Bryan at The-Digital-Picture has completed his review of the Sigma 50mm f/1.4 DG HSM Art series lens. As you're probably used to reading, this lens is a stellar performer and nearly as good optically as the Zeiss 55 f/1.4 Otus, which costs 4 times as much.
“While I will dock a few points from this lens for occasional AF inconsistency, the Sigma 50mm f/1.4 DG HSM Art Lens is now the overwhelming favorite in the 50mm field. This lens delivers excellent image quality, has a beautiful design and for what you get, a very attractive price. The Sigma 50mm f/1.4 DG HSM Art Lens is the easy 50mm choice for those with a moderate budget.”
