ownership:I own this lens
compared to:Tokina 100-300/4.0 ATX
Minolta 75-300/4.5-5.6 D
price paid:Traded gear for it
positive:- Constant f/2.8
- When focus is correct, very usable wide-open, sharp from f/4.0 and on.
- Looks nice
negative:- AF is hit or miss
- Focusing ring gets in the way
- Zoom ring placed too far to the back of the lens
- Sigma says the lens isn't supposed to support my 7D and that re-chipping is no longer offered. It turns out it works just fine (except for the AF misses)
- ZEN coating is sticky rubbish
- Slow AF on the 7D
- Heavy
comment:Very nice lens. Well worth the Benbo 2 tripod and Sigma 75-300 APO lens I traded for it (the latter isn't compatible on Minolta DSLR's).

This Sigma is a far better lens than Minolta 75-300/4.5-5.6 D, but I'd say it trails the Tokina 100-300/4.0 ATX - both optically, and in terms of build quality. Both lenses are on the heavy side though.
