Ultra-wide lenses aren't everyday tools for most photographers, but for some disciplines they're indispensable. I tend to recommend zooms at this end of the coverage range, as they're more versatile tools, giving you the ability to capture a wider variety of subjects without changing lenses.

Ultra-wide field of view; Very bright aperture; Very sharp; Solid build; Dust and splash protection; Available for multiple camera systems

Some barrel distortion; Soft edges and corners at wide apertures; Dim corners; Doesn't support front filters

This is an in-depth review of the Sigma 14mm f/1.8 DG HSM Art lens that was announced in February of 2017 along with a few other Sigma Art-series lenses. At the time of its release, Sigma proudly presented the lens as "world's first and only full-frame f/1.8 ultra-wide-angle lens", which was without...

This lens offers something other super-wides do not - a fast aperture! This separates it from the other super-wide products. It offers minimal vignetting for such a wide and fast lens and minimal coma - great for astronomy. I had no flare issues while imaging throughout the August 2017 eclipse.

This is a great kit combination, mainly because it includes the USB doc, and the cleaning kit. The lens is suberb! I use super wide angle lenses mainly for astrophotography and I was worried about coma which is a serious problem with most lenses.

So Sigma went where no man has gone before ... again. This time we'll explore the new Sigma 14mm f/1.8 DG HSM ART. Typically such ultra-wide lenses peak at a speed of (warp ... ah no ...) f/2/8.

The Sigma 14mm f/1.8 DG HSM Art lens stole the headlines as the first ultra-wide angle lens for full-frame cameras to break the f/2 barrier. No other ultra-wide angle rectilinear lens is as fast. Fast ultra-wide angle lenses are a rarity and your choices in this category are few.

Sigma's Art line-up has fast become one of the most highly regarded lens ranges on the planet. That's why we're excited to see the world's first 14mm f/1.8 prime, with an ultra wide-angle and fast aperture which could make it every astrophotographer's dream.

A very capable lens giving very pleasing results. It does however take some time to master but in a good way as I think after practice will be a favourite in my bag. Central frame is extremely sharp and perfect for stars and night scenes. Edge focus washes out quickly but also crops out easily.

Consistent Output; Durable; Quick Focus; Rugged; Sharp Focus; Strong Construction

Needs a little practice to find the sweet spot

Sigma has been breaking ground with many lenses in their Art series and the review-time-latest groundbreaker is this one, the Sigma 14mm f/1.8 Art Lens. The big deal this time While there are numerous lenses covering the 14mm focal length available, no full frame lens wider than 20mm ( another Art...

First of all you get a unique lens, unavailable in any other line-up. With that angle of view the best rivals offer you devices by about 1 EV slower. Secondly, the resolution results in the frame centre would break records even several years ago and they are typical for many Art series primes.

Solid and weather-sealed casing,, Sensational image quality in the frame centre already from the maximum relative aperture,, Good image quality on the edge of the APS-C,, Lack of problems with longitudinal chromatic aberration,, Imperceptible lateral chromatic aberration,, Sensible distortion...

Resolution on the edge of full frame could have been a bit better,, Weak performance against bright light,, A bit too high coma level,, Impossible to use classic filters.
