Old lenses only sharp in the centre?

Well, it looks to me like you've nailed it! Well done. I thought it might be a loose ring.

Your examples at 2.4 and 4 are a really tough test and you shouldn't expect super sharpness wide open from this lens, especially near the edges, although it performs better than many. I'd like to see how it performs at f8+ (full frame plus crops).

Well, you did a very good homework Laughing

You haven't to repeat this job, unless you need it again. All of us are in the same way, I think.

Enjoy this nice lens. Good luck.
