Sigma 85mm 1: 1.4 DG HSM | A (Art)

The appearance of the Sigma 85mm f / 1.4 DG HSM Art I have been waiting for 4 years. Around the time since the first rumors about its development appeared (hereinafter simply 85 Art). Before that I used Sigma 50mm f / 1.4 DG HSM Art in conjunction with the Canon 7D and was very pleased with the portrait shots. But when I switched to full frame, it turned out that when shooting a person from a short distance, I immodestly highlight the nose as the main advantage of the portrait, with which many disagreed. Especially women. I began to think about a new portrait lens, I wanted to try to make a beautiful portrait, with a shallow depth of field (otherwise why was it spent on a full-frame SLR?). After looking through the mountains of material on portrait lenses, I came to the conclusion that wonderful Canon EF 85mm f / 1.2L II USM I will never buy (indecently expensive), and the lens level Sigma Art 50 need to wait. The cheaper offers from Canon were considered, but here turned up the opportunity to buy a brand new “Helios - 40-2-C"For $ 280, and so I did. (Canon 1.8 / 85 cost three years ago from $ 420 and above - also not cheap).

Helios - 40-2-C and Sigma 85mm 1: 1.4 DG HSM | A (Art)

I am delighted with this lens, and I use it quite often Tair - 11A, also like the picture. Still, I wanted to have an autofocus lens. Evil children do not want to understand that it is necessary to freeze. Stop falling, running, turning your head, etc. The same trouble with adolescents and animals. I already began to look at OLX, for used Canon 135 / 2. But bargaining is hard. The owners of this lens know that the lens is good and does not give in vain. And here they released Tamron SP 85mm f / 1.8 Di VC USD (Model F016). Judging by the tests - the bomb! I started saving money. During this time, Sigma showed at Photokina the new portrait portrait Sigma 85mm f / 1.4 DG HSM A from the Art series. And I thought that I would buy it, I really liked fifty dollars, but they can’t make it worse? Especially since Tamron 85VC by that time, too, had not reached us. It so happened that while the Sigma 85 Art got to American retail, I was already on a flight. But it was lucky that a crew change was planned. A friend bought a lens in the states, through an online store for $ 1050, and brought it to me at the end of December directly to Antarctica. It is completely impossible to send material from there to the network due to the high cost of traffic, so I share my impressions only now, when DxO Mark already tested the lens up and down in its methodology.

So. The lens is larger and heavier than its colleagues (see photo), although it does not look like a monster, like Canon EF 70-200mm f 2.8L IS II USM or other zooms of the same level. Weight is 1130 gr. It's hard to say there. The design is the same as for all lenses in this series, the body is black in special plastic, which almost does not change size when the temperature changes. In a good way, you should check this with a micrometer, but there is no instrument of this size on board. A large rubberized focus ring (5 cm wide) with a travel range of about 135 degrees. This is not 360 degrees, like the Soviet lenses, but not 90 degrees like the Tamron. The ring runs nicely, not tight and not slack, the very golden mean is found. A slight push is felt at the borders of the adjustment range, after which it freely scrolls further. Focusing is internal. The optical scheme of the Sigma 85mm f / 1.4 Art lens consists of 14 elements in 12 groups, including two FLD elements that must match the characteristics of fluorite glass, plus one aspherical element. As for me, the lenses are a bit much, but the lens has absolutely no distortion, according to DxOLab. Probably it cannot be otherwise. Minimum focusing distance = 85 cm.

Sharpening can be easily done only on Nikon, on my Canon I need to switch to manual focus mode. It's good that I got an exact copy, there was no need for this. But if you can use a proprietary USB-dock for fine tuning. The ultrasonic focusing motor is nimble. I tried to measure the focusing speed with a stopwatch from 85 cm to infinity - it turns out garbage, I don't have time to react. Somewhere 0.3 or 0.4 seconds as it seemed to me, but maybe less. The motor is very quiet. When focusing from infinity to 0,85 m, the rear lens goes inward by about 13-14mm - there is a "pronounced" vacuum cleaner effect. In this case, you can easily consider electronic boards (see photo). The manufacturer declares splash and dust resistance and advertisements on page 19 “Popular Photography”January 2017,“ Digital Photo Pro ”01-02 2017, p. 5). However, the instruction manual prohibits using the lens in the rain (?). On the YandexDisk I posted the original scan of the instructions. I can only say that there is a soft rubber ring around the mount. I haven't taken pictures in the rain yet. The hood is normal. While new, it holds up well, but over time, the plastic teeth will wear out, and it will dangle like on mine Sigma 24-105mm f / 4 DG OS HSM A и Sigma 50mm f / 1.4 DG HSM A. For instance Canon EF 16-35mm f / 4L IS USM also a modern lens, it costs a little cheaper, but it comes with a lens hood that has a wonderful spring lock. Why not do it too? Did you save two dollars?

