Review of the Sigma 85mm f/1.4 Art Lens

Review of the Sigma 85mm f/1.4 Art Lens

Portrait sample using the Sigma 85mm f/1.4 Art lens.

Last summer I had the opportunity to test out the Sigma 20mm f/1.4 Art lens and review it for dPS. I absolutely loved the lens, so when the opportunity arose to try Sigma’s 85mm f/1.4 Art lens, I jumped at the chance.

I continue to be excited by Sigma’s lineup of Art lenses, as they offer incredible image quality for a great price. Several of my photographer friends were singing this lens’s praises since it began shipping, so I was eager to see if it lived up to its reputation.

First Impressions of the Sigma 85mm f/1.4 Art Lens

As a Nikon shooter, I tested the Sigma 85mm f/1.4 Art lens in a Nikon mount. The first thing I noticed about this lens is that it is an absolute beast. The lens is 3.7 inches wide by 5 inches long (94.7mm x 126.2mm), and weighs in at a whopping two and a half pounds (1113 g / 39.3 oz.)!  Compare this to Canon’s 85mm f/1.2L II lens, which weighs in at four ounces lighter and is more than an inch and a half shorter. The filter thread is 86mm, compared to 72mm for the Canon one. For another comparison, Nikon’s 85mm f/1.4G is also more than an inch and a half shorter and 2/10 of an inch slimmer, weighs more than a pound less than the Sigma at 595 g / 21oz.), and accepts a 77mm filter.

Specs

The Sigma 85mm f/1.4 Art lens consists of 14 elements in 12 groups, featuring two low dispersion SLD elements and an aspherical element to help reduce chromatic aberration. The construction of the lens feels as solid as other Sigma Art lenses I’ve used. The metal barrel has a nice finished look, the switches and focusing ring have a high quality feel to them and they are easily located when looking through the viewfinder. The ribbed rubber focusing ring takes up a large portion of the lens barrel and provides a long, smooth throw, perfect for manually focusing if you desire.

There is rubber sealing around the lens mount to protect against dust and moisture, as well as oil repellent coatings on the front and rear elements. Sigma also states that the lens’s hypersonic motor (HSM) has 1.3x more torque than its predecessor, allowing the lens to focus faster. Minimum focus distance is 33.3 inches, similar to competitors’ lenses.

Fast glass

The fast maximum aperture of the Sigma 85mm f/1.4 Art makes this lens a workhorse for many applications. At f/1.4, you’re getting a lot of light through the lens and onto the imaging sensor, making it ideal for low light situations. In addition, that fast aperture allows for use of lower ISOs, helping to minimize noise. Finally, working at wider apertures such as f/1.4 mean you can force your viewer to look exactly where you want by creating images with extremely shallow depth of field.

Accessories

The lens ships with a high quality padded soft case, ideal for transporting the lens. Sigma also provides a sizable plastic hood, ideal for helping to eliminate lens flare off the sizable front element. The hood locks into place securely and offers good protection from impact as well.

The Sigma 85mm f/1.4 Art lens is compatible with Sigma’s USB dock, which helps facilitate the updating of firmware, lens calibration, or other customizations such as focus parameters. Unfortunately, I was not provided with the USB dock for this review. My first time shooting with the lens I found it to front focus quite a bit. This was corrected by using my Nikon D810’s AF Fine Tune feature, but in my 25 years in photography, that’s a feature I’ve never had to use before, so I was a little put off by the need to do so.

In Practical Use

Once the AF issues were corrected, the lens was awesome to use. The autofocus was fast and quiet and the lens was tack sharp. The beauty of a portrait lens at f/1.4 is the ability to blur the background way out of focus and have the sharp areas of the image really jump out at you. This made the initial front-focusing issues all the more of a problem because when you photograph using such shallow depth of field if you miss your focus, you really miss it! It’s imperative that you’re precise and that the lens can be counted on to focus where you tell it to.  See this article I wrote: Fast Glass: Tips for Working With Wide Aperture Lenses for more that.

