The Canon RF 15-30mm f/4.5-6.3 IS STM and the Canon RF-S 14-30mm f/4-6.3 IS STM PZ 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 a wider view (from 15mm equivalent) and coverage of full frame, so it suits the larger-sensor bodies too. Pick the Canon RF-S 14-30mm f/4-6.3 IS STM PZ if you want a brighter f/4 (0.3 stops more light), for dim light and softer backgrounds; more reach (to 45mm equivalent); a design for APS-C, which usually means smaller and lighter; and a lighter lens (181 g against 390 g).
