Upload & Sell: Off
Isn't it time for some company out there to manufacture digital backs for 35mm cameras? I read up on the subject, and there were a few failed attempts in the last decade. I feel now, however, technology is where it needs to be to make this happen.
I see two possibilities. A universal cartridge with a digital sensor that is inserted in to any 35mm camera instead of film. Of course, this won't give you any feedback until you upload the exposures to your computer. Here is a design concept I found on the web:
The other solution would be to replace the original back with a new one, which has a digital sensor and an LCD screen on the back for preview of captures. Many cameras already have replaceable "data backs", so this should be pretty straight forward. There would have to be a selection of backs for different camera bodies.
Even if the sensor was "only" APS-C, this would be something I'd buy immediately. Production costs shouldn't be too high. After all, it would be a much more simple design than for instance a full NEX camera, so the cost should be below that of a new NEX 5N.
It's going to happen, sooner or later, so make sure you have a copy of your favorite vintage camera body when it does, because prices will sky rocket. I just wish some company would hurry up and get it done... like NOW!
What are your thoughts?
