Gear of the Year 2017 – Carey’s choice: Sony FE 85mm F1.8

27 Nov
Maybe it’s not everyone’s choice for a ‘landscape’ lens, but I like using the 85mm focal length for just about anything.
Sony a7R II | ISO 100 | 1/320 sec | F8

There are times when I find myself dreaming of a make-believe world where I don’t worry much about camera gear. A world where I’ve simplified, and simplified, until I’m down to the bare minimum of what I think I need to accomplish the sort of photographic work that I like to do.

Obviously, that is not the world that I live in.

Nonetheless, in that carefree fantasy land of plentiful-yet-lucrative corporate jobs, wedding ceremonies and endless travel assignments, I skip like a child with a balloon from gig to gig with two interchangeable lens cameras, and a single lens for each; a fast wide-angle for one camera, and a fast 85mm for the other.

The FE 85mm F1.8 is exactly the sort of 85mm lens I’ve been looking for in Sony’s system since I started at DPReview.

I find the compression and reach of the 85mm focal length – neither of which are too extreme – make it a great contrast for 28mm and 35mm lenses, even just for walking around the city. Also, notice the roundness of those out-of-focus highlights, even at F4.
Sony a7R II | ISO 100 | 1/3200 sec | F4

The Sony FE 85mm F1.8 is an affordable, sharp and lightweight lens for Sony’s full frame E-mount cameras. No, you don’t have to just pick two of those.

On an a7-series camera, the 85mm F1.8 balances beautifully, focuses quickly and is more than sharp enough for the 42MP of the a7R II (or a7R III, for that matter). In Sony’s lens lineup, it sits below the FE 85mm F1.4 GM which is a great lens in its own right, but focuses slower and is far bigger and heavier.

And that’s really the kicker for me with this lens. Sony’s a7-series bodies are usefully more compact than full-frame DSLRs, but often, the lenses can be large and unwieldy. With the 85mm F1.8, you’ve got yourself a truly compact kit.

Though this verbiage is always to be taken with a grain of salt (a flake of snow?) the Sony FE 85mm F1.8 has some degree of weather-sealing.
Sony a7R II | ISO 800 | 1/60 sec | F2.8

So, why 85? In general, I find the 85mm focal length a great complement to 28mm and 35mm lenses. Historically, my most-used gear for shooting events were two Nikon D700s, a 35mm F2D and 85mm F1.8D. I first fell in love with this lens combination on a six-week trip to Nepal during college, photographing endless portraits, landscapes and urban life, and was never left wanting.

With longer lenses, like a 105mm or 135mm, I always feel like I’m backing myself into a corner. And yet, I consistently found that a fast 50 was way too close to 28/35mm to be truly useful as far as getting some variety.

Focusing close to your subject with a wide aperture gives you a nice, dreamy look on the FE 85mm F1.8, while maintaining sharpness at your point of focus.
Sony a7R II | ISO 100 | 1/400 sec | F1.8

But with 85mm, you can move in for a tight head-and-shoulders shot or a decor detail, back up to get a candid of a group interacting, and even with some distance, you can still get background separation if you shoot at a wide enough aperture. Speaking of wide apertures, I rarely use 70-200mm F2.8 zooms because of both their weight, and because I often am shooting at F2 or wider as the lights go down and the reception warms up.

I’ve said this before, but I’m a big fan of gear that ‘gets out of your way.’ For me, the FE 85mm F1.8 does just that. It’s straightforward and has a solid feel. I’ve never felt it’s too heavy, or focuses too slowly, and I can just concentrate on what I’m seeing through the viewfinder. If I were considering a new kit to start out with, a couple of Sony a7-series cameras with the FE 28mm F2 and FE 85mm F1.8 would be on my short list to check out.

Pricing for Sigma 14mm F1.8 DG HSM and 24-70 F2.8 DG OS HSM Art lenses announced, undercuts the competition

24 Jun

Announced in February, two highly anticipated full-frame lenses from Sigma are finally on their way to consumers. Sigma has also announced pricing – the 14mm F1.8 DG HSM will cost $ 1600; the 24-70mm F2.8 Art will cost $ 1300. In both cases, that’s well below the current asking prices for Canon and Nikon versions of similar lenses.

Sigma says the 14mm in Canon and Sigma mount will ship this month, and the Nikon version will be available in July. The 24-70mm will ship for all three mounts this month. Considering there’s not much time left in June, that’s basically now.

