Verdict

The Pentax SMC-D FA 100mm f/2.8 macro is a very good lens which is capable to provide very high sharpness till f/16. However, the resolution could be a little better at f/2.8 whereas the contrast level is already excellent here. The bokeh (out-of-focus blur) is very smooth and buttery - an important characteristic for a macro lens. CAs and vignetting are very well controlled and not really field-relevant. Typical for macro lenses it shows an absolutely negligible degree of distortions. In relation to its fairly high price tag (~550€/US$) the build quality leaves a little bit to be desired - the lens doesn't feel quite as substantial as its predecessor and the lack of a focus limiter is a bit disappointing because the AF tends to hunt quite a bit.
