comment:I use this lens on a daily basis to shoot portraits of my family and friends.

I find the biggest advantage of this lens to be the expression. Both the 50mm and 28mm Minolta has a more grainy look and more unnatural foreground and background rendering. (I tried two 28mm lenses and three 50mm lenses) The Sigma is simply by far more natural looking and is completely devoid of the grainy feel.

A huge surprise was to me the speed and accuracy my A300 and this Sigma 30mm offers when it comes to auto focus. I find myself only longing for more senors, as I trust all the ones I got. I can even focus in seriously dim light with the center sensor, and hit focus. (iso3200, f1.4, 1/15s)

As I have stated in the forums, I have sold all my zooms and only shoot with this lens. I even got rid of the 50mm f1.7. This Sigma simply killed all the fun with the zooms and the old primes, as they simply could not touch this Sigma. I do not need any USM using Bibble with this lens, still getting incredible detail.

My only real complaint is the limited macro. I have taken a handful images with some mild issues with washed out colors under backlit conditions, and a lot with no such issues at all.
