Desperate but not serious
Apparently someone in Europe is still trying to make digital backs (or sorts) so you can turn your 35mm camera into a digital camera

It seems a good idea.

There could be a niche market for such a thing, but really I think there are plenty of purpose made digital cameras that do a better job if you want digital and film cameras are fine as film cameras for us Luddites that like that sort of thing. In the coming decades using film will be as obscure and quaint and odd ball hobbyist as the handful of people doing daguerreotypes or wet plate photography today .
"Quaint" isn't the first word I would use to describe my adherence to film, but I'm good with it. There is no "progress" in art, only change. The film medium suits me and what I do. There are contemporary artists/photographers addressing contemporary concerns with "quaint" processes. Take a look at Sally Mann's wet plate work, for example. But please, no digital vs. film nonsense; whatever works for you!
I am a film guy myself that own and use countless film cameras of all vintages and only own a small digital camera that was gifted to me in 2007.. no need to get up in arms as a Retro-Grouch.

Ken Rockwell will still say film beats digital as to image quality.

Seems sort of like an adapter you can use to play DVDs in your VCR.

Basically, the image is focused to a ground glass/focusing screen
The ground glass is focused by a lens into a relatively tiny sensor of unknown quality.
The problems with this approach, besides the huge size are:
- The image is focused to a ground glass: This introduces vignetting, the grain/surface of the focusing itself is introduced into the picture, and various optical aberrations of course. It also won't produce the same image as film; there's a difference between the depth of focus allowed by a focusing screen versus a film emulsion.
- An additional lens, introduces an extra optical system for further image degradation.
- Tiny sensor probably is not optimal for the (reduced) amount of light captured by the combination of focusing screen + optical system -- there must be a light loss of several stops there.
Yet, we have digital backs for medium format cameras.
I was really thinking in terms of 35mm film cameras.
If I had an investment in Hasselblad bodies and lenses I would consider Hasselblad’s 50 MP digital back. Is anyone else currently making digital backs for medium format cameras? I am not really up on that market segment.
