Hello.
first happy new year to everybody!!!
I bought an unknown Petzval lens last year. I tried it with film and i noticed it had a kind of glow and was a bit off focus.
Today, i tried it again more seriously with a LensAlign target, it is really hard to focus. It is glowing a lot even if i reversed the rear group like a Dallmeyer.
The lens is rear focusing by around an 1 1/2". All the others lens i tried today are in focus...
What could be wrong with it?
