Since more than one person has asked me for this type of information, I decided to create this page, which also may help give a feel for automatic SLR cameras in general to a person thinking of buying their first camera. These instructions are for the original Canon Rebel.
Features do change over camera generations.
As such other Canon Rebel models may operate somewhat differently. While I consulted the manual for my camera, these instructions are my own. Front of Camera Starting with the front of the camera, you'll see the lens release button on the right hand side, looking at it head on. Push this button to release the current lens, while turning it counter clockwise. The lens mounts and releases with the red dot on the lens being vertical.
