Alright, so I feel like I'm losing my mind now for sure. Yesterday I shot a test roll through my GA645 with varying filter/hood configurations and can't duplicate the issue I'm having. The only thing different in the tests is the film. The original roll I was having issues with was Tri-x 400 and the test roll was Arista Edu Ultra 100.

All three of the above were shot with my normal combo which is a rubber lens hood on the lens with a yellow Hoya filter threaded into the hood.
