Good afternoon brains trust!
I'm in the process of sorting out my Bronica GS1 to part out and noticed that my 100mm f3.5 lens has some weird banding along one edge. It's not a reflection and can be seen less obviously when the front cap is off, but there are definitely two "rainbow" bands present.
Is this lens separation or something else entirely? I've never experienced this with any other gear, so it has me rather stumped . . .
