There are digital backs that can be applied to certain film cameras.
But.....they start at about $20,000.
A simpler and cheaper solution is to get a film-strip scanner.
Such as the Konica Minolta Dimage Scan Dual IV.
If you shop around, you can find it for just over $200.
I realize this may not be the correct place to ask this question but I will try anyway. My wife uses a Nikon N90 SRL film camera with an AF Nikkor 24-120mm lens. And although the camera weighs a ton, she loves it and she is very reluctant to switch to a digital SRL Nikon model. Can you have the best of two worlds? a converter that turns the N90 into a digital camera? Perhaps I am dreaming here, but if anyone is aware of such a device/attachment, please let me know. Thanks.
