EF and EF-S are 'compatible' but only in one direction. EF-S Cameras can take both EF and EF-S lenses. You can't go the other way; on EF Cameras, an EF-S lens

EF-S Cameras can take both EF and EF-S lenses. You can't go the other way; on EF Cameras, an EF-S lens will probably not fit and even if it does may damage the camera (i.e. mirror might hit the back of the lens due to clearance differences.)
- turtletontine 5y agoThere's a pretty simple reason for this: ef-s lenses are designed for a smaller sensor, so they only need to be sharp for a much smaller area. So you can make lighter and cheaper lenses. Canon doesn't want people putting ef-s lenses on full frame cameras and complaining that the image edges look like crap - because, well, they're not meant for that.
- I_AM_A_SMURF 5y agoDon't EF-S lenses need to produce a smaller image in general? I always thought that if you somehow put an EF-S on a full frame sensor you would get a circle image similar to a fish eye.
- turtletontine 5y agoHmm I doubt it would look like a fisheye. The edges would appear darkened and soft, and there would maybe be extra barrel or pincushion distortion.
