"The is a great upgrade from a kit lens. Good focal length range, speed and macro ability."
"This is a great all aroud lens. Love the wide angle I get and just enough zoom for an alround."
"What you need to know if you have a k-10 is that you need the latest firmware update to make the autofocus work from the lens."

It is sharp enough, but my copy is not perfectly centered and the left of landscape photos is sometimes so-so. F/2.8 is appreciable and the bokeh is very decent. The HSM makes focusing very fast on the K-5.
Cons: the OS (stabilization) is useless on Pentax bodies (shake reduction built in the sensor), the lens is therefore a bit heavier than necessary, and something wobbles in it. Also the manual focus ring is not really usable (not precise enough). The AF/MF button is redundant with the button on the body. You cannot MF if it is on AF, even if the body is on MF. This can be a bit annoying at times. Also the filter is 72mm (thanks F/2.8!) and filters of that size are pretty expensive.
Despite those trifles, I couldn't go without it now.