As you can see in the photo, there is a closed focusing scale window with VERY small numbers in meters and feet, which only Hawkeye can easily read. The depth of field scale also complements the composition rather than has a practical meaning - it's tiny. The next item is the AF / AM focus mode switch. Checked - switches.

There is an inscription made in Japan (maybe someone is important). Greenish enlightenment, as on MS Jupiter 37A.

I took pictures of the target so that you can judge the sharpness. The target was printed on a cheap laser printer, so below I will give print quality pictures taken with a macro lens at close range. The target is labeled 600 dpi. This is probably the thickness of the smallest lines. I was unable to maintain an angle of 90 degrees when shooting a target, it is noticeable. Anyone who tried to do the same on the deck of a yacht while rolling - excuse such awkwardness. But all the same, you can form your opinion about the sharpness of these pictures. It can also be seen in the example of angled shots that the purple and green borders have not gone anywhere. In the old lens, they are almost the same, maybe a little more pronounced. I apologize for the monotony of plots, I hope the reason is clear.

I liked the lens. There is nothing sharper in my backpack. Matrices Canon 5D Mark III clearly not enough for him. Judging by the tests of DxOMark.com 36MP Nikon 810 for him is also not the limit.

So now I have a lot of sharpness. This is clearly seen if you enlarge the photo of the chicks. Fluff can be seen in the smallest detail. Now about the picture. The blur zone is very soft on the open aperture, but the bokeh is so correct that it becomes boring. On the other hand, where I set the aperture 4.0, the bokeh seemed harsh. I shot that day on Tair-11A и Helios 40-2-C, everything looks much more interesting there, although the pictures are certainly soapy. Those who are thinking about buying this lens should understand that this is primarily a professional tool from which wedding photographers will apparently be delighted. He has no character of his own, or let’s put it this way.

I took a photo of the New Year's garland so that the circles were visible. So it’s noticeable on them that, starting from aperture values ​​of 2.8-3.2 and further up to 16, “nuts” are clearly visible. Perhaps the reason is this. Maybe I find fault, but I’ll give an example Tair 11A (cheaper) Canon Macro 100 (not a word about highly artistic bokeh) and even Tamron 70-300 for $ 350. Having paid more than a thousand cu I have the right to scold the company for such things.

I really want to see the Sigma 85 A benchmark over time and Tamron 85mm f / 1.8 Di VC USD. That would be interesting. Test from DXOMark goes without live photos. When I looked through tests Tamron 85 f / 1.8 Di VC, I really liked the soft drawing (there were no tests of the Sigma 85 A at that time). It's incorrect to compare photos of different subjects, but from my photos it turns out that Sigma draws harder. Considering that the sharpness of both of these lenses is overkill for my camera, which of the two is better is not an easy question. The “nuts” on the covered diaphragms (see the photo) came as an unpleasant surprise for me, especially since they become too early to be seen. If this is the result of “9 ROUNDED petals”, then I have problems with the perception of round and square.

Sigma 85mm 1: 1.4 DG HSM | A (Art)

Sigma 85mm 1: 1.4 DG HSM | A (Art)

The filter size is 86 mm. Firstly, I did not immediately find it. Not every photo store keeps filters of this size, but about the choice of several manufacturers ...

Secondly, the price for HOYA HMC UV (c), for example - about $ 100. With this money you can Canon EF 50mm 1: 1.8 II buy! But I certainly grumble. To achieve sharpness at this aperture, apparently you need to build a big horseradish. At Zeiss Otus 85 the filter is the same size, but let me remind you - a lens without a focusing motor.

Sigma 85mm 1: 1.4 DG HSM | A (Art)

Sigma 85mm 1: 1.4 DG HSM | A (Art)

So the only serious drawback, I think, is “nuts” with aperture values ​​from 3,2 onwards. For the lens, which Sigma advertises with the slogan “ABSOLUTE” (magazine “Popular Photography 01.2017) and moreover,“ Sublime optical performance at EVERY aperture ”is a serious drawback. Tair-11A cost ten times less, beats him easily on this point. I never cease to be amazed at the greediness of today's marketers and all these managing directors! Well, not engineers save on the number of aperture blades! For modern production, this is not a question. 85% of time and money is spent on making lenses for today's requirements. The diaphragm, probably, goes to the 30th point. Oo-oo-oo-oo-oo-oo-oo-oo!