The Sigma 85mm f/1.4 Art is an excellent portrait lens. The bokeh is buttery smooth and the contrast and sharpness make for a beautiful look to the image straight out of the camera. Repeatability of focus was a bit of an issue at times, and I occasionally had to refocus the lens when taking multiple shots at the same distance.  While for me it wasn’t a major problem, it’s worth noting when you may need to work under greater pressure than what I was facing in my test shoots.

Portrait sample with the Sigma 85mm f/1.4 art lens.

Other applications

The lens does exhibit some focus breathing when changing focus from one distance to another. Focus breathing is where objects in the image become more or less magnified as the focus is changed. This won’t be a major problem for still shooters unless you are focus stacking, but for video shooters, this may be a slight cause for concern, especially when doing drastic focus pulls.

While I did not have a chance to use the lens under these circumstances, I was struck by how quickly the lens focused and thought it would have made an excellent lens for photographing sports such as basketball, back in my sports photography days. In addition, the excellent image quality and wide aperture mean the lens can be used in many other situations. Those include; landscape photography, when either a moderate telephoto focal length is needed, or when photographing a flower, tree, or another object when you want a shallow depth of field to blur the background or foreground.

Pros

When properly calibrated, the lens is tack sharp and provides stellar image quality. Build quality is outstanding, and the lens felt good in my hands. The autofocus was fast and smooth, as well as quiet. Image quality was outstanding.

Price-wise, the Sigma 85mm f/1.4 Art lens is a bargain, comparatively speaking. The Nikon 85mm f/1.4G retails for $ 1599, while Canon’s 85mm f/1.2L lists for $ 1899 (at the time of writing this review). At $ 1199, the Sigma provides outstanding image quality at quite a bit less than its competitors. The lens is available in Nikon, Canon, or Sigma mounts.

Portrait sample using the Sigma 85mm f/1.4 Art lens

Cons

This lens is heavy. Combined with a pro body, you could be lifting almost 6 pounds every time you take a shot. For wedding and portrait photographers who might want to use this lens a good portion of their workday, that means a lot of heavy lifting and arm fatigue after a while.

Also, there is no image stabilization on the Sigma 85mm f/1.4 Art. While neither Nikon nor Canon offers image stabilization on their fast 85mm offerings, it should be noted that Tamron’s SP 85mm f/1.8 lens, while a stop slower, does have that feature. That allows the lens to be handheld at shutter speeds slower than could be achieved with the Sigma at 85mm f/1.4.

 

Summary

The Sigma 85mm f/1.4 Art lens is an outstanding value that provides incredible image quality at a good price. While I would prefer it to be a bit small and lighter, there’s no denying that the bottom line for image makers is image quality and the Sigma delivers that. Four stars.

Sigma 14mm F1.8 DG HSM Art pre-production sample gallery

01 Mar

The newly announced Sigma 14mm F1.8 DG HSM Art has the low light shooters on our staff all excited. Super-wide lenses with such fast maximum apertures are rare, and we’ve got high hopes for one with Sigma’s ‘Art’ designation. We jumped all over the chance to take a pre-production version of the lens out for a spin in Yokohama, Japan during CP+ 2017. We’re looking forward to spending more time with the lens, but for now here are some initial samples.

CP+ 2017 – Sigma interview: ‘We’ve learned that some customers require exceptional lens performance’

27 Feb
Kazuto Yamaki, CEO of Sigma Corporation, pictured at CP+ 2017, with Sigma’s new 14mm F1.8.

Sigma released four lenses at this year’s CP+ show in Yokohama – the 14mm F1.8 DG HSM Art, 24-70mm F2.8 DG OS HSM Art, 135mm F1.8 DG HSM Art and 100-400mm F5-6.3 DG OS HSM. We’re at the show, where we made time to sit down with Kazuto Yamaki, CEO of Sigma, to find our more about the new lenses. 


You’ve told me previously that you really want Sigma to make more wideangle lenses. Do you think you’re achieving that goal with the 12-24mm and new 14mm?

Yes, but I’m still not satisfied. I think we need to make more wide-angle lenses. A fast 14mm was one of the lenses that our customers were asking for. Most existing 14mm lenses are F2.8, so F1.8 was a challenge.

