The TTArtisan AF 14mm f/3.5 and the Zeiss Loxia 21mm f/2.8 side by side, computed from this guide's catalogue.

Which to pick

Pick the TTArtisan AF 14mm f/3.5 if you want autofocus; a design for APS-C, which usually means smaller and lighter; and a fit on more cameras (72 against 41 in this guide). Pick the Zeiss Loxia 21mm f/2.8 if you want a brighter f/2.8 (0.6 stops more light), for dim light and softer backgrounds and coverage of full frame, so it suits the larger-sensor bodies too.
