I'm looking on the 'net to find reviews. Here's what Amazon says about
the AF version for Nikon:
Sigma's 28mm f1.8 II aspherical lens has an uncommonly bright f1.8
aperture, yet at 2.4 inches and just over 10 ounces, it is extremely
compact and easy to take with you. With its two compound aspherical lens
elements and floating focus system, peripheral flare is almost
completely eliminated, while image surface curvature often found in
close-up photography is corrected. This lens has a broad variety of
applications and is dedicated to Nikon AF SLR cameras.
And, here's a link to a photodo-type rating:

Overall grade is 3.4. Not bad really for 170$.
Hope this helps.
