In the review, I will call the Sigma 19mm 1: 2.8 DN A (ART) lens in abbreviated form - Sigma 19 / 2.8 Art.

This review shows the lens version for Sony cameras with mount Sony E (APS-C). But Sigma 19 / 2.8 Art also available for Micro 4/3 mirrorless cameras.

It's important: there is a similar older lens Sigma 19mm 1: 2.8 EX DN.

In short

The Sigma 19 / 2.8 Art is a wide-angle lens for mirrorless cameras with Sony E mount and Micro 4/3 mount. It has a low price tag, compact size, fast focusing motor and good optical performance. Of the obvious shortcomings, I can highlight the weak resolution in the corners and edges of the frame at F / 2.8 and the dirty focusing ring.

The Sigma 19 / 2.8 Art is one of the most affordable lenses in the Sigma Art line. At the time of announcement, the lens was priced at just $ 199.

Sigma 19 / 2.8 Art is a good alternative for original Sony E 2.8 / 16  и Sony E 2.8 / 20.

History

January 10 2012 the lens was introduced Sigma 19mm 1: 2.8 EX DN for Sony E, Micro 4/3 mounts.

January 29 2013 the Sigma 19 / 2.8 Art lens (from this review) for Sony E, Micro 4/3 mounts was presented.

Very important! Lenses Sigma 19mm 1: 2.8 EX DN and Sigma 19 / 2.8 Art use the same optical design, the same MTF graphs, have the same minimum focusing distance, number of aperture blades, etc. In fact, the Sigma 19 / 2.8 Art is a simple upgrade from an older Sigma 19mm 1: 2.8 EX DN.

Assembly

Assembled only in Japan.

The Sigma 19 / 2.8 Art is small and lightweight, perfect for Sony NEX / Alpha and Micro 4/3 compact mirrorless cameras. True, for example, the original pancakes for Sony E - Sony E 2.8 / 16  и Sony E 2.8 / 20 much smaller Sigma 19 / 2.8 Art.

The lens uses small 46mm filters. The Sigma 19 / 2.8 Art is one of the smallest lenses in the Sigma ART series. For the dimensions of some of the other Sigma ART lenses I have prepared small video on your Youtube channel.

The focusing ring does not have a rubber insert, it is wide, glossy, and easily gets dirty. The part of the lens closer to the mount is more matte. At first it is difficult to know if the Sigma 19 / 2.8 Art has a focus ring at all.

Lens uses metal bayonet, but not weatherproof.

On the body there is only a bayonet mount mark and a mark for quick installation of the hood. The lens uses a small plastic hood that locks into grooves near the front lens of the lens. The hood can be installed in the opposite direction for transportation. The hood has a grooved ring that makes it easier to manipulate.

The diaphragm consists of 7 blades; at all aperture values, a fairly round aperture is obtained.

Overall build quality is at a high level.

It's important: Sigma 19 / 2.8 Art is available in black and silver body colors.

Focusing

To focus, the lens uses a special linear focus motor.

Very important: parts of the linear motor, and possibly the inner lens group, which is responsible for focusing, hang freely on the off camera (or without it at all). There may be an impression that something is broken in the lens. It looks like loose lens dangling some Sigma lenses with a built-in image stabilizer, where the stabilizing lens group is not suspended in the magnetic field when the camera is turned off and also dangles freely. But as soon as you turn on the camera, in the middle of the Sigma 19 / 2.8 Art the knocking disappears. This is normal behavior.

The motor is very quiet during autofocus. Auto focus speed is fast. The focusing speed is sufficient for comfortable work in most photographic tasks.

With a camera Sony a3500 there were no problems with focusing. The lens worked quickly and accurately. Only in the most difficult situations the camera could not perform the correct focusing.

It's important: The focusing speed depends very much on the camera used. For example, with a budget camera Sony a3500 this lens focuses quickly but is very uncertain due to the contrast-only focusing method.

The focusing ring is electronic, in manual focusing mode it rotates very smoothly and for a long time, it is very difficult to determine the angle of rotation that performs focusing from MDF to infinity. It is convenient to aim manually. In auto focus mode, the focus ring does not rotate and you can hold the lens by it.

