Verdict
The Pentax SMC DA* 200mm f/2.8 ED [IF] SDM is a very welcome addition to the Pentax lineup. The
performance is generally on a very high level. In terms of resolution and contrast the
lens is able to produce very good results straight from the max. aperture setting.
The level of distortions is absolutely negligible and vignetting and lateral chromatic
aberrations (CAs) are not overly field relevant. The quality of the bokeh (out-of-focus
blur) is very decent. However, there are also flaws. In critical scenes (extreme contrast)
the lens shows a rather high amount of purple fringing and longitudinal chromatic aberrations
(LoCA), colored out-of-focus halos, are also higher than average. These two issues do probably
originate in the rather old base design of the lens dating back to 1993. The mechanical
quality of the lens is absolutely exceptional thanks to high quality materials and seals
against dust and moisture. The new ultrasonic AF drive (SDM) works like a breeze - it's both
fast and almost silent. All-in-all a quite sound offer although a comparatively expensive one.
