As the digital revolution continues, I'm wondering if the 35mm camera will still be in production in a few years. I'm thinking that the 645's will be taking the place of the high end 35mm cameras. Perhaps a film cartridge like the 35mm cartridges of today made for a medium size film, and new backs that will take that size film will be offered. Then your 645 would take either a film back or a digital back. Even if a new film cartridge was not introduced, the 645 might be the camera of choice in the future. Mass production of these dual format cameras would reduce the price and become competative with the standard digital format camera (based on a 35mm SLR of today) and would have more options. Either way, I look for medium format cameras in some sort to be with us for years to come, but I think the 35mm SLR is going to be a dieing format. That is unless some problems develop in the digital world that would cause people to want 35mm cameras. What do you think?