Lens has internal focus, the front lens remains stationary during focusing. Optical design and focusing are designed to avoid loss of image quality at different focusing distances. You can use all kinds of filters without any problems.

The closest focusing distance is only 20cm and the maximum zoom ratio is 1: 7.4, which is quite good for a wide-angle lens.

Lens supports continuous manual focus control (Full-Time Manual Focus).

Focus Features:

  1. No lens barrel focus mode switch... Switching should be performed via the camera menu or camera controls.
  2. There are no useful cues like focusing distance. You don't even know in which direction to rotate the focusing ring to focus towards MDF or infinity.
  3. Important: The quality of focusing work of Sigma 19 / 2.8 Art strongly depends on the camera used, as well as on the system used for which the lens is made.
  4. The Sigma 19 / 2.8 Art has a slight 'Focus Breathing' effect (changing the angle of view while focusing). When focusing towards the MDF, the angle of view decreases.
  5. Focus Shift (focus shift, changing focus distance due to iris)
  6. Important: The Sigma 19 / 2.8 Art is a third party lens. It may happen that it will not work correctly with some cameras.

Image quality

The Sigma 19 / 2.8 Art was released in early 2013, when there were already 24 MP APS-C cameras on sale, and therefore, most likely, the lens was immediately designed to work on sensors with a high pixel density. 20 megapixels on my cropped camera with APS-C sensor does not cause any particular problems.

The Sigma 19 / 2.8 Art exhibits moderate optical imperfections. There are chromatic aberrationthat are significant at the edges of the frame. There is also vignetting around one stop at F / 2.8, as well as a little distortion. In the center of the frame at F / 2.8 the lens is very sharp, but in the corners of the frame on APS-C the situation is not good. Overall edges and corners are better than original Sony E 2.8 / 16... Most likely, there will be no significant problems in the corners of the frame on Micro 4/3 cameras. At closed apertures, the lens produces a very sharp image as expected, practically over the entire field of the frame.

Many reviews of this lens have been carried out with the Micro 4/3 family cameras, where it performed better than APS-C (less problems in corners and edges at F / 2.8, less vignetting, aberrations at the edges are not so noticeable).

The Sigma 19 / 2.8 Art has a lens profile in popular RAW converters, which makes it easy to automatically correct some distortions.

My experience

Sigma 19 / 2.8 Art was on my review for a short time and even during the autumn bad weather, so I did not have time to shoot many shots with this lens.

Typically, all ART lenses have their own unique optical design, which was calculated precisely taking into account the high requirements of the Sigma Art line. But the Sigma 19 / 2.8 Art uses the optical design of the older Sigma EX series lens. It turns out that the Sigma 19 / 2.8 Art is not a real 'ART lens'. In general, all three Sigma ART DC 19 / 2.8 lenses, 30/2.8, 60/2.8 very different from their fellows. They have a completely different case design, and still only Sigma ART DC 19 / 2.8, 30/2.8, 60/2.8 use f / 2.8, while all other Sigma ART fixes, except the Sigma ART MACRO, have a much larger maximum aperture, which usually ranges from F / 1.2 to F / 1.8.

Overall a more compact pancake lens Sony E 2.8 / 16 I liked it more.

So far, this is the weakest lens in the Sigma Art line that I have shot. But weak does not mean bad. In general, I would not put the 'ART' mark on this lens.

In general, I got the impression that the lenses Sigma ART DC 19 / 2.8, 30/2.8, 60/2.8 got into this line by accident, and instead of them there should be three lenses with a similar focal length Sigma Contemporary DC DN 16/1.4, 30/1.4, 56/1.4.

And I also have a question: why Sigma lenses 16/1.4, 30/1.4, 56/1.4 in their name they are marked DC DN (DC - for crop, DN - for mirrorless), at the same time Sigma 19 / 2.8 lenses, 30/2.8, 60/2.8 in their name they have only the DN marking.

