Hey all, made some pictures with today with my 45mm Contax lens and Techart adapter and this weird ring started appearing. It's not really vignetting in the way that I am familiar - it does not happen with my 55mm 1.8 or the 90mm Zeiss Sonnar mounted on the same adapter, so I'm inclined to think it's lens specific but not sure. I hadn't noticed this in previous use with this lens, and I don't know what could have changed it. It happens at all shutter speeds with efcs turned on and off and it gets a little more pronounced with a smaller f stop as you would expect things to come in to sharper focus. I tried removing the lens hood and UV filter just in case that was somehow showing up even though it never did on the film camera - but that didn't change anything. I'm aware it could be some bizarre refraction issue or something given the beach scene, but it happened last night and this morning on the beach and again not with the other lenses. It's weird.... Any thoughts appreciated.
