I'm looking into the most economical way of getting hold of a 300/2.8, zoom or prime.
The best bet at the moment appears to be Sigma's 120-300/2.8, but I'm getting lost in the versions.
So far I see old models with and without OS and new models with and without OS.
Either that, or people are just rubbish at marking up the proper name.
Also I see reviews for the 'IF' and 'DG' variants, but IF is internal focusing and DG is digital - we're not going to be seeing anything other than that are we? They're all DG and IF surely?
I was specifically looking at a copy on a UK site, MPB photographic.
Can anyone help out understanding what versions came when and whether they're any good?