Comments: 34, on the topic: Review of Sigma 19mm 1: 2.8 DN A (ART)

  • Rodion

    Why is it better than the SEL 16 / 2.8?

    • Arkady Shapoval

      it is better in the corners, at 16 2.8 everything is worse

      • Victor

        “16 2.8 is getting worse”

        “Overall, I liked the more compact Sony E 2.8 / 16 pancake lens better.”

        Um ... :)

        • Rodion

          The pancake is wider, more pancake and 4 times cheaper on the secondary.

          • Victor

            At local flea markets, only doubled - 16 / 2.8 about 50 dollars, 19 - about a hundred in equivalent.

            But I'm not sure that 16 / 2.8 is only twice as bad)) Its angles are really weak. And in general, the resolution does not shine, frankly.

        • Arkady Shapoval

          It's also compact and wider and cheaper. Optical quality is not the only criterion.

          • Victor

            Then it would be worth clarifying that in the review the lenses are compared not only in optical quality :)

            I looked at the samples more closely, yes, 16 in the corners on the open is significantly inferior to this sigma, and can really take up only for its price and compactness. In general, I was extremely surprised, but 16 at slightly covered up to f / 3.5 is even inferior to the standard Nikon kit 18-55VRII at 18mm and the same f / 3.5, and the relative leveling of sharpness across the field occurs already somewhere at f / 8.

            • Arkady Shapoval

              What to clarify? What I liked more 16 mm, what is written in the section my experience? This is my personal experience, I can write any subjective stuff in this section. In other places, I tried to indicate the objective differences

              • Victor

                Clarify that “I liked one more than the other” not only in terms of optical quality (which is implied by default in any review, and no matter what section it is), but also because, for example, it is much cheaper, otherwise it can be misleading.

                Well, the master is the master.

              • Arkady Shapoval

                and he told me overall I liked more what, in fact, is written in black and white in the text, and what was actually meant. But once again - this is my personal impression, it shouldn't bother anyone, since it has the most mediated relation to objective reality.

  • Anatoly

    Sigma has already discontinued the entire range of 19, 30, 60 mm, but you can still get new ones on ebay. Personally, I liked 60 / 2,8 the most of them, per-pixel sharpness is already given with the open one. The weak point for all three is resistance to the counter (especially true for 19). Ugly green translucent hares for half a frame ruined a lot of these same frames for me)

    • Jankowsky

      I have 19 and 60mm. I use them on NEX 3N, a5000, a3500. 60 \ 2.8 is actually something phenomenal, how they were able to make such a budget cheap small but brutal "plug", which buries in sharpness in general EVERYTHING, including Zeiss, expensive L-ki and Nikon zooms on this focal length, nothing sharper and smoother for Sony E do not know and probably will not see. At the same time, in addition to sharpness, it has absolutely perfect geometry, so much so that even with automatic mixing of a huge panorama, nothing needs to be edited at all!

      • Dim

        I have just 60 / 2,8 - I don’t know why, but it didn’t take root with me on the a5000, either the focal inconvenient, or something else. Directly excellent sharpness I did not see or an interesting drawing. For me, Chinese lenses for video surveillance through an adapter are much more interesting. Now the camera is equipped with a Nikkor 50 / 1.8 through a speed booster - and the focal point is more convenient, the sharpness is much greater and the picture is more interesting. But this, of course, is all taste.

  • Classic

    And where did you get what DN means for cropped cameras, there is not a word about this on the Sigma website. But there is a designation DG, DC, which just means crop and full frame.

    • Classic

      SIGMA lenses with “DC” in the name are designed for cameras with APS-C image sensors, and SIGMA lenses with “DG” in the name are designed for cameras with full-frame sensors.

      • Novel

        They produced DG and DC lenses for full frame and cropped DSLRs, respectively. Then a separate DN series for mirrorless cameras, which at that time were only cropped. And with the release of full-frame sleepers, we had to differentiate between DG DN and DC DN.

        • Classic

          Anyway, there is a mistake in the text, because DN does not mean that the lens is for crop.

