Verdict

The Sigma AF 60mm f/2.8 DN may be an unambitious design but this is not a bad thing since the comparatively slow max. aperture (for a tele prime lens) keeps optical obstacles to a minimum. Consequently the lens is capable of delivering ultra-sharp results - at least in the image center. The outer image region is very good at f/2.8 and even excellent around f/5.6. The lateral CAs are well controlled which contributes to the high sharpness perception. Distortions are usually nothing to worry about whereas vignetting is a bit high at fully open aperture. You may also spot a little bit of purple fringing here in extreme contrast situations. The bokeh is generally pretty good although the out-of-focus highlight discs can show onion-like substructure.

As far as the build quality is concerned - it is surprisingly good given the low price tag although admittedly we would prefer the old EX DN design with its rubberized focus ring. Thanks to an internal AF the physical length remains constant and the manual focus action feels smooth and without wobbling whatsoever. Sigma's new linear AF motor is moderately fast but almost silent.

When looking at the sum of its characteristics and the extremely low price tag, the Sigma is a pretty safe bet indeed.
