This is an interesting story because when I tried to research this underwater digital camera (Nikon DCS 425) I could hardly find any info online. It seems that this model was produced for the US military/intelligence organizations and initially even its existence was denied:
“The Nikonos RS was the World’s first underwater SLR camera, capable of going down to a depth of 100 meters without special underwater housing. Searching Google at the time (May 2005) produced absolutely no hits for the digital Nikonos (DCS 425 and DCS 435). Absolutely nothing. I then sent an e-mail to Kodak, asking for more information. Their reply:
“I’m sorry but those cameras never existed here at Eastman Kodak. We never made cameras for that specific use. The information you have is incorrect.”
Strange, because I was certain the camera existed. Asking another Kodak source, I was told: “I think the issue is who they were made for”.
In other words: The camera was made for some US military/intelligence organization. Kodak Professional support, which sent the above reply, probably didn’t even know that such a beast existed. (It later turned out that the camera probably never was a big secret after all. Read on for more info..)”
Read the whole story @ Nikonweb.
More info on the film version Nikonos RS available here (very expensive on eBay).
