Recently acquired from ebay, Pentax ES II, cosmetically and optically like new EXCEPT that Viewfinder blind is locked shut, and nothing I do (new batteries, fiddle the shutter-speed dial, battery-test button, exposure-compensation-dial, hitting it, praying) has any effect. I COULD just gestimate the distance frame bygolly, and shoot, and with that lovely Super-Multi-Coated Takumar 1.8/55, it would probably come out with a good photograph, ... , but with such a beautiful TTL, it seems a shame.
