Thanks Jon! I think you are right.


I think I should return it now, I was just testing myCanon EF 70-200mm f/2.8 L IS II with my oldCanon EF-S 55-250mm f/4-5.6 IS and the 55-250($230) Was slighty sharper at f5.6 in the corners, then my 70-200($2300) at f2.8.


I do not think it should be that way, should it? A $230 lens beating a $2300 lens for corner sharpness? Looking at the#mce_temp_url#seems to say this as well.