The rest is rather nitpicking.

Some rigidity and facelessness of the picture? But this must also be compared directly with Tamron and Zeiss. When such a case turns up, it's hard to say. Filter size? But u Zeiss Otus the same 86 mm.

Final World

The lens is outstanding for its price. The fact that he beats in sharpness Carl Zeiss Otus 85mm f / 1.4 (see the Lenstip.com test), but at the same time it has a modern, fast autofocus, and costs four times less, makes you gloat over enough. It gives decent sharpness in the center of the frame already with a full aperture. This ratio of sharpness / quality of bokeh, I have not seen. Blur on open diaphragms is even (sterile can be said). Holds back light well. It does not give geometric distortions. Hard to achieve HA. Of course, the price in the region of $ 1050-1200 for 85 mm is not lifting for most fans. But we are comparing Sigma with the latest Carl Zeiss! Think about it!

The good news is that the price of the previous version SIGMA AF 85 f / 1.4 EX DG HSM will fall now. This is still a good lens that pros and amateurs will want to exchange. It is already being offered on eBay for $ 400, and over time there will be more such offers. The difference between them is small. This is convenient to review at DxOMark.com.

Comments: 118, on the topic: Sigma 85mm 1: 1.4 DG HSM | A (Art). Review from the reader Radozhiva

  • BB

    "Sharpening is easy."
    - still not sharpness, but focusing ...

    • Molchanov Yuri

      focusing is the process of acting on the meaning of an imperfect verb.
      Correct - an action is to perform an action on an action ...
      You completely confused me, probably I should turn to a philologist for clarification.

      • BB

        Focusing is a noun (a completed action is no longer a verb).
        I meant that by rotating the focusing ring you change “focus”, not “sharpness”, because these are slightly different concepts.

        • Molchanov Yuri

          Got it. Thank.

        • kusman

          New rule of the Russian language? Figured it out myself?

    • Alexey

      I agree Zeiss is probably better, but Evtifeev is clearly not impartial. And for most of the readers of this site, I think Zeiss is something virtual because of its price, while Sigma is more real.

      • anonym

        Perhaps ... Helios lost 40-2 to Zeiss! How can Helios 40-2 lose to someone ?!

        • Alexey

          Helios, except for cool bokeh, has nothing to boast of.

          • anonym

            Chromatic is not on open. Absolutely!

            • Molchanov Yuri

              https://yadi.sk/d/t_3qAfiH3GBw8h

              I couldn’t find a place nearby where it was possible to rent cars with low beam, so I can’t check the Evtifeev test. But on Yandex, I posted a photo of the TV tower in Bremerhaven, maybe this will help in the debate about sharpness. I was guided by the operator (the widest part) manually by live view with aperture 1.4.
              Also acted when removing the construction crane. Photo of flowers and some kind of coniferous thing - it checked the bokeh again.

      • Molchanov Yuri

        Zeiss is indeed “virtual” optics for us, most of them have families.
        But such lenses are needed as a record to strive for. And so, after all, Canon, Nikon, and Sigma would have stuck lenses with slight cosmetic changes, because for shareholders it’s just a way to make money, and what's the art?
        But Yevtifeyev, even if not impartial, the test is still interesting. Sigma paints the ruler in my shots. I will try to check the color of the car headlights the day after tomorrow. Most interesting.

      • Molchanov Yuri

        https://www.cameralabs.com/sigma-85mm-f1-4-art-review/3/
        Found a comparison of Zeiss and Sigma on another resource. Zeiss is still better, according to their test.
        Another question is the difference in price ... But Zeiss also positions its products for people whose price is in the third place.

  • Ace

    In the meantime, a fresh 85ki art test rolls over by resolution, to say the least.
    http://www.photozone.de/nikon_ff/1002-sigma85f14artfx?start=1

    • Peter Sh.

      By MVF resolution, this Sigma is better than the similar Nikon 85mm f / 1.4G by a couple of spherical percent in vacuum.
      But pay attention to what invalid result their stopwatch about the legendary Nikon f / 1.4D gossiped to the Germans:

      • Novel

        Photozone measures everything in spherical parrots)

        • Molchanov Yuri

          It's right. On the other hand, comparing the performance of my lenses with the test results on Photozone.de, I can say that everything fits together. The general impression coincides with what these guys write. By the way, it’s very difficult for them to earn a rating of 5 stars. But the tests in the magazines N-Photo and PhotoPlus (Nikon and Canon, respectively) have less confidence.
          By the way, in the March issue of N-Photo they compare Sigma Art 85 with Tamron 1.8 VC - Tamron was the winner there.

