It is a great lens on APS-C, and its 3 aspheric lenses give it sharpness into the corners, which is great.
Probably still one of the best relatively compact Canon APS-C standard zooms.
Things I personally do not like about this lens is the for me distinct sharpenss zones, which I reckon are caused by teh aspheric lenses. Sharp into the corners, yes, but clearly to me with a wavy sharpness pattern from center to corner, 3 areas actually, which is why I think it is casued by the 3 aspheric lenses, each optimally correcting for a different part of the frame. I am probably too much of a pixel-peeper, however.
One other thing I do not like is the way this lens renders, colourwise. Yes, that can be fixed in postprocessing (or even in-camera with specific jpeg settings). This is something I find is true for all Canon EF-S lenses however, and it is really a personal preference, nothing else.
HTH, kind regards, Wim
