Wide-open performance isn't too good, and the improvements between f/8 to f/16 are confined to the centre of the lens.

Fringing test

There's fringing at the centre, and it gets considerably worse towards the edges, but recent Pentax SLRs can correct lateral chromatic aberration.

Distortion test

Distortion control is excellent, with just minimal warping. Were it not for the superior Sigma lens, the Pentax would just edge its way to the top.

Image test verdict

It's a shame that wide-open sharpness and control over chromatic aberration are poor, because otherwise this is a fine, solid lens.
