I just had my Yashica-D cleaned and serviced by Dean's Photographica in Idaho - excellent, quick service I might add. Today I was browsing around his website, and found this page. I thought others may be interested.
Check out the "Old Stuff (Classic Cameras)" page, then click on the "The Dirty Lens Test (Just how bad is too bad?)" Thumbnail towards the bottom of the page. Interesting stuff.
