Nikon W-Nikkor-C 2.5cm F4 LTM Leica Mount Lens Clean with Finder
This is a rare lens and the finder is even more rare. Add to that the original cases and we have a nice set here.
The lens is in excellent condition with light wear. The glass is clear with a slight haze around the edges. The aperture does not fully open at f4. I cannot confirm this but I think that the lens was made that way; the lens could actually be f3.5 or f2.8 but Nikon was not happy with the performance at full aperture so they limited it. That is my guess.
The finder has a couple of scuffs on the front glass but I do not notice this in use.
The lens has the rear cap only. Both of the cases show moderate wear but are structurally sound
