Sigma 50mm F1.4 DG HSM Art Review
The Sigma 50mm F1.4 DG HSM | Art is distinctly large, heavy and expensive for its type. However this is more than made up for by its fast silent autofocus, solid build quality, and absolutely outstanding optics. Overall it stakes a very serious claim to be the best autofocus 50mm prime on the market right now.
