Hi All, I just got a very mint used 120mm Macro lens for my new-to-me Hasselblad H2 and I've been experiencing a strange issue. Sometimes, not often, when I turn the camera on the lens and the camera are not communicating. I'm able to set the aperture to any setting I want, despite it being a max f/4 lens. The autofocus also stops working entirely. If I dis/reconnect the lens, it's back to normal and often stays that way until the issue crops up again. I've cleaned the contacts with an eraser head. I don't have any q-tips or alcohol right now (i'm at the coast) so that's as far as I've gotten. No errors showing on the camera itself. Has anyone had this issue or might now what the culprit might be? Thank you!
