Close, but EF-S lenses will not work on FF cameras for another reason. In the Canon system the EF-S stands for short back focus, meaning that the rear element is able to protrude further into the camera body that a 35mm lens. This is only allowed by decreasing the size of the reflex mirror.
well that is not close.. it is exactly what i have quoted from bobatkins an written in my first reply.
no need to repeat it
That's exactly what I was thinking
Sorry for the repetition, I did not read the quoted text. What astro said about lens compatiblity between Nikon and Canon has nothing to do with DX/FX or EF/EF-S compatibility, only with FBD, which is a different story entirely.
In the Canon system the EF-S stands for short back focus...
Actually, the -S in EF-S stands for small image circle. Yes, I know Wikipedia says it stands for short back focus, and Bob Atkins and lots of other sources do, too. But they're wrong.
Citation? I know incorrect information gets disseminated pretty rapidly and thoroughly on the internet, but do you have any citation for the correct abreviation?
