Verdict

It is a little tricky to find a verdict for the Sigma AF 150mm f/2.8 EX DG HSM APO macro - as mentioned above the sample lens suffered from a rather extreme degree of decentering which pollutes the resolution potential of the lens (on the left image side) - a rather worrysome quality control issue.
Assuming a good sample the lens can show a very high performance straight from the max. aperture with a peak performance at or even beyond the resolution limits of an 8 megapixel APS-C sensor. Chromatic aberrations are quite negligible, distortions are basically absent and vignetting is very low. The bokeh (the characteristic of foreground and background blurr) is very smooth with pleasant out-of-focus highlights. The mechanical build quality is very high. The HSM AF drive is virtually silent but the focusing speed is rather slow which is typical for most macro lenses though.

So in principal the lens can be highly recommended - see also the Nikon review of this lens where it performed stellar.
