While Leica with the M has been the ultimate retro camera, many camera manufactures now are playing the retro card. Fuji in particular have been very good at this with some of the X cameras.
The last few weeks has seen more and more rumours spreading about a retro Nikon coming soon. Many have said it will be a modern digital Nikon FM. I have the Nikon FM2 and its one of the best all mechanical 35mm SLR’s available. Hopefully Nikon will announce it on Tuesday and we will know for sure.