The new Sigma 14mm F1.8 is the fastest lens of its kind, and according to Sigma, should outperform competitive, slower designs from other manufacturers.

What have you learned, from making the Art series?

We’ve learned that some customers require exceptional lens performance. We believe that our mission is to make products that other manufacturers don’t have. If we just released similarly-specified lenses to existing models, we wouldn’t be contributing to the industry, or benefiting customers. So our Art series is meant to provide the best performance.

They’re bulky and heavy, it’s true, but our customers like them because of the performance. That’s what we learned.

Hands-on with Sigma MC-11 (CP+ 2016)

You now make a mount adapter for Sony E-mount, but are you planning native support for the Sony E-mount in the future?

Yes, that’s our plan. Our plan is to develop full-frame lenses for Sony E mount, and in the future we will have more E mount lenses. But it takes time. Normally it takes about two years to develop one lens, sometimes three. So even if I start the process now, the lens might come out in two years time.

Sigma’s new Art-series lenses have a degree of weather-sealing – why now?

It’s based on customer demand. Some of our customers said that rain and snow sometimes got into the lens mount, so they wanted sealing. And the other reason is that it’s becoming a trend. Other manufacturers are offering sealed mounts.

Does that make the design process more complex?

No, not really. The only seal is around the lens mount. It’s not a perfect weather-proofing like our Sports series. The 150-600mm for instance has sealing everywhere, on the focus ring and zoom ring.

Of the lenses in the Global Vision line, which were the most complex to bring to market?

Our 12-24mm zoom. Because that lenses uses a very large aspherical element, and at the time, no other company was producing an element of this kind, and there were no machines capable of producing it. So we designed a custom machine to make that element. But as a result of developing that technology, we were able to create this new 14mm F1.8.

The Sigma 12-24mm ultra-wide zoom is a complex design, containing a very large aspherical (front) element.

The Global Vision line is almost five years old. What are you most proud of?

Firstly, I’m still not satisfied. We need to do more. But these days, I’m pretty happy that people regard Sigma as a high-quality company. In the past, some people regarded Sigma as just another third-party lens manufacturer, and maybe even as a cheap, low-quality lens supplier. But people’s perception has been changing, gradually, and I’m very happy about that.

One of the things that professional Canon and Nikon photographers rely on is the support networks for service, like CPS and NPS. Is a professional service support system something that Sigma is interested in creating?

I think we’ll have to. In Japan we’ve already started a pro support project, and I hope we can create a global professional support system very soon.

In the past you’ve expressed concern that you don’t want Sigma to grow too much, too quickly, because this might threaten some the magic of being a small company. Is this something that you’re still worried about?

Growing too fast is not good. We need to grow, but we should grow gradually. We need to develop our capability to produce higher-quality products. That’s the priority. Then turnover, and sales, and profit will follow. We do not prioritize making the company bigger. We focus on product quality, and technology.

Over the past five years, we’ve actually been making fewer lenses, because we decreased the number of cheaper lenses we were producing. But we’ve expanded our manufacturing capacity, because the higher-end lenses use more glass. Cheaper lenses might use 10-15 elements, but these higher quality lenses use 15-20, sometimes even more elements. So more capacity is needed to make a single lens. We’ve actually invested massively in the past five years.

Sigma and Fujifilm have recently introduced lineups of cine lenses. How much growth do you see in this segment?

We don’t know. Even before I decided to get into the cine lens market, I tried to collect market data, but there’s no data out there. It’s not available. It’s only anecdotal. But we guessed that this segment will grow in the future.

Video has lower resolution demands than stills, but we’ve been designing lenses for 36+ megapixel sensors for several years. That is equivalent to 8K, in video terms. A lot of traditional cine lenses aren’t that high resolution. Our lenses might be more affordable, but they’re top quality.

The Sigma Cine lens range includes a geared version of the company’s 18-35mm F1.8, now known as the 18-35mm T2. The lens covers the Super 35 format and requires a roughly 350 degree rotation to zoom from 18-35mm, allowing very precise control.

Do you have a market share target for your cine lenses?

No, we’re waiting to see how the market develops. We can dream, but it’s not the same thing!


