The Canon RF 24-50mm f/4.5-6.3 IS STM and the Canon RF-S 18-45mm f/4.5-6.3 IS STM side by side, computed from this guide's catalogue.

Which to pick

Pick the Canon RF 24-50mm f/4.5-6.3 IS STM if you want a wider view (from 24mm equivalent) and coverage of full frame, so it suits the larger-sensor bodies too. Pick the Canon RF-S 18-45mm f/4.5-6.3 IS STM if you want more reach (to 68mm equivalent); a design for APS-C, which usually means smaller and lighter; and a lighter lens (130 g against 210 g).
