Canon EF Lenses
Introduction
The Canon "Electro-Focus" (EF)
lens mount is the standard lens mount on Canon "Electro-Optical System"
(EOS) Digital and
Film
SLR cameras. It was originally designed for full frame, 35mm
cameras, but is fully compatible with the Canon
Digital SLR range.
Canon Digital SLR cameras have
APS-C sized image
sensors and Canon now produce a range of lenses with an
EF-S
lens mount, these lenses are designed to focus a smaller area of light
on the APS-C sensor and have extended length internal optical elements
designed to bring the lens elements closer to the sensor. This means
that EF lenses are compatible with cameras with EF-S lens mounts, but EF-S
lenses are not compatible with cameras designed with EF lens mounts as
the extended optics would foul the
reflex mirror. My Canon Lenses I have
