Sigma 50mm F/1.4 ART announced

Sigma has announced a new lens: 50mm F/1.4 ART, a fast “normal” prime lens for full-frame cameras. Last year’s 35mm F/1.4 ART is a huge success, and if this new 50mm is built on the same quality level, Sigma might have another best seller. This lens might be especially interesting for Canon users since all current Canon 50mm lenses have some drawbacks (50mm F/1.8 has a cheap plastic build quality, 50 F/1.4 is more than 20 years old optical design and 50L F/1.2 is way too expensive for most people).

The new Sigma 50mm ART is a completely new lens, not just a reworked 50mm F/1.4 EX DG HSM. The optical design is rather complicated for a 50mm lens since it has 13 elements in 8 groups. The lens has an ultrasonic-type focusing motor (should be quiet) and Sigma claims it has advanced AF algorithms. It is also compatible with Sigma USB dock (for firmware update and AF adjustments). Sigma promises exceptional optical quality and if it performs like the 35mm ART, we probably won’t be disappointed.
