the view is not dependent on any type of fancy technology in order to function.

Optical viewfinders work even if your camera is turned off, in much the same way that looking through binoculars, a telescope, or even a paper towel roll does not require a battery. OVFs have no issue with accurate color rendition or screen refresh rates, and they work the same in bright light as they do in low light.

Optical Versus Electronic Viewfinders - crowd watching a speech outdoors

Most optical viewfinders also have indicators to show things like focus points and framing guides. When you half-press the shutter button to focus your camera, a small dot or square will show up in your camera’s OVF to let you know where the point of focus will be, and you can use a dial or knob on your camera to change this if you prefer.

Limitations of OVFs

However, not everything is sunshine and roses in the land of optical viewfinders. They do have some significant limitations that could be a factor depending on the type of photographs you take.

One of the most important is that you can’t see your image when you take a picture – a phenomenon known as viewfinder blackout. When you press the shutter button the mirror in a DSLR camera flips up and out of the way to let light pass through to the image sensor, which means the OVF goes completely dark.

This is not very noticeable when using fast shutter speeds but if you are shooting at about 1/30th of second or slower you will see a big blank box of nothing for a brief moment whenever you take a picture. In most situations, this blackout period is not going to make or break the photograph but it can cause issues if you are shooting fast-moving subjects. In those cases, the short amount of time that the OVF is blank is enough for the object you are photographing to move around quite a bit and it can take some practice to get used to this type of shooting.

Disadvantage

Another disadvantage of optical viewfinders is that they show you the world around you as it really is, not as it will appear in your digital photograph. The OVF sees what your eyes see, which is not necessarily the same as what your camera’s image sensor sees.

Unless you have a solid grasp on metering modes and how they affect your exposure, you might end up with pictures that are too bright or too dark, especially if there is a great deal of light and shadow in the scene itself. Looking through the OVF you might think your pictures are going to be just fine only to realize later that they are under or overexposed. Unless you shoot in RAW there might not be much you can do about it.

Electronic Viewfinders

A few years ago, this discussion about optical versus electronic viewfinders would have been more of an academic exercise without a whole lot of practical value because EVFs simply couldn’t compete with their analog counterparts in practical terms. Their list of downsides was as long as a 70-200mm lens, and aside from a few key benefits, there wasn’t much reason to use an EVF compared to an OVF.

However as time marches on and technology gets better and better, electronic viewfinders have now just about reached parity with optical viewfinders. They are not just a viable option, but in some cases are a superior one for some photographers.

Main difference

The most obvious difference with electronic viewfinders is that just like looking at the LCD screen on the back of your camera, you see a digital representation of the world in front of your camera instead of the actual world that your eye sees. An EVF is a tiny high-resolution screen that you hold less than an inch from your eye. Because it is entirely digital, it can show you a wealth of information and data that you simply can’t get with an optical viewfinder.

Benefits and bonuses of EVFs

While optical viewfinders have static overlays with framing guides and focus points splayed across your field of view, electronic viewfinders can show all kinds of information that is highly useful when taking photographs. You can see things like a live histogram and digital level along with the usual collection of exposure and metering information. But the ace up the sleeve of any OVF is its ability to show you exactly what your photograph will look like, not what the world in front of the lens looks like.

Electronic viewfinders will let you see instantly, in real-time, whether your shot is exposed correctly. This allows you to quickly made adjustments not based on a light meter (though you certainly can) but on the final image and how you want it to appear.

Things OVF can’t provide

If you’re shooting in a black and white mode, then that’s precisely what you will see as you look through the EVF to compose your image. You will also see the depth of field reflected exactly as the final image will appear, and you can watch it change in real-time as you adjust your focus point or aperture.

To put it simply, EVFs remove much of the guesswork inherent in OVFs. In many cases, this makes the act of taking pictures much easier, especially for new photographers.

pink flowers - Optical Versus Electronic Viewfinders

Getting the exposure right on this shot was easier thanks to the electronic viewfinder in my Fuji X100F.

Due to their electronic nature, EVFs gives you options that an OVF is simply incapable of doing. Many cameras with EVFs allow you to check focus by enlarging a portion of your image so it fills the screen, and you can often get visual aids like focus peaking in the EVF as well. You can use an EVF to go through menus, review pictures, and even record and review movie footage you have captured with your camera–all things that are impossible with an OVF.

