Sigma 50mm F1.4 DG HSM | A
The 50mm F1.4 DG HSM is a premium 'normal' prime designed for full frame SLRs, and part of Sigma's 'Art' line. Not to be confused with the older 50mm D1.4 EX DG HSM, it's a completely new lens with a complex optical formula of 13 elements in 8 groups, and a minimum focus distance of 40cm. As part of the 'Global Vision' line it's also compatible with Sigma's USB dock and Mount Conversion Service. On APS-C / FX SLRs it acts like a 75mm short telephoto lens.

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.
Good for: Full frame users looking for the sharpest possible images, even when shooting at large apertures
Not so good for: Anyone who shoots a lot in damp or dusty conditions
