I think it's quite a good zoom. It's a zoom, of course, and not a

Hello all,
I would like to add some longer lens to my small collection. The
longest lens I have is my favorite M 135/3.5 - sharp and small. But I
need some more. I could buy mint Sigma 135-400 quite cheap (350$),
but I can't test it before I get it. I am bit afraid of its weight -
is anybody here
If you can spare $2000, the Sigma 120-300/2.8 AF.
Otherwise, the Tokina 100-300/4 AF, which is said to be even better than its
manual-focus forebear. Big and heavy, but a fine performer.

I've never used the autofocus version of the AT-X 100-300/4, but it
must be fantastic if it's better than the manual focus version.
