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.
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.
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.
Main technical characteristics of Sigma 19mm 1: 2.8 DN A:

Other fixes from Sigma ART usually have a much larger aperture ratio than 1: 2.8.
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.
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).
- No lens barrel focus mode switch... Switching should be performed via the camera menu or camera controls.
- 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.
- 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.
- 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.
- Focus Shift (focus shift, changing focus distance due to iris)
- Important: The Sigma 19 / 2.8 Art is a third party lens. It may happen that it will not work correctly with some cameras.
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.
Sample photos on Sony a3500 (APS-C)
Camera used for examples Sony a3500 with EXMOR APS-C CMOS 20 MP sensor. All photos are on-camera JPEG. Sony a3500 cannot shoot exclusively in RAW format, but only in RAW + JPEG or JPEG. The EGF for Sony E cameras with APS-C sensor is about 28 mm.
RAW source files ('.ARW') can be download from this link (13 files, 200 MB).
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.
