Juan, I was looking at Tomosy again, and he notes that persistent problems with properly adjusting the meter on an SRT might be caused by yellowing optical cement that keeps the CdS cells on the penta prism. They are glued with Canada balsam and he recommends cleaning the Canada balsam off with acetone and re-cementing them. Since this is not in the optical path of the camera (only for measuring light), he says that regular clear glue should work fine if you don't have Canada balsam or some optical cement. |
