The “S” in EF-S stands for “Short back focus”. Back focus is the distance from the rearmost point of the last optical surface of the lens to the film or sensor. There are certain advantages in lens design in having this distance small for wide-angle lenses, but the limit in SLR cameras is determined by the need the SLR mirror must not hit the lens when it flips up.

The mirror on the Digital Rebel is smaller than that of full frame 35mm cameras because the sensor is smaller and the mirror only needs to be large enough to cover the area of the sensor. This allows the use of a lens with a shorter back focus distance.
