I have had the PEN F (microscope model) and the two lenses for 5 or 6 years. The lenses both look very clean. The 70 still has the gold import sticker on it. The apertures seem to be a bit slow to return to the full open position after the DOF preview button is released. Both probably need CLA. I think the lenses are suffering from long term storage. I once entertained the idea of using the lenses with my u4/3 cameras, but I already use my CV 75mm lens and don't really have a need for them. I have always been fascinated by the PEN F cameras, but realistically don't have a use for them. Any ideas what to do with these items?
