Canon's expansive line of digital SLR cameras is designed to be customizable, allowing photographers to experiment and be creative while taking advantage of the wide range of photographic options. Canon SLR lenses are central to these creative options.
EF and EF-S Lens Mount
Canon digital SLR cameras released prior to 2003 have an EF mount for Canon's line of lenses. In 2003, some Canon EOS models were released with an EF-S mount. This was Canon's way of entering the "prosumer" market, designing affordable professional SLR cameras with smaller censors and therefore shorter lenses (in terms of the space between the rear focus and mirror).
Compatibility
All Canon cameras with an EF-S mount can support both EF and EF-S lenses. To know if your camera is EF-S compatible, look for a red dot on the lens mount; EF cameras have white dots. Note that cameras with an EF mount are not compatible with EF-S lenses.
Third-Party Lenses
Third-party lens manufacturers like Sigma and Tamron makes lenses for most major DSLR camera bodies and are aware of all of the distinctions between lens types and lens mounts. When buying a third-party lens, make sure to verify the mount type to ensure compatibility.
