I was wondering if the issue would be due to the slight damage on the rear element of the lens. When I dial up to f/2 the issue is mostly resolved. Or is it the fact that I am not focusing correctly or exposing due to the large aperture?
I recently bought a rokkor 58mm f1.2 on ebay for 260, and the guy said it was dreamy wide open. I thought, this couldn't be an issue with the lens. I knew the rear lens would have slight marks on it but also knew it should effect image quality.
I was looking at the glass and though it was a little dirty and took it apart to clean. Put it back together and it was the same. I was thinking, maybe I should flip the rear lens and see what happens, and Voila! fixed.
Here is a sample wide open now, I am currently trying to get an EE-S screen for my 5d to fix MY focusing issues. But this is what I got so far. A LOT better!
