Possibly ... but where did you hear this? I have yet to see a single complaint about this lens, aside from it being expensive.
Personal anecdote, Bobby. I had a killer copy that I stupidly got rid of, then wanted to buy it again. My third copy after that is a keeper being the closest. (To keep exchanging became like Sisyphus.) For whatever reason, the Gods didn't want me to get another lens like the first one that I let go.