Press release

Sigma Begins Shipping Its 14mm F1.8 DG HSM and 24-70mm F2.8 DG OS HSM Art Lenses

The world’s first and only F1.8 ultra wide-angle full-frame lens for DSLR cameras is available now for $ 1,599.00 USD; the new Sigma Global Vision workhorse zoom lens is available now for $ 1,299.00 USD

Ronkonkoma, NY – June 22, 2017 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, announced today the pricing and availability for its new Sigma 14mm F1.8 DG HSM and Sigma 24-70mm F2.8 DG OS HSM Art lenses from its lauded Global Vision line. The ultra-wide angle full-frame 14mm F1.8 Art lens begins shipping in June 2017 for Canon and Sigma camera systems and in July 2017 for Nikon camera systems, for a retail price of $ 1,599.00 USD. The standard zoom full-frame 24-70mm F2.8 Art lens begins shipping in June 2017 for a retail price of $ 1,299 USD.

The Sigma 14mm F1.8 Art, which is the first and only F1.8 ultra wide-angle lens among interchangeable lenses for digital SLRs*, incorporates the same aspherical element as Sigma’s critically acclaimed 12-24mm F4 Art, allowing the lens to deliver a new dimension of visual experience. Boasting outstanding image quality from center to edge, the 14mm F1.8 Art features an 80mm front lens — the world’s largest glass aspherical lens in the industry, offering photographers an ultra-wide prime with virtually no distortion, flare or ghosting. Equipped with a superfast and efficient autofocus system, three FLD (“F” Low Dispersion) elements, and four SLD (Special Low Dispersion) elements to reduce chromatic aberration and coma flare, the 14mm F1.8 Art is suitable for a wide range of photographic needs including astrophotography, architecture and landscape photography.

The 24-70mm F2.8 Art lens, Sigma’s new workhorse standard zoom lens, touts a brand new Optical Stabilizer (OS), Hypersonic Motor (HSM) for highly efficient and fast autofocus, as well as a dust- and splash-proof mount with rubber sealing. The 24-70mm F2.8 Art lens embodies all the technical qualities and finesse that define the high-performance Sigma Global Vision Art series. A popular industry focal range covering a wide array of shooting scenarios, the 24-70mm’s optical design also includes three SLD (Special Low Dispersion) glass elements and four aspherical elements to ensure image accuracy and sharpness. The 24-70mm F2.8 Art aspherical elements use Sigma’s thicker center glass design and highly precise polishing process, delivering stunning images and bokeh effects. The lens’ purpose-built structure boasts a new metal barrel for optimal durability with TSC composite internal moving components designed to resist thermal contraction and expansion.

Both the 14mm F1.8 DG HSM and the 24-70mm F2.8 DG OS HSM Art lenses are available in Canon, Nikon and Sigma mounts. The Sigma and Canon mount lenses work with Sigma’s MC-11 Sony E-mount converter. The Nikon mounts feature the brand new electromagnetic diaphragm.

Sigma 14mm F1.8 DG HSM Art Lens Features and Benefits:

> Sharp, rich image quality

  • Minimized chromatic aberrations: Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help reduce 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.
  • 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 pleasingly softened background. It’s the unique mode of expression that only a large-diameter lens can deliver.
  • 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.

> Offers full-frame coverage

Sigma 24-70mm F2.8 DG HSM OS Art Lens Features and Benefits:

> Superior optical performance

  • Optimal image quality for ultra-high-megapixel DSLRs: This lens offers top performance from the center to the edges of the image thanks to the optical system minimizing 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.
  • Expressive bokeh effect every time: At wide-open aperture, this lens offers outstanding photographic expression. The area in focus is extremely sharp, while the background exhibits a beautiful, creamy 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 artistic circularity.
  • Aspherical Lens Processing Technology: The Sigma 24-70mm F2.8 DG OS 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 OS HSM Art to deliver a very natural and smooth bokeh effect, without the visible concentric rings that afflict typical aspherical lens elements.

> Fast and nimble autofocus photography

  • 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 for exceptionally stable performance.

Sigma Global Vision Line Features & Benefits:

  • Each lens is eligible for user customizable micro-focus and in-home firmware updates with the optional USB Dock and Sigma Optimization Pro software.
  • Each unit is crafted in Aizu, Japan and individually tested for QC and optical performance with the exclusive A1 MTF device.
  • Sigma’s Exclusive Mount Conversion Service allows lenses to be switched between any released mounts (fee-based).
  • Compatible with Sigma Mount Converter MC-11, allowing use of Sigma lenses in Sigma and Canon mounts with the Sony E-mount camera systems.

