ownership:I own this lens
compared to:Minolta 28/2.8 AF
Sony 30/2.8 DT SAM Macro
Sigma 50/1.4 HSM
price paid:229 USD (KEH - used)
positive:- fast maximum aperture
- good build quality
- sharp wide open and very very sharp stopped down
negative:- screw drive
- focus ring rotates during AF
- not as well built as its bigger brother, the 50/1.4 HSM
comment:- Build quality is good, but at the lower end of the Sigma EX lenses, in my opinion. The focus ring rotates during AF, and is a little scratchy on my copy during MF.
- Screw drive is quick, but not as quiet or smooth as the ring HSM on the Sigma 50/1.4
- Sharpness is good wide open, a little soft in the corners, but usable. Stopped down, it's razor sharp. If you've ever used the Sigma 50/1.4, you know what to expect here. More than usable wide open, and damn sharp from f/2 or 2.8.

Overall, if you can get a good price on this lens, and you're using an APS-C body, snap it up. the new Art version of this lens is supposed to be better wide open (and has HSM), but is twice the price of a good used copy, and this version is more than capable of doing a good job in the hands of a good photographer.
