Ef Ef S Lenses
Photographers: What are the EF and EF-S?

Canon lenses are made. EF job in digital cameras and film cameras … EF-S "only" work on the 30D and 20D Rebel Rebel XTi The Canon EF-S mount is a derivative of the EF lens mount created for a subset of the digital Canon single lens reflex cameras with APS-C size image sensors. The "S" in EF-S stands for "short back focus", which means that the element back of the lens is closer to the image sensor than regular 35 mm SLR camera. The biggest advantage is that it allows small and less expensive lenses wide angle.

Canon EF lens stays in one and not the other.?

I had a Canon Rebel XS for about 5 months and everything was wonderful. I have the kit that goes with (EFS 18-55mm), and additional lens (EF 75-300mm). I recently bought a Canon EOS-3 film and hopes EF EF lenses work on my ride. The fit 75-300mm on the EOS-3, but the 18-55mm does not. What could be the problem? Could it be that 18-55mm Sai?

Canon cameras can not use EF EF. 18-55mm lens is an EF which was designed specifically for use in sensor DSLR APS-C. You can use both EF and EF DSLR. The good news is that there really one or two EF lenses you need. The objective kit 18-55mm angle and wide EF 10-22mm. All focal lengths are available in other EF mount. Also for the majority of EF lenses are better than EF.
