Decentered lens fix?

[Denton]

I have a 21mm F4 M mount skopar which is soft on the left side, but very sharp on the right side at f4 and even smaller apertures. Any hope for a repair? My guess is cheaper to buy a new lens. Seems unlikely I can sell it. In some cases you might not notice, but the difference is quite dramatic in the same image. I believe this lens has always had this problem but I didn't inspect the images after purchase.
Suggestions?

Focal Point lens repair. Did great job for me on Mamiya Sekor lens separation... took it apart, recemented it, and set it up on a collimation bench. Not cheap, but less than another used Mamiya Sekor Press 75 would cost and that without certainty of encountering similar problems.

My 25 is soft on both sides on digital, one more so than the other. I needed a screw mount so the need has passed.

He who buys CV needs to think more carefully.
