Photographer Christopher Frost recently published an interesting review of the new Sigma 20mm f/1.4 Art lens which seems to be an excellent performer.
For years the widest, fastest lens for full frame cameras was the Sigma 20mm f/1.8, which is an interesting lens but has less than stellar performance. The new lens on the other hand which was announced just two months ago seems to be yet another exceptional ART lens from Sigma with great sharpness across the picture even wide open (from around f/2 the IQ seems to be really impressive even in the corners), relatively low barrel distortion, fast AF and great build quality.
Frost tested the lens on both the Canon 6D and the Canon 60D (a shame he didn’t have a D810 or 5D S to really see the resolving power of this lens).
