In the Pentax Square in Shinjuku, Japan Pentax has revealed a special 50th Anniversary edition 'Design Study Model' digital SLR with the tentative name of 'Asahi Pentax'. This prototype camera is based on the K10D (as is obvious on closer inspection) but has a very different viewfinder, which is of the same design as that found on the very first Asahi Pentax from 1957, the first Japanese SLR with a fixed pentaprism viewfinder. Note that there are no plans to put this camera into production, rather it is a celebration of Pentax's 50th anniversary and their long contribution to SLR photography.
