Mike is correct. All of the newer autofocus lenses for Canon are EF. FD is the old breech-lock design that fits older manul cameras up to the early 80's. If your camera is of EOS design FD lenses will only fit using a EF to FD converter. The lens would fit then but your on board meter will not work at all and I do not know what ramifications there will be to image quailty or amount of light leakage.