Editors’ note:

We always enjoy speaking to Mr Yamaki, partly because on the occasions when we get the opportunity to do so, it’s usually because he’s just unveiled something really interesting. Mostly though, we enjoy speaking to Sigma’s CEO because he’s a nice guy. Open, honest, and candid about Sigma’s plans and ambitions, Mr Yamaki is well-liked in the photography industry, even by his competitors.

Speaking of competitors, I get the feeling that Mr Yamaki was compelled to deliver the new 14mm F1.8 partly out of a general disappointment with the available options for photographers. Sigma has a strong history of innovating in the wide and ultra-wide market, and the new 14mm, alongside the previously-released 12-24mm certainly look like a confident statement of intent. If the 14mm is as good as Mr Yamaki claims (and we are rarely disappointed by the optical performance of Sigma’s Art series) it looks set to be a reference lens for landscape, architectural and astrophotographers. We’re hoping to be able to post a gallery of samples very soon – watch this space.

Also interesting, is another statement of intent – Sigma’s move into affordable cine lenses. While the company is not competing (yet) with the Arris of this world, or with Canon’s Cinema EOS optics, Sigma (like Fujifilm) sees an opportunity to cater to a newer generation of videographers who are working with mirrorless systems. Optically, Sigma’s cine lenses should be top notch, although being based on existing stills lens designs, we’re told that some qualities, such as focus breathing, might cause issues for professional broadcast and film cinematographers. There is a reason, after all, that high-end professional cine lenses can cost tens of thousands of dollars.

So what next for Sigma? We wouldn’t be surprised if Mr Yamaki is working on more wideangle lenses, and following the new 24-70mm F2.8, it seems likely that the company will refresh its 70-200mm F2.8 in the near future, too. More Sony E-mount optics are also on the way, we’re told, which will be welcome news to Sony a7-series users.

Press Release

SIGMA 100-400mm F5-6.3 DG OS HSM

 Introducing the light bazooka-a new approach to the ultra-telephoto zoom

  1. Top performance with the specification and functionality of a more expensive unit
  2. Compact packaging with uncompromising image quality
  3. Push/pull zoom mechanism incorporated
  4. Telephoto plus macro functionality
  5. Other features?

A compact body and top performance in one complete package

An ultra-telephoto lens with an optical stabilizer (OS) system has several advantages. The OS allows the photographer to take photographs in unstable circumstances. The narrow angle of view makes it possible to dramatically compress perspective and flexible handling of the background. The photographer can thereby make the subject appear to jump out of the image, with the area in focus impressively sharp and clear. Nevertheless, ultra-telephoto lenses have traditionally had some disadvantages as well. As the nickname “bazooka” implies, they have tended to be big, heavy, and therefore burdensome to carry around. With the goal of creating an ultra-telephoto lens that is far more accessible, SIGMA incorporated all of its latest technologies into SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary. With its outstanding combination of optical performance and compactness, this is an ultra-telephoto lens that is a joy to carry and use. While keeping the robust functionality and exceptional image quality of an ultra-telephoto zoom lens intact, SIGMA has achieved amazingly compact packaging enclosing 400mm optics. Introducing the new and greatly enhanced “light bazooka” ultra-telephoto zoom lens.

SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary offers the compact size, lightweight, and high cost performance of a 70-300mm lens while delivering 400mm telephoto performance. This approach results in a tempting new ultra-telephoto choice for photographers. Offering a combination of stunning image quality and outstanding functionality, this lens satisfies the needs of pros and amateurs alike.

?Key features?

  1. Top performance with the specification and functionality of a more expensive unit

Since its release, the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary has won photographers over with its strong fundamental performance and exceptional image quality. The new lens retains all of this performance in a compact 400mm ultra-telephoto zoom package with a filter size of just ?67mm and weight of just 1,160g. Yet it also comes with the full range of features and functions expected of an ultra-telephoto zoom: optical stabilizer (OS), hypersonic motor (HSM) with updated algorithm for fast autofocus, focus limiter, and more. In addition, this uncompromising specification becomes customizable with the available SIGMA USB Dock accessory.

