I'm reviewing the f4.2-6.5 Aspherical variant. It's a polycarbonate lens with a metal mount in KAF2 fit. The lens does not rotate in zooming, it focuses well on a K-30. The FOV of 42-315 mm is a nice range and (unlike most) this lens is better at the long end than the short. To get the best out of it you need to stop down to f8 or f11 and I'm quite happy to use it instead of the current 50-200 mm kit lens because it's better. Downsides are noticeable but not objectionable barrel distortion at 28 mm and a slight tendency to flare.
