The lens mount for EF-S is different than the EF mount. In that you physically cannot mount an EF-S lens on a full frame camera body.

This is because the distance between the rear lens element is farther back on an EF-S, and could actually come in contact with the mirror when the shutter is actuated.

You can mount an EF mount lens on a crop body camera, but not vice versa.

you will notice the EF-S lenses have a white "square" symbol on the lens and EF has a red circle, also on the camera body, this is to try to be a visual symbol that the two aren't compatible.
I didn't realize I needed to spell it out. If it doesn't work correctly, it doesn't work Troy.

Social Media elevates the absurd and mediocre to a point where they aren't anymore, and that is a tragedy.
