I distinctly remember in the years leading up to the release of the K1, several posts with lists of DA lenses that had been evaluated (either film or the Sony bodies) for use on the FF sensor. I have spent some time here searching for those posts, but am unable to find them. So, could someone help me out - I guess my searching skills have gone into the crapper.

The 40 limited is OK stopped down a little bit, DA 70 maybe just a touch worse and the 15 and 21 aren't wider than APS-C. I think the 35 is an APS-H crop for the most part?

The only one I've used on a K-1 is the DA 40 and it is definitely usable but the corners are a little weak.

I started using the DA40 on the K-1 before I bowed out of Single-in and none of the cropping I ever did was for the corners. Put a good enough subject in the middle and nobody will look in the corners anyway. They are irrelevant.

I agree. The DA40 is a lens to shoot subjects, and the subjects are usually nearer the center. I really like using the 40 on the K-1. Actually, I like using all five of the DA quintuplets. Even in crop mode the 15 and 21 look better on the the K-1 than they did on the K-3.

To quote myself: "The DA40 Limited on FF is a joy". Even the corners are quite good in my shots there.

Da 50 1.8 works fine, just soft in corners wide open. Not too bad, gets way better stopping down