          • Novel

            “DN (Digital Neo) is a lens designed for mirrorless cameras with a cropped sensor” - strictly speaking, this is the correct wording. For those who are especially picky, you can specify: DN (also DC DN) - blah blah - (unlike DG DNs, designed for mirrorless full-frame cameras), but it's too boring.

            • Victor

              +1

              The specified wording is more than enough, as for me, since sigma has already managed to introduce some confusion into the notation (without adding the letter “DC” immediately when the first models were released), and therefore the only designation “DN” on the lens (without adding DG) is already implies that the lens is specifically for a mirrorless cropped camera, and nothing else.

    • Victor

      In turn, where did you get the idea that the text declares the relationship of the abbreviation DN to the crop? :)

      • Classic

        DN (Digital Neo) - the lens is designed for mirrorless cameras with a crop sensor

        • Classic

          Any more questions?

          • Victor

            There will be no questions, there will be answers. The key word here is mirrorless, and this lens basically does not have the abbreviation "DC".

            Below is an explanation (with a small addition - at the very end, instead of “DC”, read “DN”:
            “And I also got a question: why do Sigma 16 / 1.4, 30 / 1.4, 56 / 1.4 lenses have DC DN in their name (DC for crop, DN for mirrorless), while Sigma 19 / 2.8 lenses , 30 / 2.8, 60 / 2.8 have only the DC mark in their name. "

              19 / 2.8 is kind of just DN, not just DC.

                The note with “below is an explanation ...” is about this :) Further, there was a quote from the text of Arkady.

    Arkady, hello! I have this lens, and here's the problem - with the new Olympus EM5-M III in continuous focus mode, the device hangs after a couple of refocusings. It can be solved only by overloading. But with the old EM10-MII everything is ok. Apparently due to the presence of phase sensors in the new Olympus. The situation is the same with the Sigma 60 2,8 lens. Nowhere on the Internet about this. Suddenly someone will come in handy.

    • Arkady Shapoval

      Thanks for the useful information! Therefore, I constantly point out:

      Important: the lens is from a third-party manufacturer, which imposes some restrictions on its practical use

    • Sergei

      Try updating your lens firmware. This is done in the same way as with native glasses. I have already sold this lens, so I cannot test its performance in this mode on a new camera. But I have two sigma contemporary 30mm and 16mm f1.4, with them and hybrid AF everything is OK.

  • Sergei

    Owned such a sigma under Micro 4/3. At one time I shot pretty tightly on it. I bought it because it was very cheap and small, at the stop and 1/3 lighter than the whale zoom at the same focal point. Has distortion even on mic. In all other respects, a rather nice lens, EGF 38mm is a sort of Change 8M with a covered hole.
    I was also always annoyed by the appearance of this lens. It also loves to pick up dust and sand between the body and the electronic focus ring and crunch when rotated.
    Sold it after buying Sigma 16mm f1.4. I also compared it head-on with the whale 12-50mm f3.5-6.3 - apart from the difference in aperture ratio, the differences are not particularly striking. By the way, the last lens turned out to be the most underestimated for me. It has protection against dust and moisture, internal focusing and zooming (mechanical and electronic) and a built-in macro mode 1: 2 at focal length 43mm, although the lens is rather large. It has less distortion at the wide end than the 12-40 2.8 pro. So it goes.

      Why covered? Smena like f / 4 had

      • Victor

        F4 on a full frame is roughly the same as F2 on a double cropped. Your cap.

      • Sergei

        Well, yes, I meant depth of field and viewing angle. In fact, given that the angle is calculated diagonally and the micra has an aspect ratio of 4: 3 versus 3: 2, when choosing an aspect ratio of 3: 2 on the mic, a little more crop and EGF in the region of 39mm are obtained, and according to the depth of field, the FF is hole 5.6. In general, the viewing angle is quite pleasant, maybe this focal point was used for a reason in many old cameras like the Smen or Olympus Trip 35, from which I unscrewed the lens. : D

        Sonya will have an EGF of 28.5mm and such lenses are also quite common for FF.

        • Michael

          Clear. Yes, mikra is unusual at first)
