Frequently asked questions

What is the equivalent focal length of the EF-S 24mm f/2.8 STM?

About 38mm on a Canon APS-C camera, a slightly wide normal view. This comes from the 1.6x crop factor of Canon APS-C sensors.

Can the Canon EF-S 24mm f/2.8 STM be used on a full-frame camera?

Not on full-frame DSLRs. EF-S lenses are made for APS-C and the rear element would hit the mirror. On a full-frame EOS R body with the EF-RF adapter it works, but the camera crops the image to APS-C size.

EF-S 24mm f/2.8 STM vs EF 40mm f/2.8 STM?

The EF-S 24 frames like a 38mm lens on APS-C, a wide-normal view. The EF 40mm gives a tighter 64mm-equivalent view and also works on full-frame bodies.