          • Novel

            I generally like tamrons a little more, their picture is a little more "warm lamp"))

            As the saying goes, "the taste and color ..."

            • Molchanov Yuri

              And I always liked Tamron and Tokina with some kind of masculine design. Unfortunately, the new line went to unisex, following all the other manufacturers.

          • Peter Sh.

            Well, who is arguing? Only MTF lenses alone cannot be evaluated.
            Moreover, for ultra-wide lenses, for example, such tests are generally not suitable.
            And how can one base a test solely on black and white stripes? We live in the color world, all spectra need to be taken into account.

          • Peter Sh.

            In addition, if you test one hundred copies of the same lens, then the wild spread in MTF and the accuracy of repeated autofocus will generally level all their research.
            The same can be said about the DXOmark tests.

  • Sergei

    Sharp, sharper. And for what? I took nikkor 105 / 2,5 for portraits, all that is needed sharply, and the skin on my face without problems, as if it were retouched. And the background is beautifully blurred.

    • Molchanov Yuri

      I agree with you. I shot and will shoot portraits on Helios-40-2, because I really like the soft drawing. Sharpness Sigma will be needed for shooting animals and children. In the first case, I want to see sharp every hair or fluff, and in the second case, you do not need to worry about skin defects (they are not there at all). But autofocus is there to help. With Helios, I often get beaten by a nut when you take off a child.

  • Gennady

    Thanks for the sensible review.

  • Alexander

    Hello. Faced with the problem of lack of focus in the life view of Sigma lenses on the Nikon D750. Different sigma and carcass are different, so it’s not a question of a specific sample

    • Arkady Shapoval

      Most likely a third-party lens that is unsuccessfully friendly with the D750. Usually it is impossible to cure.

    • Vadim

      This is most likely a camera problem. For me on this model Tokina 16-28 does not work in this mode, but in normal mode.

      • Dmitriy

        This is not a camera problem. This is a compatibility issue. I also have Tokina 16-28 in Live View mode that does not focus on the Nikon D600.

      • anonym

        This is a lens problem, closed carcass protocols, sigma, tokens and other tamrons are forced to do reverse engineering, not always successfully.
        In new lenses, the problem is solved by replacing the firmware, if any, through the docking station.

      • Vadim

        I have all the lenses on Nikon. I noticed on Tamron the quality of focusing in this mode is much worse but focuses. Sigma just did not try this mode because they are for portraits and I see no reason to use it. A type of flower below or from the crowd above so bad.
        I think the compatibility problem should be solved by the camera of course with the developers of the Lenses. Developers can take running lenses for the Test and change the firmware for their own. They just do not want relatives to buy.

    • bigmc

      I also sinned on focusing the Sigma 35 1.4 on Nikon D610 and D750 - only through the viewfinder. I tried to calibrate with the docking station, and introduced an intra-camera correction - continuous confusion and wobbling, focusing every other time, moreover, with artificial light somehow, then with natural light - just tears and soap. As a result, I rolled back the firmware to the factory firmware through the docking station and left this Sigma alone. And today it precipitated when I discovered that this infection with my Nikons focuses through the LP when recognizing a face straight as quickly, clearly and sharply as Nikkors do not focus, and in any light! And with point focusing, it is also quite worthy. Reset all the corrections, try to read the manual into Nikonov's focusing modes for LP, select the desired mode and try to shoot, it suddenly works. I set AF-F (face), aperture 2.8 - it turns out ok.

      • Alexey

        "As a result, I rolled back the firmware to the factory firmware via the docking station"
        Is it possible to roll back the firmware through the docking station?
        About updating is like an irreversible process.

  • Paul

    Bokeh bomb! That's what I love)

  • Vadim

    I can’t find the serial number on it and there is no gold ring.
    As I understand it, the golden ring is a celebration of a quality lens.
    Is this a series for Lovers?

    Can you please tell me if this lens will fit the Nikon d 5000 camera?
    Does it need some kind of adapter?

    • Michael

      No adapters are needed, just a Nikon F version is needed. Focusing problems may occur with this lens.

    Hello! Can you please tell me what you think about the tandem Nikon D5100 + Sigma 85 Art, will it work normally or will there be problems with autofocus? Thanks. And yet, if it does not make it difficult, please advise the lens: a fast 85k with autofocus. We are not talking about the price, but more about correct operation with my camera (Nikon D5100), sharpness, small (or, let's be honest, lower) percentage of HA. What lenses should you pay attention to? Thanks a lot to everyone!
