I sent my camera out on a rental and when it came back the PL mount was so tight I couldn't open it to seat a lens. I have removed the screws and tried to loosen the mount. As soon as I tighten the screws the mount wont open or close. If I loosen (by unscrewing the entire mount and moving to a different ear) the lens doesn't sit tight. If I loosen the screws on the mount slightly the mount will move again but the mount isn't tied into the camera tightly. I tried to adjust the little screw under the one ear and that doesn't seem to help it either.
The 1st AC is no longer in the country and I don't know how to reach him to find out what and how he made the adjustment.
Anyone have experience with this?
