You always hear that a crop sensor makes lens X like lens Y on a FF sensor, so I wanted to compare a 50mm on my 7D with an 85mm on a 5D. Focus in both cases was on the water glass. Same exposure, f-stop, everything else. Used a tripod to guarantee the same POV. No post-processing. I thought it was interesting, and helpful to a right-brain type person like me that has to see the difference.
And there was more difference than I expected somehow.
And the pictures themselves are nothing special just my deck.
