At the beginning of 2018, Sigma announced the release of a full-frame wide-angle zoom lens with an extremely low level of aberration. In the manufacturer’s terminology: “almost zero distortion”, and more specifically: the distortion level is less than 1%, and “minimal transverse chromatic aberration, glare and ghosting”. In simple terms, the lens almost does not distort the geometry of the image during wide-angle shooting, unlike “class” lenses with close viewing angles.

So, get acquainted – Sigma 14-24mm f / 2.8 DG HSM Art.

Design, ergonomics, management

The first thing you pay attention to when taking the lens in your hands is its weight: 1.2 kg. If you add a camera and additional accessories, the total weight of the kit may exceed 3 kg. It turns out that this is a lens for serious work. Obviously not for idle walks around the city.

The lens gives the impression of a quality and reliable product. The ribbed surfaces of both rings prevent the hands from slipping during operation.

The zoom ring travels a little less than a quarter of a revolution and is moderately tight and smooth – setting the desired focal length is easy. The focus ring rotates with the same effort, and its travel from lock to lock also amounts to a little more than a quarter of a revolution. This is quite enough not to intercept the ring when focusing in manual mode and precisely control the shooting object in the field of sharpness.

The metal mount allows you to not be afraid of damage to the connection when changing lenses. All communication with the camera is carried out electrically – through a group of contacts. The lens is available in Canon EF and Nikon F mounts.

When zooming, the external dimensions of the lens do not change. Although a slight extension of the front lens occurs when adjusting the focal length, it does not go beyond the dimensions of the lens hood.

The hood is not removable, but this does not interfere with the storage and transportation of the lens, thanks to a special cover that is put on the hood without latches and does not slip during vertical transportation thanks to a velvet lining on the inside.

Perhaps with regular use, this pad will be erased. However, during the test, the lid did not slip and held tight.

The hood is petal, but in the company service center it can be replaced with the original round one. This will be appreciated by videographers who shoot material to create virtual reality.

Due to the large radius of the front lens sphere, filters can only be used on this lens with an external mounting system.

Sigma made sure that bad weather does not become an obstacle to work: the Sigma 14-24mm f / 2.8 DG HSM Art lens has dust and moisture protection. It is well balanced and, despite its large weight and dimensions, it is comfortable to work with it.

The angle of the field of view varies from 114.2 to 84.1 degrees. This allows you to get photos with the unusual transmission to the naked eye of the human space (perspective).

Lens in work

When you look into the viewfinder for the first time, the picture just takes your breath away: where does so much space and detail come from in one frame ?! A world very unusual for the human eye opens up to a photographer shooting on this lens, especially in a short-focus position.

Shooting at the minimum focal length.

Autofocus speed pleasantly surprised. I didn’t hope that his work would be so quick: I expected to see a slow, slow autofocus with a lot of mistakes and mistakes. In fact, the focus worked quickly, accurately and predictably! Another sign of a professional lens. In tandem with the camera’s tracking autofocus, the Sigma 14-24mm f / 2.8 DG HSM Art manages to catch even a fast-moving camera object.

Sigma 14-24mm f / 2.8 DG HSM Art is not equipped with a stabilization system. But, thanks to its rather considerable weight, which is added to the weight of the camera, the system has sufficient inertness. This made it possible to shoot handheld at shutter speeds of the order of 1 / 20-1 / 25 seconds with a camera with a sensor resolution of 20 megapixels.

Image quality

The main characteristic of the lens is image quality. In the Sigma 14-24mm f / 2.8 DG HSM Art model, distortion is almost completely corrected, which is especially valuable in architectural and interior photography.

In the photographs there is practically no “barrel” or “pillow” that is inherent in many other wide-angle lenses. However, in other genres, the absence of geometric distortions will be a plus.

The lens design uses an optical scheme with 17 elements in 11 groups, which includes three aspherical lenses and six low-dispersion glass lenses created by precision molding of glass under pressure: three SLD lenses and three FLD lenses with fluorite-like optical properties.

Prospective distortions caused by tilting the camera, if necessary, are very easily compensated in a graphics editor or converter, however, due to a small loss of the coverage angle.

No correction.

Image sharpness, even at the open aperture of F2.8, is quite high across the entire field of the frame, but not yet maximum. Vignetting is clearly visible in the corners of the frame.

When you close the aperture to F4, the picture literally “rings”, but the darkening at the corners does not decrease.

Further, at aperture values ​​of F5.6 and F8, sharpness remains at a stable high level.

A slight decrease in sharpness begins only when the aperture is closed stronger than F11: no one canceled the diffraction phenomenon. At the same time, after F11, vignetting, which is noticeable on more open diaphragms, practically disappears.

At the long end of the zoom, the same picture with sharpness is observed. Photos are quite sharp already with the F2.8 aperture.

Similarly, after F11, sharpness decreases slightly. However, there is no vignetting starting with an open aperture.

Another feature of the lens was the fact that in the case of lateral illumination, for example, at night from lamps or lanterns or during the day from the sun, color flares of various shapes may appear on the photo.

This feature of the lens must be taken into account by everyone who will work with it, for example, in a city where a large number of different light sources fall into the frame.

A huge plus, in my opinion, is the use of a 9-blade aperture in the lens design. The effect of this is especially noticeable when shooting on covered diaphragms at night. Around the point light sources appear beautiful diverging rays, as from the use of a star filter. In total there are 18 of them – this is the doubled number of aperture blades.

When shooting against the sun, the image contrast practically does not fall, the lens holds backlight very well, allowing you to get a good result without using HDR processing.

Chromatic aberration in the images is difficult to find, as stated by the manufacturer. But if color ghosting still appears, then the camera will help to remove them: the lens is compatible with Canon’s chromatic aberration and diffraction correction function.

The Sigma 14-24mm f / 2.8 DG HSM Art lens has a f / 2.8 aperture over the entire focal length range. With a minimum focusing distance of 26 cm and a maximum scale of 1: 5.4, this zoom is unlikely to be used for macro photography. However, close-ups of small objects are convenient for them to shoot. The background is blurred very softly, without ghosting and contrasting spots.
