Not that big a deal Cotty, it's also called a "semi-silvered" mirror. Lets some light thru, reflects some. A lot like the "one way" mirrors you've seen. Here's a page on the Canon F-1 that shows some advantages and disadvantages: http://www.cameraquest.com/f1high.htm
Here's one from Edmund that shows a Pellicle "beam splitter", works the same but has superior qualities. http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productid=2044&; CFID=1941248&CFTOKEN=ba8b82d60fb65f7d-6C95818C-3048-41AD-8422E529AC5CC370 Sorry about the long URL, you'll have to copy and paste it.
