The Sigma 14-24mm f2.Eight Artwork is an ultra-wide angle zoom lens with a continuing f2.Eight focal ratio that’s designed for full-frame cameras and accessible in Canon, Nikon and Sigma mounts. It will also be used with Sony E-Mount our bodies utilizing Sigma’s MC-11 mount converter.
Introduced in February 2018 it enhances Sigma’s earlier 12-24mm f4.Zero Artwork lens from 2016 and goes straight up towards different ultra-wide zooms, most notably Nikon’s AF-S 14-24mm f2.8, Canon’s EF 11-24mm f4, and Tamron’s 15-30mm f2.Eight VC fashions. As you’ll anticipate from any new Sigma Artwork lens it’s suitable with their USB-dock to effective tune numerous traits of the AF, plus in case you change our bodies, you possibly can pay to have the mount swapped to your new system. The inclusion of this lens in Sigma’s “Artwork” line signifies a top-notch optical design with a declare of minimal distortion at 1% or much less which additionally brings with it a list-price of 1300 USD / 1450 EUR.
To learn the way the brand new Sigma 14-24mm f2.Eight Artwork performs I examined it towards Tamron’s 15-30mm f2.Eight VC on the demanding D850 physique. So in case you’re looking for a big aperture full-frame ultra-wide zoom, you’ve come to the appropriate place!
Details from the catalog
As normal I’ll take a look on the technical knowledge of the brand new Sigma first. I’ve rated the options with a [+] (or [++]), when it’s higher than common and even cutting-edge, a  if it’s commonplace or simply common, and [-] if there’s an obstacle. For comparability I take advantage of the Tamron 15-30mm f2.Eight VC (“Tamron” for brief) and the Sigma 12-24mm f4.Zero Artwork (“Sigma 12-24”).
Dimension (diameter x size): 96 x 132mm (3.Eight x 5.2in.) together with the built-in lens hood. Zooming doesn’t change the full size of the lens though the entrance lens-group strikes out when zooming to 14mm focal size (see following picture). The Tamron is 98 x 143mm, the Sigma 12-24 is 102 x 130mm. So all lenses on this league are fairly cumbersome. 
Weight: 1122g (39.6 oz.). The Tamron is 1052g and the Sigma 12-24 weighs 1130g. 
Optics: 17 parts (together with 6 particular dispersion and three aspherical parts) in 11 teams vs. 18/13 for the Tamron and 16/11 for the Sigma 12-24. Sigma employs fluorine coating on the entrance of its new lens to repel water, mud, and grime and will make for simpler cleansing. [+]
Closest focus distance is 0.26m (10.2 in.) with a magnification of 1:5.Four at 24mm focal size. In my take a look at I used to be in a position to get all the way down to 1:4.Eight at 0.24m with handbook focus identical to with the Sigma 12-24. The magnification of the brand new Sigma is kind of good however you could have solely 6cm (2.5 in.) of working distance at minimal focus distance. A magnification of 1:10 is achieved at 0.36m giving a working distance of 0.18m. The Tamron achieves a most of 1:4.Four magnification at 0.28m distance and 30mm focal size in handbook focus. 
Filter-thread: Not one of the ultra-wide angle zooms from Sigma, Tamron, Nikon or Canon supply a filter-thread. Their bulbous entrance parts forestall that. So you have to get some non-standard mounting system and a brand new set of filters. There could be an opportunity to suit Sigma’s rear filter holder RFH-11 for the Sigma 14mm f1.Eight Artwork to the lens – however that appears to be for the Canon model solely. Higher strive/ask before you purchase! [-]
Picture stabilization: No. The one ultra-wide angle zoom that provides optical picture stabilization is the Tamron. 
Auto focus: HSM (Hyper Sonic Motor), so it additionally works on digital camera our bodies which don’t have an AF-drive in-built like Nikon’s D3x00/5×00. Guide-focus override is by merely turning the main target ring. Similar with the competitors. However the brand new Sigma permits you to alter focus fine-tuning at 4 focal lengths and 4 distances with the USB-dock. [+]
Covers full body/FX or smaller = superb. Similar with the competitors. [+]
Value: round 1450 EUR (incl. 19% VAT) / 1300 USD. The Tamron goes for 950 EUR / 1100 USD and the Sigma 12-24 for round 1450 EUR / 1600 USD. 
Comes with a pleasant semi comfortable lens-case plus strap. Like most ultra-wide lenses, the Sigma 14-24mm f2.Eight ART has a built-in petal hood, however uniquely it may be transformed by Sigma to a shorter rounded design to forestall or reduce points with shadows or different lenses in multi-camera VR environments. The lens hood can’t be eliminated by the person which is much less sensible for cleansing the bulbous entrance component. One other slight drawback is that the entrance lens-cap doesn’t securely arrest in place when mounted: it might match tighter than related hoods from Nikon or Tamron however can nonetheless work itself off when it rubs towards your garments. Samyang has proven with the 12mm f2.Eight fisheye that you just nonetheless can constructed a correct locking mechanism for the sort of lens-cap. Samyang additionally has a removable lens hood which makes it far simpler to scrub the outer elements of the entrance component. So that is one thing the opposite producers ought to take into consideration. 
