Stopped down one stop, on my 645z I have found this lens to be very sharp at all focal lengths, with a small drop-off at the long end. Build quality is excellent. If you are coming from 35mm, it's big and heavy.

Hood rattles but good lens!

Cleaning the sensor of the Pentax 645z is a such an ordeal, that I decided I would just keep this zoom on it. The glass is very beautiful and sharp. I normally shoot in studio at F8-F11, and for my purposes, its the best purchase Ive ever made.

I love working with zooms, and this is my main lens. Very important for me is the short focusing distance. The lens is SUPER sharp. The colors are great. There is nothing I dont like about this lens. I would highly recommend it!
