Canon RF 24-105mm f/4 L IS USM
The RF 24-105mm f/4 L IS USM is an enthusiast-tier (69) stabilized full-frame RF standard zoom with a 77mm thread at 700g. Its versatile range makes it the default RF do-everything L lens for general shooting. The constant f/4 aperture is the obvious limit, so anyone who needs f/2.8 for low light or shallower depth of field should step up.

Ecosystem
Compatibility
Built around Canon RF mount. Make sure the rest of your build uses the same platform before you buy — mismatched sockets, mounts or standards are the most common return reason. Check it in the builder →
Upgrade path
Buying today, the Sigma 15mm f/1.4 DC (APS-C, E/X/RF-S) scores higher for less — the smarter pick in lenses unless you specifically want this one. See it →
