In the review, I will call the Sigma 14mm 1: 1.8 DG A lens for short - Sigma 14 / 1.8 Art.

This review shows the lens version for Sony cameras with mount Sony FE (Full Frame) and Sony E (APS-C). Sigma 14 / 1.8 Art also available for Canon EF / EFS-mount DSLRs, Nikon F-mounts, Sigma SA-mounts and Leica L-mount mirrorless cameras (cameras from alliance Leica, Sigma, Panasonic).

It's important: Sigma 14 / 1.8 Art versions for Canon EF / Nikon F / Sigma SA mirrorless mounts and Sony E / Leica L mirrorless mounts (Sigma L + Panasonic L) differ significantly in their size and appearance.

It's important: The Canon EF version additionally supports the attachment of small filters on the mount side.

Sigma has a whole brood of high-aperture solutions with f / 1.4: 20, 24, 28, 35, 40, 50, 85, 105 mm. You can choose the right focal length for almost any task. There are two more unique lenses in the Sigma ART family of fixes, but with a slightly lower aperture: 14 / 1.8 (from this review) and 135/1.8.

Sigma 14mm 1: 1.8 DG A (ART)

Sigma 14mm 1: 1.8 DG A (ART)

Assembly

Assembled only in Japan. The lens is pleasant and weighty to the touch, weighing almost 1200 grams. The Sigma 14 / 1.8 Art has a highly convex front lens, which is protected by a built-in hood. Unfortunately, the lens does not support classic light filters.

The optical design of the Sigma 14 / 1.8 Art was originally designed for SLR cameras with a long flange distance. The Sigma 14 / 1.8 Art versions with Sony E and Leica L mounts are significantly longer than their versions for Nikon F, Canon EF, Sigma SA mounts. For the dimensions of the Sigma ART series lenses, I have prepared small video on your Youtube channel.

The focusing ring is rubberized, very wide, the base of the focusing ring is metal. The lens barrel is made of a composite material - TSC - Thermally Stable Composite (Thermally Stable Composite), which is less sensitive to temperature changes than conventional polycarbonate. Such a composite avoids deformation of the case with a large change in ambient temperature. This material is used by Sigma to build its' A | ART ',' C | Contemporary 'and' S | Sport '. In addition, the lens has metal bayonet mount.

The lens barrel is divided into matte and glossy parts that alternate. Glossy parts of the case get dirty easily.

There is a bayonet mount mark on the case.

The diaphragm consists of 9 blades; at all aperture values, a fairly round aperture is obtained.

Overall build quality is at a very high level.

It is stated that Sigma 14 / 1.8 Art is a protected lens... But the Sony E version of the Sigma 14 / 1.8 Art does not have a rubber seal on the mount side, and I also did not find any information about other seals to protect the lens from bad weather.

Sigma 14 / 1.8 Art supports working with usb dock, and also theoretically supports replacing one mount with another (done exclusively at Sigma service centers).

Sigma 14mm 1: 1.8 DG A (ART)

Focusing

To focus, the lens uses a special ultrasonic focusing motor 'HSM' (Hyper Sonic Motor) ring type... It is stated that a special, specially optimized HSM motor was used for the Sigma 14 / 1.8 Art.

The motor performs its work quietly during autofocus. The autofocus speed is fast (not lightning fast, but not closer to average, just fast). The focusing speed is sufficient for comfortable work in most photographic tasks.

With a camera sony a7 III 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 slowly and uncertainly due to the contrast-only focusing method.

You can fine-tune the focus using dock stations and utilities SIGMA Optimization Pro (there is support for the Russian language). In large cities, you can rent this station.

The focus ring is rubberized and rotates approximately 135 degrees in manual focus mode. When the extreme positions are reached, the ring does not abut, but continues to rotate freely. Manual aiming is convenient, but rubs a little. In auto focus mode, the focus ring does not rotate and you can hold the lens by it.

Lens has internal focus, the front and rear lenses remain stationary during focusing.

The lens has a window with a focusing distance scale in meters and feet. The number of values ​​on the scale is small, the scale itself is not very useful. There are only values ​​for 0.27, 0.35, 0.5, 1 meter and infinity mark. There is a depth of field scale for F / 4, 8, 11, 16.

The minimum focusing distance is 27 cm and the maximum zoom ratio is 1: 9.8, which is the norm for such lenses.

There is a lens housing focus mode switch 'AF | MF Focus' (auto focus / manual focus). Lens supports continuous manual focus control (Full-Time Manual Focus). Auto focus is disabled when you start rotating the focus ring manually.

