Some reports have also shown that 17-40L is sharper than the more expensive 16-35L.
Some 85 1.8 owners argue that it's as sharp or sharper than the more expensive 85L.
It's widely believed that the 70-200 f4L and 70-200 f2.8L are both sharper than the more expensive 70-200 f2.8L IS.... etc...
Yet people still purchase these "not as sharp, but more expensive lenses" by the droves. There's a lot more to a lens than just absolute sharpness. I've taken shots with the 50L that were so sharp it could cut you good. So I have to question how sharp does a lens have to be before someone is totally satisfied? And even if the 50 1.8 is sharper at certain apertures, is the out of focus blur, color, contrast, aperture design, CA and flare control, AF mechanism and build as good as it's more expensive brothers? Can it stop up to f/1.2? Image quality is not determined by sharpness alone.
But ultimately, you have to be satisfied.

fantasic post, man. i wish more people shared this mentality. i'm so effing tired of hearing about sharpness.
Yes, no quality issues here
