That lets extra gentle attain the sensor, enabling sooner shutter speeds in low gentle, whereas additionally decreasing depth of subject for higher topic separation.

Sigma 85mm F1.2 DG | Art at a look:

• $1599 / £1299
• 82mm filter thread

Interestingly, Sony doesn’t at present supply an 85mm f/1.2 lens of its personal. Its top-flight choice is the Sony FE 85mm F1.4 GM II, which retails for round £1799. Consequently, at $1599 / £1299, the Sigma provides Sony photographers a bigger most aperture for significantly much less cash, though dimension and weight additionally come into the buying choice.

An 85mm lens is historically a well-liked selection for portrait pictures as a result of it provides a flattering perspective whereas permitting a snug working distance. You can shoot a good head or head-and-shoulders portrait with out crowding your topic, whereas equally, you don’t have to maneuver too far-off to compose a full-length picture.

Adding an f/1.2 most aperture makes the focal size much more enticing for portraits, weddings and social pictures as a result of there’s higher scope to blur a distracting background and draw consideration to your topic. Of course, an aperture that giant additionally means the depth of subject will be extraordinarily shallow, so correct focusing turns into significantly vital.

Features

As a part of Sigma’s Art line, the 85mm F1.2 DG | Art is designed with picture high quality as a precedence. Its optical building of 17 parts in 12 teams consists of two SLD (Special Low Dispersion) glass parts, that are used to manage axial chromatic aberration, together with three aspherical parts that assist right aberrations whereas maintaining the lens comparatively compact.

The focusing system makes use of a floating focus design with two HLA (High-response Linear Actuator) items shifting separate teams. According to Sigma, incorporating an aspherical component into one of many focusing teams creates additional room for the main focus actuator and has helped cut back the general dimension of the lens.

The floating focus system can be designed to minimise focus respiration, which will probably be of specific curiosity to videographers because it reduces the change in framing when the main focus distance shifts.

There’s no optical stabilisation, so the Sigma 85mm F1.2 DG | Art depends on the digicam’s in-body stabilisation the place that’s out there. That’s unlikely to be a serious concern with the present Sony and L-Mount cameras that this lens is designed to accompany.

Sigma has additionally included an aperture ring that may function with distinct clicks or be de-clicked by way of a change for {smooth} adjustment. There are two customisable operate buttons plus an AF/MF change.

The lens has a mud and splash-resistant building, and the entrance component has a water and oil-repellent coating. That’s reassuring for marriage ceremony, occasion and outside photographers who might discover themselves capturing when the climate is lower than good, though, as traditional, climate resistance doesn’t imply the lens is waterproof.

L-Mount customers even have the choice to vary the guide focus ring between linear and non-linear operation with appropriate cameras, with the rotation angle being adjustable between 150 and 720 levels.

Build and Handling

First impressions of the Sigma 85mm F1.2 DG | Art are excellent. From the packaging by means of to the texture of the controls, it’s obvious that this can be a high-quality product. There’s no getting away from the truth that it’s fairly a beefy lens. It’s 87.2mm in diameter and measures 119.7mm in size in L-Mount, or 121.7mm in Sony E-mount. Both variations weigh 905g.

For comparability, the Sony FE 85mm F1.4 GM II weighs 642g and measures 84.7 x 107.3mm. That makes the Sony noticeably lighter and slightly smaller, however in fact it has an f/1.4 slightly than f/1.2 most aperture. The Sigma is 263g heavier than the Sony and 14.4mm longer, which is value taking into account should you’re attempting to maintain your equipment compact.

To be honest, nevertheless, a full-frame 85mm lens with an f/1.2 most aperture was by no means going to be tiny. The Canon RF 85mm F1.2 L USM and Nikon Nikkor Z 85mm f/1.2 S, for instance, each weigh greater than 1kg. According to Sigma, as of September 2026, the 85mm F1.2 DG | Art is the smallest and lightest autofocus 85mm f/1.2 lens out there.

I examined the Sony E-mount model on the Sony A7R VI and whereas the mix is weighty, it feels good within the hand. I’d use a strap if I used to be carrying it for a protracted interval and I’d take into consideration what different lenses I used to be placing in my bag. But I can forgive the Sigma’s bulk due to that f/1.2 aperture.

The broad focusing ring strikes fantastically easily and has a lovely stage of resistance. It falls simply the place I naturally help the lens with my left thumb and index finger, though I can flip it with one finger if I have to.