  1. Compact packaging with uncompromising image quality

In designing this lens, SIGMA strived to push both compactness and image quality to the limit. Four SLD (Special Low Dispersion) glass lens elements and an optimized power distribution help minimize optical aberrations. Moreover, by taking special care to minimize transverse chromatic aberration, which cannot be corrected via aperture control, SIGMA has ensured outstanding image quality throughout the zoom range. 

  1. Push/pull zoom mechanism incorporated

For quick control of the angle of view, the zoom ring incorporates a push/pull mechanism in addition to the regular twist mechanism. The exclusive lens hood has also been designed to accommodate push/pull zooming and overall lens maneuverability. By making it possible to adjust the angle of view instantly, this lens gives photographers an even better chance of getting that crucial shot.

  1. Telephoto plus macro functionality

With a minimum shooting distance of 160cm and a maximum magnification ratio of 1:3.8, this lens can shoot either from a distance or up close. 

  1. Other features
  • Dust- and splash-proof mount

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind.

  • All-new optical stabilizer (OS) unit with exclusive algorithm

Featuring a newly developed gyroscopic sensor and a new and exclusive algorithm, the all-new OS unit provides a powerful stabilization effect. An acceleration sensor detects camera shake in any direction—horizontal, vertical, or diagonal. This technology allows the OS to stabilize the image very effectively, regardless of whether the camera is being held in horizontal or vertical orientation.

  • Nikon electromagnetic diaphragm mechanism included

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

Note: Functionality may be limited on some camera bodies. 

  • Rounded diaphragm 
  • Designed to minimize flare and ghosting
  • Compatible with the newly developed tele converters
  • Fast AF with full-time manual override

Note: The operation of full-time MF may vary based on mount type

  • Compatible with Mount Converter MC-11
  • Available SIGMA USB DOCK (Makes customization and flexible adjustment possible)
  • Available Mount Conversion Service (Allows use with another camera body)

Sigma announces 14mm F1.8, 24-70mm F2.8 and 135mm F1.8 Art lenses

21 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_7013646430″,”galleryId”:”7013646430″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Sigma has released a trio of its high-end ‘Art’ lenses: two primes and one zoom. All three are designed for full-frame Canon, Nikon and Sigma bodies.

The first is the ultra-wide 14mm F1.8 DG HSM, which Sigma claims is the ‘world’s first and only F1.8 ultra-wide-angle lens.’  The lens has 16 elements, three of which are FLD (low dispersion) and four are SLD (super-low-dispersion). It also has a large (80mm) aspherical front element to reduce distortion and ‘deliver outstanding image quality from the center to the edges.’ The 14mm F1.8 has 9 rounded aperture blades, a minimum focus distance of 27cm/11in and a ring-type ultrasonic (HSM) focus motor.

Next up is the Sigma 24-70mm F2.8 DG OS HSM Art. This lens features three SLD and four aspherical, nine rounded aperture blades and optical image stabilization. The lens is weather-sealed and made of a combination of metal and ‘thermally stable composite’ material. The minimum focus distance of the 24-70 is 37cm/1.5in and it uses 82mm filters.

Last, but certainly not least, is the 135mm F1.8 DG HSM telephoto prime. Sigma says that this lens ‘offers the […] resolution required for 50MP or higher ultra-high-megapixel DSLRs.’ It has a hypersonic (ring-type ultrasonic) focus motor that delivers fast (and ‘exceptionally stable’) focus speeds, while an acceleration sensor ‘detects the orientation of the lens’ so the AF system can respond to ‘varying loads on the focusing group due to gravity.’

The lens has 9 rounded aperture blades, dust and splashproof construction, and a weight of 1130g/40.2oz.

Pricing and availability for all three lenses will be announced at a date to be determined.

Press Releases:

SIGMA 14mm F1.8 DG HSM
Introducing the world’s first and only* F1.8 ultra-wide-angle lens

A true high-speed lens that delivers a new dimension of visual experience

*Among interchangeable lens for digital SLRs as of February 2017

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience
  2. Seventh 35mm full-frame prime lens to join the Art line
  3. Other features 

A true high-speed lens that delivers a new dimension of visual experience

In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, F2 barrier-breaking F1.8, the SIGMA 14mm F1.8 DG HSM | Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering F1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.

