The Canon RF 15-30mm f/4.5-6.3 IS STM and the Laowa 8-16mm f/3.5-5 Zoom CF side by side, computed from this guide's catalogue.

Which to pick

Pick the Canon RF 15-30mm f/4.5-6.3 IS STM if you want optical stabilisation, which helps most on bodies without it; autofocus; more reach (to 30mm equivalent); coverage of full frame, so it suits the larger-sensor bodies too; and a lighter lens (390 g against 463 g). Pick the Laowa 8-16mm f/3.5-5 Zoom CF if you want a brighter f/3.5 (0.7 stops more light), for dim light and softer backgrounds; a wider view (from 12mm equivalent); a design for APS-C, which usually means smaller and lighter; and a fit on more cameras (106 against 18 in this guide).