Focus Features:

  1. Important: The quality of focusing work of the Sigma 14 / 1.8 Art strongly depends on the camera used and on the lens firmware, as well as on the system used for which the lens is made. For example, on the camera Sony a3500 focusing speed and tenacity are at an absolutely unsatisfactory level... At the same time on sony a7 III the lens behaves very well.
  2. The Sigma 14 / 1.8 Art has a moderate 'Focus Breathing' effect (changing the angle of view while focusing). When focusing towards the MDF, the angle of view decreases.
  3. Focus Shift (focus shift, changing focus distance due to iris)
  4. Sigma 14 / 1.8 Art does not have a hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens to infinity under any external temperature conditions. For accurate aiming at infinity, you can’t just bring the focus ring to its extreme position
  5. Important: The Sigma 14 / 1.8 Art is a third party lens. It may happen that it will not work correctly with some cameras.
  6. Sigma 14 / 1.8 Art supports docking station, with which you can update the lens firmware, as well as adjust / fix the focus

Image quality

The Sigma 14 / 1.8 Art generally has high optical performance. There is a slight drop in sharpness in the corners of the frame at F / 1.8. For super-wideness, the edges and corners of the frame are very important, since most often such lenses are used for scenes where good sharpness is needed throughout the frame. By closing the aperture, you can significantly improve the situation for the corners and edges of the image. The best sharpness across the entire frame is around F / 8.0. But I want to note that even the angles at F / 1.8 pleasantly surprised me, since I did not expect that such an ultra-wide width would be able to show such image quality. The center of the image at F / 1.8 is already good without any caveats.

There is a mild coma that diminishes significantly with f / 2.8-4 aperture. There is also moderate distortion and vignetting, chromatic aberration well fixed. The lens behaves well in backlighting.

The Sigma 14 / 1.8 Art has a lens profile in popular RAW converters, which makes it easy to automatically correct some distortions.

The Sigma 14 / 1.8 Art was released at the end of 2017, when 24 MP APS-C cameras and 50 MP Full Frame cameras were already on sale, and therefore, most likely, the lens was immediately designed to work on sensors with a high pixel density. 20 megapixels on a cropped camera (shot on Sony a3500) for Sigma 14 / 1.8 Art even at F / 1.8 it is not a problem.

My experience

I liked the lens very much. Good super-widths are something very nice and functional. But choosing a super-width is a very difficult task.

Good manual alternatives for the Sigma 14 / 1.8 Art can be Laowa 15 / 2, Samyang 14 / 2.4 XP, Irix 15 / 2.4 and Zeiss Milvus 15 / 2.8. True, no other similar full-frame 14mm focal length lens compares to the Sigma 14 / 1.8 Art in terms of aperture.

I repeat - Sigma 14 / 1.8 Art is an optically very good object.

  9. the lens belongs to the Sigma Art line with very high image quality and build criteria
  10. at the end of 2020, Sigma 14 / 1.8 Art has a record aperture F / 1.8 among all other similar photographic lenses. UPDATE: only in the spring of 2021 (4 years later) a similar lens from another manufacturer appeared - Sony FE 1.8 / 14 G GM

10 main disadvantages:

  1. the optical scheme has not been redesigned for mirrorless cameras (the optical scheme and the focal length are used from the mirror version, which increases the already considerable overall length of the lens)
  2. large weight (almost 1200 grams for the Sigma 14 / 1.8 Art versus 500 grams for LAOWA 15/2)
  3. there is no possibility to use classic front light filters (for example, LAOWA 15/2 72 mm filters can be used)

  5. no built-in image stabilizer (for example, it has Tamron 15-30 / 2.8 VC)
  6. there is no clear confirmation of the all-weather resistance of the lens (for example, there is no rubber mount for the mount)
  7. the glossy part of the case gets dirty easily
  8. small filters on the bayonet side can only be used in the Sigma 14 / 1.8 Art version for Canon EF
  9. high price tag at $ 1600 (end of 2020, for example, Sigma 20 / 1.4 Art costs about 900 dollars)
  10. small optical flaws, such as a slight drop in sharpness in the corners of the frame at F / 1.8, etc.

  • Alex

    > Ability to work with USB DOCK-station

    this is not a plus, but a minus.
    the lens should have accurate autofocus and good firmware right out of the box.

    • Arkady Shapoval

      even native lenses with a particular camera can give errors, while you need to take them to the SC, you can immediately correct the situation at home on your knee and adjust the lens for yourself

    • Victor

      Share this with the owners of your own lenses, including those with red and gold stripes.

      When it is possible to carry out self-adjustment at home, this is definitely a plus. However, no one forbids not to use the dock and act as with your family - take it to the SC.

    • Alexey

      This will significantly increase its price.

    • Vadim

      If the cameras (and the carcasses are also adjusted in different ways) and the lenses are perfect at the factory, then the price can jump a lot. And then the person came home, in most cases introduced an amendment to the camera and that's it. And the firmware is all the more necessary, especially for Nikon-Canon, with closed bayonets. It's strange that Sigma won't give up on a docking station instead of a tiny usb.

    Hello, Arkady! Thanks for your review. It was interesting to read, although I don't have that much money for a lens.

  • UstasFritZZZ

    Thanks for the interesting review. I never liked shiriki, but the examples of the photos were inspired.

  • Anton

    This lens looked at me for astrophoto, in fact, there are no analogues.
