Sigma 12-24mm f/4 ‘ART’ Lens Review
On this review photographer Christopher Frost looks at another ultra wide angle full frame lens – the new Sigma 12-24mm f/4.
We first saw the new Sigma 12-24mm f/4 at Photokina 2016 last year and it is a newer ART version of Sigma’s previous 12-24mm lens (for a long time the widest range zoom lens for FF). As it happens several new FF ultra wide lenses just came into the market and Canon also released it’s own ultra wide angle zoom lens – the Canon EF 11-24mm f/4 USM which Frost reviewed earlier this week.
The new sigma is ;large and heavy but has a very good build quality. The lens is is sharp but not as sharp as the Canon (at 12mm) but with less CA. Stopping down to f/5.6 or f/8 will improve the sharpness. At 24mm you will need to go to f/8 to really get a sharp image in the corners (f/5.6 is perfect in the center).
All in all the Sigma 12-24mm f/4 ART appears to give a much better value for money than the much more expensive Canon (although the Canon is a bit wider and a bit sharper wide open).
As for pricing this lens cost around $1600.