?Key features?

  1. 14mm ultra-wide angle of view and F1.8 brightness deliver a new dimension of visual experience

By leveraging its extreme angle of view and the dramatic perspective this creates, an ultra-wide-angle lens can get up close and personal with a subject while at the same time taking in a vast background—an example of photography going beyond normal human vision.

SIGMA 14mm F1.8 DG HSM | Art combines the extremely deep depth of field that comes from an ultra-wide angle of view with the extremely shallow depth of field that comes from F1.8 brightness. The result is a sharply captured subject set against a vast background dramatically blurred with a beautiful bokeh effect. It is a highly impressive mode of photographic expression that until now simply has not existed.

  • Minimized chromatic aberrations

Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. The result is outstanding image quality from the center of the image to the edges.

  • Featuring a large-diameter aspherical lens element

The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large ?80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ?80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm F1.8 specification—the first of its kind.

  • Minimized distortion

Serving as the front lens element, the large ?80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

  • Distinctive bokeh effect

Even at the 14mm ultra-wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver. 

  1. Seventh 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 14mm F1.8 DG HSM | Art is the seventh prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.

  1. Other features

SIGMA 24-70mm F2.8 DG OS HSM
Top-level performance optimized for the era of ultra-high-megapixel cameras

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras
  2. OS functionality and newly designed HSM for success on any shoot
  3. Lens barrel designed for high rigidity
  4. Other features?

The definitive large-diameter standard zoom lens for any shoot

What photographers demand from the 24-70mm F2.8 specification is much more than outstanding image quality. They want all the features that make this a go-to lens for a wide range of photographic opportunities, including optical design ideal for the latest ultra-high-megapixel digital cameras, hypersonic motor (HSM) for high-speed autofocus, optical stabilizer (OS) with powerful stabilization effect, dust- and splash-proof mount with rubber sealing, and a metal barrel for a stable, rigid feel. This all-new 24-70mm F2.8 lens from SIGMA delivers the performance and functionality that help pros succeed in news, nature, and many other fields of photography.

?Key features?

  1. The large-diameter standard zoom ideal for today’s ultra-high-megapixel digital cameras 
  • Outstanding optical performance

Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements help minimize optical aberrations. To ensure outstanding image quality from the center to the edges of the photograph, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control, The optical system also minimizes distortion, which can be particularly evident in wide-angle shots, resulting in excellent optical performance throughout the zoom range.

  • A 24-70mm F2.8 lens that meets the high standards of the Art line

SIGMA has continuously pioneered 24-70mm F2.8 lenses that are a step ahead of the times. The first model of this specification, SIGMA 24-70mm F2.8 EX DG ASPHERICAL DF, launched in 2001. Representing the fourth generation of the family, the new SIGMA 24-70mm F2.8 DG OS HSM | Art accomplishes a challenging feat in optical design: incorporating optical stabilizer functionality in a large-diameter standard zoom. By leveraging all of its design and manufacturing expertise, SIGMA has ensured that this new lens fulfills the uncompromising requirements of the Art line for image and build quality.

  • Bokeh that is a cut above

At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful bokeh effect with only slight spherical aberration. Since large-diameter zoom lenses are often used at wide-open aperture, SIGMA has paid close attention to the shape of the bokeh, aiming for perfect circularity. 

  • Incorporating advanced aspherical lens processing technology

Aspherical lenses necessitate refined expertise in the design and manufacturing of advanced, high-performance lenses. SIGMA’s first products to feature this technology were the SIGMA 12-24mm F4 DG HSM | Art and SIGMA 14mm F1.8 DG HSM | Art, which both incorporated a large ?80mm aspherical lens as their front lens element. Building on the success of these predecessors, the SIGMA 24-70mm F2.8 DG HSM | Art incorporates an aspherical lens element that helps achieve extremely high resolution. This element is much thicker at the center than the edges, and forming its unusual shape is a feat of manufacturing technology. Moreover, SIGMA processes the surface of this aspherical lens element with ultra-precise tolerances that are measured in hundredths of a micrometer. This extremely fine surface allows the SIGMA 24-70mm F2.8 DG HSM | Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

  1. OS functionality and newly designed HSM for success on any shoot

Designed for advanced utility in a wide variety of situations, the optical stabilizer (OS) offers a powerful stabilization effect. The newly designed large hypersonic motor (HSM) offers 1.3 times the torque of its predecessor and exceptionally stable performance even at lower speeds.

