Canon EF / EF-S
Full-frame and APS-C Canon EOS DSLR systems.
Canon EF lenses work on both the full-frame EF and the APS-C EF-S DSLRs listed here. Canon EF-S lenses cannot mount on full-frame EF DSLRs.
Canon APS-C bodies show about 1.6× the full-frame view. The EF-EOS R adapter opens a separate route to EOS R cameras.
