Purchased for WR feature, more modern optics and coatings, newer autofocus mechanism, compact and light weight. Much sharper at extremes of focal length and wide open apertures than my earlier telephotos. Good value for money. Meets my essential criteria perfectly. However - can hunt, pass and return to desired focus point, resistance to turning stronger in focal length ring / manual focus ring, needs to use centre spot focus point for birding.

The lens is highly sharp, keep the aperture at 4.5 for sharp images. Stability is no issue on a Pentax, hand held day or night is easily achieved with this lens. The auto focus is very quick and if your Pentax is setup correct then this lens will be on your camera for the majority of the time.

New KAF4 mount works with DSLR models back to the K3 but not before. Updating the K3, K1 cameras firmware is essential too. Extremely fast AF. Very quiet also. Lens is pro-sumer level, not pro level image quality but the AF makes all the difference. Getting the action shot is much easier and more reliable with this lens. Well done Pentax for this great new lens and new mount.

would be more appropriate to review this later as I have not had a lot of time to play with it yet. My trial shots with it are excellent. Very easy to mount on my camera and easy to set up. I can not comment on durability as I have not had it long enough. There is nothing negative that I can say about this lens.

Just love this lens. The image quality is amazing and it has super quiet auto focus as they advertise. Best lens I have ever purchased.
