To Nikon F users: large black marks in prism finder
Hi. I have received a Nikon prism finder (i.e., non-metered) from a very reputable second hand camera shop that offers return privileges. The finder, externally, looks good but it has two low internal horizontal black marks in the same horizontal axis of the glass (each appears to be ~1 x 4-5 mm), in addition to multiple other, much smaller, black spots. The two long marks cannot be focused (i.e., they are not sharp regardless of any distance set in the lens --while the smaller ones look distinctively sharp). Does anybody have experience with this kind of defect (particularly the fuzzy marks)? Are the marks simply detached black paint that can be easily cleaned by a professional or something worse? I have the option to return the finder if this would not be something fixable at moderate cost. Thanks for any opinions.
