Olympus M.Zuiko 12mm f/2 vs TTArtisan 17mm f/1.4

The Olympus M.Zuiko 12mm f/2 and the TTArtisan 17mm f/1.4 side by side, computed from this guide's catalogue.

Which to pick

Pick the Olympus M.Zuiko 12mm f/2 if you want autofocus and a design for Micro Four Thirds, which usually means smaller and lighter. Pick the TTArtisan 17mm f/1.4 if you want a brighter f/1.4 (1.0 stops more light), for dim light and softer backgrounds; coverage of APS-C, so it suits the larger-sensor bodies too; and a fit on more cameras (162 against 49 in this guide).
