Sigma 14-24mm f/2.eight DG HSM | Artwork evaluation

There are a number of wide-angle high and zoom lenses in Sigma’s ‘Artwork’ line of World Imaginative and prescient optics. This newest addition is maximum very similar to the 12-24mm | Artwork lens, which itself is a revamp of the older 12-24mm II lens, gaining a relentless f/four aperture and a discount in distortion. The brand new 14-24mm is nearly the similar measurement and precisely the similar weight. It doesn’t cross relatively as extensive, with a most viewing attitude of 114 as a substitute of 122 levels, however is an f/prevent sooner and guarantees even higher symbol high quality.

Options

  • Extremely-high-precision moulded glass aspherical part
  • Ring-type ultrasonic AF machine
  • Compatibility with Sigma’s not obligatory USB Dock

The 14-24mm is to be had in Canon, Nikon, Sigma and Sony E-mount choices, each and every of which has the similar optical line-up, that includes various upper-class glass. Best of the checklist is an ultra-high-precision moulded glass aspherical part. Sigma claims that its production procedure for this kind of optical part allows a brand new usual in excellence for wide-angle lenses. There are 3 aspherical parts in overall, blended with 3 FLD (Fluorite-grade Low Dispersion) and 3 SLD (Particular Low Dispersion parts). The whole optical trail is in response to 17 parts organized in 11 teams.

Conventional of Sigma’s Artwork lenses, autofocus is courtesy of a ring-type ultrasonic machine, which is each very speedy and whisper-quiet, in addition to enabling full-time handbook override. The Canon-fit version of the lens allows in-camera corrections for aberrations like colour fringing, peripheral illumination and distortion, which we’ll come to later. There’s additionally compatibility with Sigma’s not obligatory USB Dock, for fine-tuning efficiency and making use of firmware updates, from a hooked up laptop.

Construct high quality and dealing with

  • Immaculately engineered
  • Complete set of weather-seals
  • Center of attention ring has a easy and fluid really feel

Encasing the top-notch glassware, the barrel and mounting plate are immaculately engineered with a complete set of weather-seals. Conventional of ultra-wide lenses, a integrated lens hood offers bodily coverage to the bulbous, sticking out entrance part in addition to serving to to cut back ghosting and flare. Whilst the full bodily dimensions stay fastened all through the zoom vary, the entrance part does lengthen and draw closer to the entrance fringe of the hood at shorter focal lengths. Sigma gives an after-sales carrier to take away the fastened hood, which will also be preferable if the use of the lens for multi-camera, digital truth videography.

The focal point ring has a easy and fluid really feel. As you’d be expecting on this calibre of lens, there’s a focal point distance scaled underneath a viewing panel. In opposition to the rear, the zoom ring has a in a similar fashion easy, high-precision really feel and rotates in the similar path as own-brand Canon lenses, for extending or lowering the focal duration.

Efficiency

  • Sharpness and distinction are very spectacular
  • Distortion extremely low for this category of lens
  • Direct daylight can strike the entrance part

As with different Sigma Artwork lenses that we’ve examined, sharpness and distinction are very spectacular, even if taking pictures wide-open at f/2.eight. For the sort of wide-angle lens, the brand new Sigma is especially very good at maintaining sharpness against the perimeters and corners of the body. 

Any other actual fulfillment is that chromatic aberrations are almost not possible to identify

In a similar way, ranges of distortion are extremely low for this category of lens. Certainly, distortion is just perceptible all through all of the zoom vary, even if taking pictures straight-sided constructions in architectural pictures. Any other actual fulfillment is that chromatic aberrations are almost not possible to identify, even round high-contrast edges against the extraordinary corners of the body. All in all, the compatibility with Canon’s in-camera corrections are rather educational.

At or close to the shortest focal duration, something you do wish to be cautious of is that direct daylight can strike the entrance part until you’re taking pictures with the solar just about at the back of you. It will create ghosting and flare and, for this side of efficiency, the Sigma is extra reasonable than remarkable, when compared with an identical ultra-wide zooms just like the competing Nikon 14-24mm.

Verdict

We’ve been inspired via all of Sigma’s wide-angle Artwork lenses, and the 12-24mm offers an astonishing most viewing attitude. This one doesn’t cross relatively as extensive however delivers even higher symbol high quality with excellent sharpness and distinction, restrained vignetting and extremely minimum fringing and distortion. For us, the 14-24mm f/2.eight is the pick out of the crop, and outperforms competing own-brand lenses from the likes of Canon, Nikon and Sony.
