I have a Nikonos III with the 35mm and 80mm coming on Monday! Why? Why not! and it was offered a good price.
Brother Butkus has the manual on line so I won't be flying blind. The seller is sending some lube and a new gasket.
Anyone out there shooting underwater with one of these? Any suggestions on how to test for water tightness? I'd imagine that if the sealing surfaces for the lens and the case are good and the gaskets look undamaged all should be well, but the O rings for the wind/shutter, aperture, and shutter speed probably aren't readily "checkable." At the least it will be a truly "all weather" shooter.
