So I have my beater pair of x-metal Juliets that I recently placed some lovely Fruby lenses in. My problem is that the left lens isn't sitting quite right... The opening to the left orbital, the where the gasket sits is slight off, with one side being higher than the other when the orbital screw is tightened. The edge of the lens is clearly visable and doesn't sit perfectly in the frame. This gives a bit of flex to that part of the lens I notice when cleaning it. My question is, is there anything I can do to fix/minimize this? Is this a fairly common problem?