* Based on CIPA’s guideline. Measuring at telephoto end, when it is attached to the camera with 35mm image sensor.

  1. Lens barrel designed for high rigidity

Since large-diameter standard zoom lenses tend to serve as a go-to lens and see frequent use, the SIGMA 24-70mm F2.8 DG HSM | Art is designed to stand up to the challenging shooting environments that pros encounter. To this end, the lens barrel contains a large amount of metal, while the external moving parts feature thermally stable composite (TSC), which is resistant to thermal expansion and contraction. This structure contributes not only to the outstanding optical performance of the lens but also to its high rigidity and confidence-inspiring build quality.

  1. Other features
  • Mount with dust- and splash-proof design

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing helps provide peace of mind. In addition, the front lens element features a water- and oil-repellent coating that helps the lens perform well in the rain, near water, and in other challenging conditions.

  • Nikon electromagnetic diaphragm mechanism included

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.

Note: Functionality may be limited on some camera bodies.

  • Fast AF with full-time manual focus
  • Compatible with Mount Converter MC-11
  • Available SIGMA USB DOCK (Makes customization and flexible adjustment possible)
  • Available Mount Conversion Service (Allows use with another camera body)
  • Rounded diaphragm
  • Designed to minimize flare and ghosting
  • High-precision, durable brass bayonet mount
  • Evaluation with SIGMA’s own MTF measuring system “A1”
  • Made in Japan (With outstanding craftsmanship)
  • The lens barrel is engraved with the year of release

SIGMA 135mm F1.8 DG HSM
With F1.8 brightness, this telephoto lens for full-frame cameras further strengthens the Art line’s prime options

  1. The ultimate 135mm telephoto designed to prioritize optical performance
  2. Fast and nimble autofocus photography
  3. Sixth 35mm full-frame prime lens to join the Art line
  4. Other features? 

Introducing the ultimate 135mm telephoto featuring top-level performance

135mm telephoto lenses are often categorized as the foundational telephoto, the first one to add to a lens collection. This focal length delivers a strong perspective compression effect, while the large diameter with F1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM | Art makes this bokeh effect not only impressive but also beautiful while delivering superb contrast and sharp image quality in every shot. It offers the outstanding resolution required for 50MP or higher ultra-high-megapixel DSLRs. By incorporating its latest innovations in design and optical glass and rethinking every aspect of the lens, SIGMA has ensured outstanding image quality all the way to the edges, establishing the new standard in 135mm telephoto lenses.

With resolution so crystal-clear that individual hairs can be discerned in a portrait, this large-diameter lens also delivers a beautiful bokeh effect, giving photographers everything they need. It is ideal for close-ups and full-body shots, with subjects standing out against a pleasantly blurred background. In addition to standard portraits, including bridal shots, this lens is a top performer for live events, with its super-fast autofocus capturing subjects with ease.

?Key features?

  1. The ultimate 135mm telephoto designed to prioritize optical performance
  • Image quality optimal for ultra-high-megapixel DSLRs

To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel DSLRs, the focus mechanism features SIGMA’s floating system. No matter what the distance from the subject, this lens offers top performance from the center to the edges of the image. By minimizing distortion as well, the lens delivers impeccable image quality—no need for digital adjustment during image processing.

  • Ideal for portraits requiring a dramatic bokeh effect

The 135mm focal length delivers a stunning compression effect: even fairly close to the subject, the telephoto ring allows the photographer to establish a variety of dramatic perspectives. The compression effect truly shines in both close-ups and full-length portraits, making composition easy. Moreover, the large diameter with F1.8 brightness makes possible a body shot with an impressive bokeh background. In sum, this lens puts a full menu of compositional options at the photographer’s fingertips.

