>>3021998Well it's designed for crop digi, so it's a reasonable question.
>>3021975Yes, it works fine, just gets a little smeary towards the edges, but even the far corners are acceptable by f/11.
It's just a plain EF mount, not EF-S, so it doesn't protrude into the mirror box.
The EF-S 10-22 works on full frame too, but you have to pull off the EF-S plastic baffle on the end of the lense. Full frame coverage from 13mm onwards.