Closer to the digicam physique, the aperture ring additionally has a stunning really feel. With the clicking mechanism engaged, the clicks are distinct with out being very loud or sticky. Flick the change to the de-clicked place and the motion is super-smooth.

I significantly just like the positioning of the 2 customisable operate buttons. They’re 90 levels aside on the barrel, so one falls conveniently inside attain whether or not you’re capturing in panorama or portrait orientation.

The features out there for these buttons range with the digicam. On the Sony A7R VI, I set them to modify topic detection on and off. I discover that helpful in social conditions once I would possibly wish to change rapidly between photographing folks or animals and inanimate objects with out diving into the digicam menu.

Autofocus

The Sigma 85mm F1.2 DG | Art focuses immediately on a digicam such because the Sony A7R VI. The autofocusing is impressively fast, quiet and decisive, which makes the lens really feel very responsive.

Naturally, it’s appropriate with Sony’s topic detection AF system and that’s an actual bonus for portrait, occasion and social pictures. I used the lens and Sony A7R VI to {photograph} some Reading Festival goers as they began their journeys dwelling and the mix did an important job of discovering a watch within the body, even when my topic was a ways away.

I requested a number of the folks I photographed to hold on with what they have been doing, taking a look at their telephones or chatting slightly than turning in the direction of the digicam. Even with a aspect view of a face, the focusing was proper on the attention.

That’s particularly helpful at f/1.2 as a result of there’s little or no latitude for focusing errors. Having confidence that the digicam and lens will discover a watch means I can focus on the expression, timing and composition slightly than repeatedly checking the main focus.

As you’d anticipate from a premium lens, the guide focusing expertise can be very nice. With the suitable choice chosen within the digicam menu, the world beneath the AF level enlarges as the main focus ring is turned, making exact focusing easy. As I discussed earlier, the ring additionally falls naturally the place I help the lens, so it’s straightforward to make a fast guide adjustment if I have to.

Image high quality

The Sigma 85mm F1.2 DG | Art produces a really spectacular diploma of sharpness throughout the body all through its aperture vary, however I’m particularly impressed by the quantity of element it captures at f/1.2.

You pay a premium for such a big aperture, so it must be good at that setting, and the Sigma 85mm F1.2 DG | Art places a smile in your face. If you seize a head and shoulders portrait, you may anticipate to see sufficient element to inform whether or not your topic is carrying contact lenses. Crucially, I don’t really feel there’s any have to cease down merely to enhance sharpness.

If you select to not use the in-camera or processing correction profile, there’s some vignetting on the widest apertures. It reduces because the aperture closes and is passed by f/2.8. With the corrections utilized, the information look evenly uncovered with no apparent nook shading.

The Sigma lens additionally renders straight strains properly and distortion isn’t one thing that jumps out if you have a look at the photographs. However, switching the correction profile on and off in Adobe Camera Raw produces a slight shift that means it’s correcting a really small quantity of pincushion distortion.

Chromatic aberration can be very effectively managed. I searched round high-contrast edges in my pictures at 100% on display and was unable to search out any apparent examples. I noticed slightly color round a couple of significantly vivid out of focus highlights, however nothing dramatic.

Then there’s the bokeh, which is among the massive causes for getting an 85mm f/1.2 lens. At extensive apertures, out-of-focus areas look splendidly {smooth} and the fall-off in sharpness at f/1.2 is fast. It makes it very straightforward to separate your topic from a busy or distracting background.

Of course, that shallow depth-of-field wants some thought. If you’re photographing a couple of particular person, it’s extraordinarily unlikely that each pairs of eyes will probably be in precisely the identical airplane of focus. There are occasions if you want to withstand the temptation to make use of f/1.2 and cease down slightly to get each topics acceptably sharp.

Most small out-of-focus highlights look excellent, though, as is commonly the case with quick lenses, they grow to be cat’s eye formed away from the centre of the body. Overall, nevertheless, the Sigma 85mm F1.2 DG | Art produces the sleek backgrounds and robust topic separation that I’d hope to see from a lens of this sort.

It’s a considerable lens, and there’s no getting away from the truth that it provides noticeable weight to a digicam bag. However, I discover that simpler to simply accept when the dealing with, focusing efficiency and outcomes are nearly as good as they’re right here. The lens feels reassuringly effectively made, the controls are a pleasure to make use of, and it really works very effectively with Sony’s topic and eye detection.

For Sony photographers, there’s additionally the attraction that Sony itself doesn’t at present supply an 85mm f/1.2 lens.
