Sorry for replying late. Thanks Zos and John for the feedback! Now I've looked better at my Pentax K-30 viewfinder, and a similar pattern emerges like on the new Pentax K-3, therefore I would assume it's not a "fingerprint" but the actual pattern as Zos suggested. Regarding it's "fingerprint"-like shape, it's actually more like a "wavy" form, similar to a moire pattern: https://encrypted.google.com/search?q=moire+wave&tbm=isch So I assume it stems from the grounding pattern on the focus screen, which I thought should be without any actual pattern (i.e. grounding with a motion in many directions, not in circular motion, or the like.) Regarding the "spot" I can see in the viewfinder, I intend to first try to "blow" it away with a blower (not caned air), and not fiddle with the focusing screen for now. Either way it doesn't bother me right now. Any considerations in this regard (i.e. cleaning the focusing screen without actually removing it, assuming the dirt is on the "exterior")?
