Verdict

The Sigma AF 70mm f/2.8 EX DG macro is capable to deliver exceptionally sharp results throughout most of the aperture range. The bokeh (out-of-focus blur) is very smooth and buttery. Typical for macro lenses it also produces a negligible degree of distortions. On an APS-C DSLR vignetting is nothing to worry about. Lateral CAs (color shadows at the image borders) are comparatively high for a fix-focal lens but still fairly low in absolute terms and not really field relevant. The AF performance of the lens isn't overly impressive - the accuracy is fine but it is both slow and noisy. Other than that the build quality is on a very high level.
