Top lens info: Sigma 50mm ART lens matches the best Zeiss Otus.

Sigma is one of the third-party lens companies making lenses for the Micro Four Thirds system. And I guess you already know about their most recent “ART” lens series. Well, let’s hope they will make some new ART lens for MFT lens too because their recently released 50mm f/1.4 ART lens for DSLR mounts shows a quite impressing quality! SLRgear tested the lens (read here) and the Sigma manages to almost match the $4,000 Zeiss Otus performance:

While the Zeiss does show better performance in the corners at ƒ/1.4 on a full-frame camera, the other optical performance characteristics are pretty evenly matched.

The Sigma sells for DSLR system only ($949 at BH). But I hope Sigma will make a more compact designed version for the MFT system!
