I’ve been following the “digital film” saga for years. There’s been at least 4 failed attempts to get one working, and one hoax. Nikon even filed a patent for one of their own at one point. But besides those early digital film hybrid cameras, none have ever really made it. At one time I thought this was an amazing idea that was bound to happen at some point. Now, I’ve pretty much given up on that ever happening.
There’s a multitude of problems with the whole idea, and no ideal solutions to most of them. But a photographer by the name of Robin Guymer actually seems to have cracked things to find a way that works for him. He’s repurposed an old Sony NEX camera into a digital back for his 35mm Nikon FE.
