I agree! This is a very sharp lens. I had it on a K-3, and feared I would have to trade it when I switched to the K-1.

Then I saw a video on YouTube. Apparently the optics are designed for full frame, but Pentax put a baffle in the back of the lens to "neck down" the image circle. Following instructions on the video, I cut out the baffle and now I have a very nice lens for full frame. Moderate vignetting is easily correctable in post processing. If you do this, you will also find the stock lens hood is too long for full frame use. I just leave it off.

Thanks for the review!

Very interesting on the baffle, etc.

And my pleasure!