*As of February 2017

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

22 Jun

In this quick review of the Sigma 135mm f1.8 Art Lens, I will go over some of its features and give you my overall impression of this lens.

Photographers like gear

I belong to several photography groups, both online as well as within my local area, and often times when we meet, we end up talking about our gear. Conversations typically revolve around the gear we have, what we would like to have, and what we want to sell off. On several occasions, I have heard my fellow photographers talk about the Sigma Art series of lenses. They always start the conversation with, “Oh, I absolutely love my Sigma Art lens. The bokeh is so dreamy!” Now, I am a Canon shooter – always have been and always will be. But that does not mean that every once in a while, I don’t like to test out gear from other companies to compare performance, specifications, and price.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The Sigma 135mm F1.8 DG HSM Art Lens comes with a case and a lens hood.

So when I had the opportunity to test out the Sigma 135mm 1.8 DG HSM Art lens, I jumped at the chance. I spent about three weeks with this lens and used it for a variety of photography assignments – both indoors and outdoors. Here is my review based on my personal experiences with this lens.

Technical Specifications

As per Sigma’s website, the Sigma 135mm F1.8 DG HSM Art is a medium range telephoto prime lens designed for modern high-megapixel DSLRs. A new large Hyper Sonic Motor (HSM) delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. This state-of-the-art prime lens touts a dust and splash proof mount for guaranteed performance in any condition and its large 1.8 aperture allows for more creative control over imagery.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The Sigma 135mm F1.8 DG HSM Art Lens attached to my Canon 1V film camera.

My telephoto lens of choice is my Canon EF 70-200L lens. It’s heavy and bulky but gives me some of the best picture quality in its class. Compared to that lens, the 135mm felt lightweight and comfortable to carry around all day. Being a fixed lens, there are no moving parts, unlike the zoom ring on the 70-200mm. While this meant that I had to move around to get shots at various distances, it was not an inconvenience. I just used pretended to have a zoom lens by moving my feet!

The lens looks very sharp and clean. The smooth matte black finish of the lens gives it a certain visual appeal. The build quality is very clean and it feels like a solid piece of glass. The lens is a little heavy (at about 2.56 pounds or 1.2 kg) but if you are used to walking around with other telephoto lenses, it’s not any different compared to using those.

Sharpness of the Sigma 135mm F1.8 Art Lens

The legendary quality of having the dreamiest bokeh is very true with this lens. It is super sharp even when shooting absolutely wide open. I typically shoot very wide opened with all my Canon L-lenses which fits my style of photography. The aperture of f/2.0 is my personal sweet spot – the one that I really trust to give me a shallow depth of field and dreamy bokeh (blurry background). This lens did not disappoint at my favorite f-stop.

But even at f/1.8 (the widest aperture on the Sigma 135mm), the lens was tack sharp with very shallow depth of field. Once it was stopped down to f/16, there was some softness on the edges of the frame but it’s not very prominent. With a lens of this quality, the best aperture would be between f/1.8 to f/4 (in my opinion) to get the best of the shallow depth of field and bokeh that we all love.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

Shot at ISO 200, f/1.8 – wide open – look at that dreamy bokeh.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

ISO 200 at f/2.0

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

ISO 200 at f/9 – more of the entire scene is clear and visible – with a wider (deeper) depth of field here.

Vignetting

The Sigma 135mm at f/1.8 Art Lens showed slight edge vignetting when shot wide open. But for my style of photography, it’s minimal and nothing I could not fix in post-processing. I was very impressed with the number of tack sharp images that I could keep even when I used the lens completely wide open at f/1.8.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

The image above left was shot at ISO 200, f/2.0 and on the right, the same scene was shot at ISO 200, f/9. There is no visible softness or vignetting at either aperture. The bokeh at f/2.0 is so dreamy (shallow depth of field) and at f/9 more of the background is visible.

Autofocus

The Sigma 135mm has an electronic hypersonic motor. This makes the autofocus very fast and smooth. I found that the lens locked focus easily and did not hunt while focusing. The AF motor was also relatively quiet and smooth as compared to other telephoto lenses like the Canon 85mm f/1.2L II USM that is really slow while hunting for focus in the AF mode.

