Verdict
The Pentax DA SMC 17-70mm f/4 AL [IF] SDM is undoubtedly the most desirable standard zoom lens in the current Pentax lens lineup. The resolution characteristic is very good without any significant weakness. The vignetting and distortion are about average for a lens in this class. The lateral CAs are relatively well-controlled although you may spot some traces in field conditions when using wide-angle settings. The quality of the bokeh (out-of-focus blur) seems to be very fine albeit limited compared to fast prime lenses naturally. Contra-light situations are handled fairly well with comparatively underdeveloped ghosting problems. Typical for most Pentax DA lenses the build quality is on a very high level. The fast and near-silent ultrasonic AF is also a very welcome new feature. All-in-all a very harmonious package selling for a very fair price of around 480€/US$.