  1. Fast and nimble autofocus photography

The large hypersonic motor (HSM) offers two benefits. It delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. The acceleration sensor detects the orientation of the lens, allowing the autofocus system to respond to varying loads on the focusing group due to gravity. Along with the optimized AF algorithm, these features deliver fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.

  1. Sixth 35mm full-frame prime lens to join the Art line

Launched in 2012, the SIGMA 35mm F1.4 DG HSM | Art was the first lens in the Art line. Since then, SIGMA has developed a wide variety of lenses for the line, and the SIGMA 135mm F1.8 DG HSM?Art is the sixth prime lens in the line to offer 35mm full-frame coverage. Now even stronger, the Art line sets the new standard for prime lenses in the ultra-high-megapixel era.

Has a new champion been crowned? Sigma 85mm F1.4 Art lens review

08 Feb

The Sigma 85mm F1.4 Art hasn’t been on the market long, but it has already begun to make some serious waves. Lenstip and DxO have rated it the sharpest 85mm lens ever created, beating out even the legendary 85mm F1.4 Zeiss Otus, which isn’t something that we take lightly. We were lucky enough to get our hands on the lens back in mid-November and we were very impressed to say the least, so much so that it took top honors for the ‘Best Prime Lens of 2016’ as chosen by our staff.

It has, without a doubt, been a pretty big topic of discussion not only amongst our staff members, but also amongst portrait photographers around the world. With that said we just had to get our hands on it to see how it really performs and to see how it holds up next to some very stiff competition at 85mm. The Sony FE 85mm F1.4 GM is a very formidable competitor and arguably the best modern 85mm F1.4 on the market (behind the manual focus Zeiss Otus, of course). With that in mind, the question is; can the Sigma hold its own? Our review will answer that question and more.

APS-C   

With an equivalent focal length of 136mm and an equivalent aperture of F2.2, this lens can be usefully used on an APS-C camera. Even with its slightly longer focal length, it does still fit into the focal range that’s often used by portrait photographers and the fast aperture does allow for it to be used in low-light situations as well. However, its size, weight and price makes it worth considering 85mm F1.8 lenses instead.

Sigma 85mm F1.4 DG HSM Art headline features

  • F1.4 maximum aperture
  • 85mm max fixed focal range
  • 2 FLD glass elements (low-distortion glass with fluorite-like performance)
  • 1 Aspherical SLD element
  • Canon EF, Nikon (FX) and Sigma SA Bayonet mounts

Dimensions  108 mm (4.23?) x 90mm (3.52?) 126mm (5.0″) x 95mm (3.7″)
Hood  Yes ( ALC-SH142) Yes

As you can see the lenses are fairly different in terms of build and design. The Sony 85mm has a manual aperture ring that can not only function on its own, but the aperture can also be adjusted with the camera by switching the ring to ‘A’. This ring also features a special de-click feature for smooth, silent aperture changes while shooting video. The Sigma 85mm lacks the weather sealing that the Sony has and there’s also a fairly substantial difference in size and weight as the Sony 85mm is a fair bit smaller and lighter. The price point is one area of the where the Sigma really prevails over the Sony, on paper, at least.

Specifications are fun to look at, but the real question is how do these lenses perform? Read on, to find out.

Sigma 85mm F1.4 Art DxO results: a new king is crowned

03 Feb

$ (document).ready(function() { LensWidget({“containerElement”:”#reviewLensWidget”,”allowProductChange”:false,”enableKeyboardShortcuts”:false,”state”:{“lensId”:”sigma_85_1p4_dg_hsm_a”,”cameraId”:”nikon_d810″,”version”:”0″,”view”:null,”aperture”:null,”focalLength”:null}}) })

DxO just published its score for the Nikon mount Sigma 85mm F1.4 DG HSM A. Drumroll please: it received the highest score ever for a lens on DxO, a 50 when mounted to a D810 and a 51 when mounted to the D800E. What’s even more impressive is that it actually scored a perfect 36 P-Mpix for image sharpness on a D810, which has a 36MP sensor.

That’s pretty incredible. We know that sharpness isn’t everything when it comes to shooting portraits, but you have to admire the sheer feat of engineering that Sigma was able to accomplish with this lens.
