7Artisans AF 27mm f/2.8 vs Sony FE 40mm f/2.5 G

The 7Artisans AF 27mm f/2.8 and the Sony FE 40mm f/2.5 G side by side, computed from this guide's catalogue.

Which to pick

Pick the 7Artisans AF 27mm f/2.8 if you want a design for APS-C, which usually means smaller and lighter and a fit on more cameras (88 against 41 in this guide). Pick the Sony FE 40mm f/2.5 G if you want a brighter f/2.5 (0.3 stops more light), for dim light and softer backgrounds and coverage of full frame, so it suits the larger-sensor bodies too.
