how do all the users of this lens find the AF on this lens? fast, slow? noisy, quiet?
why is this lens so "un-popular"? I mean 10-24 FL with a F3.5-4.5 is not bad at all.
in my limited experience it is not super fast, but not so slow that it bothers me. Then again I have not shot anything that is moving yet. I don't notice the noise.
It seems pretty sharp to me, I am happy with it.
