Summary: I bought one of this lens for my brother for his new a65 and after trying it out, I decided to get one for myself. It is very quite (relatively) in autofocus and I love that I can do direct manual focus without moving any switch. I haven't done any extensive test on it but from what I can see with my naked eyes, it is far better than the 16-105mm I had before.
Summary: I replaced my 35-90mm lens that seemed to have stripped gears. When I first tried this new lens I thought it was not working since I did not hear it working. When I looked through the viewfinder I saw it was working and it seems to focus quicker and very quiet. Works great and telephoto range covers any thing other than when needing a major telephoto lens.