Distance data is relayed to the digital camera, so the digital camera and flashes can do all of the superior exposure-related stuff with this lens. Similar for the competitors. The Canon model of the lens can also be suitable with the lens aberration corrections accessible in latest our bodies to compensate for vignetting, chromatic aberrations and distortion. [+]
Sigma’s service can change the mount of the lens between Nikon, Canon or Sigma (at a value). Plus you too can purchase Sigma’s MC-11 Mount Converter for 250 EUR/USD to place the lens on a Sony E-Mount physique (solely accessible for adaptation of Sigma lenses with Sigma or Canon mount, not Nikon mount). These are distinctive characteristic that no different producer provides. [++]
Aperture ring: no, identical as with the competitors. The aperture is actuated electromagnetically within the Nikon-version too which makes it the equal of a contemporary E-type Nikon lens and places away with the mechanical coupling that Nikon makes use of on all older lenses. 
Sealing: sure, a rubber grommet on the lens-mount plus additional particular weather-sealing all through the development. [+]
The rating within the “features-department” is 1[-]/7/7[+]. So the lens is well-featured with the distinctive choice to get the lens-mount swapped or use an adapter for Sony’s E-Mount which no different producer provides. The one actual draw back is the necessity for particular filters.
- Nikon has the 14-24mm f2.8G ED. It bought a Extremely Advisable in 2013 and prices round 1900 USD / 1800 EUR. See my Nikon 14-24mm f2.8G assessment.
- From Sigma there’s their 12-24mm f4.Zero Artwork for round 1600 USD / 1450 EUR. This zoom has a 2mm shorter focal size producing an angle of view of 122 levels but it surely has a focal ratio of solely f4.Zero giving up one cease of sunshine gathering energy. It got here Extremely Advisable in my Sigma 12-24mm f4.Zero Artwork assessment.
- Canon has the Canon EF 11-24mm f4.Zero L USM from 2015 which is the World’s widest rectilinear full-frame zoom with a road value round 2700 USD / 2900 EUR. It earned a Extremely Advisable in Gordon’s Canon EF 11-24mm f4L USM assessment.
- Tamron provides the one stabilized zoom on this group which additionally seems to be the most affordable: the Tamron 15-30mm f2.Eight Di VC USD for about 1100 USD / 950 EUR. Its widest angle of view is “solely” 110 levels but it surely provides 6mm on the lengthy finish of its zoom vary giving it 25% extra attain in comparison with the opposite zooms. It earned a Extremely Advisable in my Tamron 15-30mm f2.Eight VC assessment.
- Sony has the FE 12-24mm f4G for E-mount digital camera which exploits the brief flange to sensor distance for a compact and light-weight design. Gordon’s tried it and put collectively some pattern pictures in his Sony FE 12-24mm assessment to this point.
Right here is the angle of view that the brand new Sigma 14-24mm covers with its 1.7x zoom:
Following is the protection of the Tamron 15-30mm zoom. That is what the lacking 1mm on the brief finish and the extra 6mm on the lengthy finish appear like:
Focus and zoom
Focus accuracy and repeatability is vital to constantly produce sharp pictures. Repeatability (the accuracy of deal with the identical topic after repeated focus-acquisition in section detect mode) of this lens at commonplace settings and 24mm focal size is fairly good (measured 97.8% in Reikan FoCal) with no actual outliers over a sequence of 40 pictures. There’s a larger focus variation when the lens focuses from a more in-depth distance in the direction of a extra distant goal. This led to some pictures being not optimally targeted. At 24mm focal size the lens focuses with out looking in round 0.35sec from infinity to 0.36m, which could be very quick, sooner than the Sigma 12-24. The Tamron is of comparable pace, has a greater repeatability of 99.5%, and in addition produced no outliers in 40 pictures underneath the identical take a look at situations.
The main target ring has no slack/play between its motion and the focus-action and a throw of 110 levels. Its rubberized floor is 22mm extensive. The zoom ring turns by 80 levels and has a 12mm extensive rubber floor which is fairly slim particularly contemplating its stiffness. The main target rings turns simpler and will be operated with one finger. Each rings flip in the identical route as Canon customers are used to however that is the entire reverse of what Nikon does. The main target ring is on the entrance and the zoom ring nearer to the digital camera. I might have preferred the zoom ring to be additional away from the physique as it’s fairly near the protruding nostril the place some digital camera our bodies have their built-in flash. Personally I desire having the zoom ring on the entrance which is what the Tamron provides.
AF-operation is barely audible from the surface, and in case you file video with the built-in microphone the AF-drive produces virtually no noise whereas shifting with solely comfortable clicks firstly or cease of focus-movements.
As you pull focus, you’ll discover some focus respiration: the picture turns into much less magnified at nearer focusing distances. When I adjusted the main target from infinity to 0.36m on the Sigma at 24mm focal size, I measured a 3% lower in magnification. The Tamron 15-30mm f2.Eight VC reveals the same impact. So each lenses shouldn’t produce disturbing focus respiration when recording video. Superb!
