I just acquired a new (to me) Minolta XD-11. I love the XD-11, and this is my third and, by far, the best condition. It's super-clean, the metering is flawless, and the leatherette is like-new. The only problem is that the focusing screen in as dirty as hell -- in fact, it seems to be damaged and/or marked up. It's usable, but it's a little annoying since one of the great things about the XD-11 is its super-bright viewfinder. So here is my question: Is it possible to have the focusing screen repaired or replaced? I know that Minolta sold replacement screens when this model was still supported (and Minolta still made cameras) and if I could acquire one (or cannibalize another camera), would it be possible to replace? I have never serviced an electronic SLR, although I have serviced the frame-advance mechanism in some older, mechanical Minolta SRTs. Is this something I want to get myself into, or is there a camera service that can do it for me? In all other respects, this camera is absolutely perfect.
