A very good 18-135, as a little soft beyond

Contrary to what the previous reviewer, there is no stabilizer on versions for Pentax already fitted with a sensor stabilization Viale: Good there is a good chance that the two would have misheard

This goal is very compact and light enough compared to ration expansion. The consideration being modest opening but in the standard of this range.
The pictures are excellent to 135mm, soft enough beyond. A great alternative to 18-135, with a scarcely less quiet autofocus and certainly more reliable than the Pentax SDM device
