While people who sit behind desks all day might have the luxury of browsing MTF charts or have the time to notice that this lens might not be quite as sharp in the corners wide-open in a laboratory as the huge 24-70/2.8 GM and even bigger 70-200/2.8 GM, for those of us who have to shoot and to produce saleable photos every single day instead of just talking about it, this lens lets me do it all. I've had no problems licensing photos to major international pharmaceutical companies for thousands of dollars each — and those were shot with a kit lens! The only people who blame bad photos on their lenses are bad photographers, or people trying to sell you expensive lenses.
