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!

I use the DA* 60-250 on FF and debated cutting the baffle six years ago when this first came up, but since i use it for shooting portraits and concerts where the edges simply don't matter, it works fine. Ditto the lens hood. It is a great performer on the K1 - I suppose I should try it on the K3iii
