Sigma announces all-new 50mm F1.4 DG HSM 'Art' lens
CES 2014: Sigma has announced the 50mm F1.4 DG HSM | A, a fast 'normal' prime for full frame DSLRs. It will also work on APS-C / DX format cameras, offering a 75mm equivalent short telephoto effect. It's a completely new lens, rather than a revision of Sigma's existing 50mm F1.4, with an unusually complex optical formula for its type (13 elements in 8 groups). It'll come in Canon, Nikon, Sigma and Sony mounts; pricing and availability are still to be confirmed.