Drawbacks of EVFs

There are, as you might expect, some important downsides to EVFs not the least of which is power consumption. Optical viewfinders work without any batteries at all, whereas electronic viewfinders require constant power to operate. It’s not uncommon for cameras that rely on electronic viewfinders to have much shorter battery lives than their optical counterparts, and many photographers who use these cameras are in the habit of carrying spare batteries for a day of shooting.

Electronic viewfinders also suffer from screen refresh rate issues, which means that they can be difficult to use in situations with a lot of fast-moving action. Some EVFs have a great deal of lag which means the image you see is just slightly behind what is actually happening. While they have certainly gotten much better in recent years, they are still not quite on par with optical viewfinders in this regard (in my opinion).

Finally, even though electronic viewfinders show you a good representation of what your final image will look like they don’t quite have the same color range and resolution as what you will see in your photographs. Even the best EVFs top out at 3 megapixels with most hovering around 1-2, which means you’re looking at a much lower-resolution version of what you will see in your pictures.

So which is better?

Like many aspects of photography, this issue isn’t about whether an optical versus electronic viewfinder is better, but which one will suit you and your needs as a photographer. Some people prefer the analog precision of an optical viewfinder, while others like the high-tech features offered by electronic viewfinders. At the end of the day, what really matters is that you have the right tool for the job. So if you tend to prefer one of these over the other then, by all means, go ahead and use it.

I would like to add one caveat to all this, which is if you have not used an EVF in a few years you might want to give it a try. The shortcomings of EVFs are rapidly being addressed by many camera manufacturers today, and EVFs from days gone by have been eclipsed many times over by their modern counterparts. It might be worth your time to go to your local camera store and check out one of the newer models with a built-in EVF and see what you think, just so you can make an informed decision when choosing your next camera.

Canon patents innovative lens adapter with built-in electronic ND filter

27 Jan

A Canon patent from October, 2017 resurfaced on the Canon rumor mill today, and it describes something pretty innovative from the Japanese camera giant. The patent shows a lens adapter—ostensibly designed for a mirrorless camera—that features a built-in variable-voltage ND filter.

The ND filter component is “formed from an electrochromic device [or a liquid crystal element] which changes light transmittance on application of a voltage.” That way, you could electronically and silently change the amount of light hitting your camera’s sensor without stopping down the lens.

As Canon News points out, this would be particularly useful for video shooting, since it’s silent, and it would allow you to separate depth-of-field control from brightness (i.e. shoot with a shallow depth-of-field in bright light).

We could see this technology more readily appearing in a Cinema EOS system, but Canon has (naturally) written the patent as broadly as possible so that no one else can use the idea for stills. Canon Rumors also speculates that it might be the patent behind a rumored EF/EF-S to EF-M adapter specifically designed to adapt cinema lenses to an EF-M mount camera.

As always with patents, it’s impossible to know what parts of this idea—if any—Canon plans to bring to market. But it’s a rather innovative design that we wouldn’t mind seeing in action.

Novoflex introduces electronic lens reversing system for Sony E-Mount

02 Nov

German accessories manufacturer Novoflex has launched a version of its Retro Reverse Adapters for the Sony E-mount system. The adapter allows users to reverse-mount lenses for macro shooting while maintaining full electronic control of the lens via the body controls.

The system works by using a pair of cable-connected rings that communicate information from the camera to the rear of the lens, even when it is mounted away from the body.

Reversing a lens is a quick way of achieving macro and close-up abilities, but Sony E-mount lenses need to be connected to the camera to operate at apertures other than the widest. This adapter, which has been available for Canon EOS users for some years, allows the lens to be mounted in reverse with no loss of control or EXIF information.

The adapter also allows a bellows unit to be fitted between the camera and any Sony E lens, reversed or not, for extra-high magnification work while still maintaining contact between lens and body.

The Novoflex NEX-RETRO will retail for $ 440/£309/€350. For more information, visit the Novoflex website.

Press Release

Sony Users Now GO RETRO with NOVOFLEX!

New NEX-RETRO from NOVOFLEX

Allows users with Sony E-Mount cameras (e.g. Sony Alpha 7/Alpha 9 series, Alpha 6000 series, etc.) to reverse mount their existing lenses to achieve closer focus. NEX-RETRO transfers all electronic functions such as aperture control, EXIF data and autofocus, from the reversed lens to the camera body as if it were mounted directly.

Look More Closely

With a 18-105 mm zoom lens in reverse position, you get an image ratio of 1:7 at 105 mm and 2.8:1 at 28 mm expanding the versatility of your zoom lens exponentially. The adapter itself has a 58mm filter thread. Stepping rings are available for other filter sizes.