Quick Review of the Sigma 135mm F1.8 DG HSM Art Lens

While hiking my two boys decided they would lead the pack. I really wanted to capture this independent streak and both images are shot less than 2 seconds apart. The Sigma 135mm had no problems tracking focus as they moved up the trail. Both images were shot at ISO 200, f/2.0 and both have the subjects tack sharp and in focus in spite of the movement.

Macro capabilities

While the Sigma 135mm is not described as a macro lens, it did offer 0.2x magnification with a minimum focusing distance of just under three feet. Since I have a dedicated macro lens that I use for my detail shots, I did not pay much attention to this feature. However, in a pinch, this lens could be used to provide some magnification.

Karthika Gupta Memorable Jaunts DPS Article - Sigma 135mm lens review-11

The 135mm zoom was a little tight when I had to take in-studio headshots but once I got the focus locked, it turned out beautifully. Both images were shot at f/2.0 ISO 640, 1/125th.

Summary

Overall I was really very impressed with the Sigma 135mm 1.8 DG HSM Art lens. It is a superbly built piece of gear that was incredibly fast, easy to carry, handle, and use.

The only thing I needed to get used to was the fact that it was a prime lens and not a zoom, unlike my favorite 70-200mm telephoto lens. This meant I had to move around to get shots at different angles and different focal lengths, but I don’t consider that a con. Instead, I feel that shooting with a prime lens makes you more careful and thoughtful about your compositions since you have to physically move around to get a diverse range of shots.

The Sigma 135mm lens is definitely something to look into if you are in the market for a good quality telephoto lens.

Sony FE 85mm F1.8 sample gallery and first impressions

28 Feb

The Sony FE 85mm F1.8 joins Sony’s full-frame E-Mount lineup as the most affordable native lens that offers a short telephoto focal length. Other full-frame systems have had comparably low-cost 85mm lenses for quite a while, and it’s nice to see Sony filling in some of the gaps for budget conscious users.

The FE 85mm balances superbly on Sony’s a7-series bodies, and though it’s no G Master lens, it feels solid enough. Focusing is silent and fairly quick (contrary to Sony’s ‘nifty fifty’ FE 50mm F1.8), and it has excellent sharpness wide open, even well off-center. It’s even sharper by F2.5, seemingly peaking by F4. There’s an awful lot of purple and green fringing wide open though, as you’ll see in our gallery, but this is to be expected, and is indeed common, in lightweight fast primes (they’re far less distracting by F4.5). Careful software corrections might be able to take care of most of it (remember: it’s lateral CA that’s easy to remove, not axial), albeit typically at a cost to other areas of the image – download a few of the Raw files to see for yourself.

On an a7R II, this lens focuses wide open, quickly and accurately.

Of particular interest is our observation that this lens, currently, focuses wide open* on an a7R II (or, technically, opens up to F2 if you’ve selected an aperture smaller than wide open). This addresses one of our largest complaints with recent Sony lens releases that focus stopped down, often slowing focus in low light or forcing otherwise capable phase-detect AF systems to revert to contrast detect-only. It appears that, at least for now, Sony’s recent 100mm STF and 85mm F1.8 lenses address this issue, and without an image cost to boot: take a look at our aperture series with our LensAlign target here (please choose the option to ‘Open Link in New Window’), and you’ll note no focus shift as we stop down (the lens was focused once wide open, then switched to MF for the series). You can also judge problematic apertures for axial CA in this series, as well as how circular out-of-focus highlights remain as you stop down the 9-bladed aperture.

Oddly, the same doesn’t hold true on other Sony bodies: the lens focuses stopped down at the shooting aperture on an a7 II, a7S, and a6300/6500. Oddly, this sometimes leads to slight front-focus at smaller apertures on those cameras, though it’s not a huge deal as the focus shift is often masked by the increased depth-of-field. It’s interesting from an academic standpoint though – as focusing at the selected aperture should increase focus accuracy, not decrease it. We have our hypotheses, but for now, we’ve reached out to Sony for comment.

 *Note this only holds true for AF-S and for initial focus acquisition in AF-C, after which the lens stays stopped down, presumably to avoid having to constantly open and close the aperture during continuous drive. We still wish this weren’t the case, as (1) AF-C is often useful even in Single drive mode, and (2) DSLRs are fully capable of opening and closing the aperture in between shots, even at 14 fps. There may be other nuances we’re missing that explain why Sony chooses to focus stopped down, but the inconsistencies between bodies is confusing. Rest assured, we are in constant discussion with Sony engineers about this issue.
