First I've ever heard of a 70-200 doing this, particularly as it has a fixed barrel length.
The barrel may be fixed, but the elements still move forward and backward. If you look in the back of the lens and turn the zoom lens, you'll see what I'm referring to (assuming the f/4 works the same).
That, along with you saying it was slow in focusing, makes me think they rented you a real lemon.![]()
I said slow-ish. It's definitely better than, say, the 18-200mm IS I had, but it's definitely slower than the 24-105L. That may be just because of the heavier elements it has to move around and maybe the physical distances the elements move are more? I don't really know but I can tell it's harder work - battery life is definitely less than I'm used to!
I guess it could also be just well worn from use/abuse. I wouldn't go as far as saying it's a lemon - the output is just fine.
