Nikonos Lenses on Nikon dSLR? in Nikon Posted September 24, 2012 I, too, would love to see a way to adapt Nikonos lenses to my DSLR for underwater use but so far there's no real solution. I measured using a ruler the flange distance on my NikonosV and it was close to Hugh Scarlett's 39mm (above). To make a Nikonos lens compatible with a Nikon-F mount (46.5 mm; ref: wikipedia Flange Focal Distance) you would need a 7.5mm spacer adapter. I haven't found such an adapter. Even if i did, it would be useless on the NIkonos 15mm lens since it is meant to be in contact with water and does not work in open air. Maybe, someone knows the mm to add or subtract to compensate for density of water. Then the challenge is to fit the 15mm in a housing and still have access to the focus and aperture controls - this getting messy real fast. There is an existing adapter for the Nauticam underwater housing for the Nex5 (mentioned in this thread). That's great and exciting until you find out the crop factor is 1.5 (not sure of this - I thought I read higher), the amazing 15mm becomes an ordinary 20mm. Plus you have to go manual controls. Nope, not there just yet but it's encouraging that there is one adapter. Hopefully, one will become available for Nikon.
