Digital Camera World Verdict

The Canon RF-S 18-45mm f/4.5-6.3 IS STM is an incredibly lean, lightweight lens that's a great match for the EOS R7 or R10. Its image quality is better than it has any right to be, and it even boasts 4 stops of image stabilization (which ramps all the way up to 6.5 on a body with IBIS), and it's an ideal everyday companion for stills and video shooting.

The Canon RF-S 18-45mm f/4.5-6.3 IS STM is born of necessity. The release of two new APS-C Canon cameras means the release of two new APS-C Canon kit lenses – but is this compact zoom worth picking up on its own merits?

While the Canon RF-S 18-45mm f/4.5-6.3 IS STM is designed to be used with the Canon EOS R10 and Canon EOS R7 (and, primarily, the former as it's much cheaper and lighter), it uses the same RF mount as full frame cameras like the Canon EOS RP and Canon EOS R6 – though these bodies will automatically switch to a cropped APS-C shooting mode.
