Wow are there really people complaining about the 135L and linking comparisons with the 200 f/2!?!?!? $6k vs $900, I'd hope to god the 200 f/2 was better for costing 5x more.
I thought the fact that the 135L is one of Canon's sharpest lenses and best values was just common knowledge, never ever seen anyone complain about it. And test charts can only tell you so much, try real world use and then come back and complain. I mean for you to say that I can only believe you've never actually used one, or if you did it was a bad copy.