The Common Thread

In addition to reversing the lens on the camera, NEX-RETRO allows the Sony E-Mount system user to incorporate NOVOFLEX bellows systems for even closer focus and greater magnification ratios.

Highlights

  • Bring to life the finest details: NEX-RETRO allows reverse mounting of Sony E-mount lenses for close focus macro applications.
  • No compromise in flexibility: NEX-RETRO retains complete electronic functionality between Sony E-mount lenses and bodies.
  • Precision engineering: NEX-RETRO is the perfect tool to make the perfect picture even better.

Hasselblad X1D gets electronic shutter and resizable AF points via firmware update

26 Aug

Swedish medium format camera maker Hasselblad has added electronic shutter and resizable AF points to its X1D mirrorless camera via a new firmware update: Version 1.17.2.

The newly added electronic shutter can operate between 68 minutes and 1/10,000sec—extending the short exposure range of the camera from 1/2000sec. It also takes away the vibrations of a mechanical shutter, which should reduce the risk of shutter shock in moderate exposures, and the silent nature of the electronic shutter makes it possible to shoot without disturbing your subject.

These benefits don’t come without some drawbacks, though.

Hasselblad acknowledges that the 300ms it takes the sensor to read from top to bottom could have an impact on the way moving subjects are recorded, and might lead to banding under flickering light sources. ISO will be limited to 3200, and image quality will be slightly lower than in exposures recorded with the mechanical shutter. Finally, continuous drive mode is disabled when using the electronic shutter, as is flash and the camera’s True Exposure feature (as the lens shutter won’t be in use).

In addition to the electronic shutter, the new firmware also adds resizable AF points to the mirrorless medium format X1D—there are now three AF point sizes selectable instead of the single size of the original firmware. The new points measure 4mm, 2.8mm and 2mm, and there are 35 of the largest, 63 of the mid-sized points and 117 of the smallest available to you.

The new firmware is available to download from the Hasselblad website.

Firmware release 1.17.2 for the Hasselblad X1D-50c adds two important features that extend the shooting envelope of the camera: resizable autofocus points, and an electronic shutter function.

By popular demand, three sizes may now be selected offering 35, 63 or 117 points by holding down the AF/MF button and pressing the display [] button to cycle through them. The focus point may be reset to center easily by pressing the X button.

The electronic shutter allows for shutter speeds up to 1/10,000s and is silent, allowing use of the X1D-50c under conditions that require absolute discretion or completely zero vibration. It allows the production of images with extremely high quality in situations that might have previously been challenging – both when silence is needed such as during live performances, or when working handheld in extremely low light conditions. Furthermore, this opens up the possibility to produce adapters for an extended range of lenses beyond the already wide range of native Hasselblad XCD and HC offerings should you have an extremely specific requirement.

User Guide version 1.6 for X1D contains further information for these new functions.

Please note that the electronic shutter has some limitations due to the nature of the current generation of medium format sensors: rolling shutter effects may be present during camera or subject motion; sensor read time is 300ms. Furthermore, under phased light sources (fluorescent, LED) some striping may occur at higher shutter speeds as these sources are not truly continuous.

Hasseblad X1D gets electronic shutter and resizable AF points via firmware update

25 Aug

Swedish medium format camera maker Hasselblad has added electronic shutter and resizable AF points to its X1D mirrorless camera via a new firmware update: Version 1.17.2.

The newly added electronic shutter can operate between 68 minutes and 1/10,000sec—extending the short exposure range of the camera from 1/2000sec. It also takes away the vibrations of a mechanical shutter, which should reduce the risk of shutter shock in moderate exposures, and the silent nature of the electronic shutter makes it possible to shoot without disturbing your subject.

These benefits don’t come without some drawbacks, though.

Hasselblad acknowledges that the 300ms it takes the sensor to read from top to bottom could have an impact on the way moving subjects are recorded, and might lead to banding under flickering light sources. ISO will be limited to 3200, and image quality will be slightly lower than in exposures recorded with the mechanical shutter. Finally, continuous drive mode is disabled when using the electronic shutter, as is flash and the camera’s True Exposure feature (as the lens shutter won’t be in use).

In addition to the electronic shutter, the new firmware also adds resizable AF points to the mirrorless medium format X1D—there are now three AF point sizes selectable instead of the single size of the original firmware. The new points measure 4mm, 2.8mm and 2mm, and there are 35 of the largest, 63 of the mid-sized points and 117 of the smallest available to you.

The new firmware is available to download from the Hasselblad website.
