Analog to Digital Hack ?

Hi folks:

I have a really interesting analog camera made by Rollei. This is one of those classicly overdesigned German cameras with tons of features and accessories.

One of the neat things about the Rollei 3003 is that is has interchangable film magazines that allows users to have multiple film backs which could be exchanged mid-roll. This gave you the flexibility to shoot a scene in color, black & white, slide film, print film, whatever. See the attached link to view Photos of the SL 2000 and SL 3003 cameras at the attached rollei collector web site to see the camera http://www.rolleiclub.com/rollei/sl35/models.htm

Anyway, it occured to me that one of these backs might be modified to accept a digital sensor. I have no idea how to do this, but would love to get advice from anyone who might know how. Please post if you have any ideas.

Thanks

Theoretically there would be no real problems.
However, a chip would have to be found that covered 24 x 36 mm which might be difficult, is there one this size on the market?
If the chip were smaller then not all of what you see in the viewfinder would end up being in the photo.
This could be corrected by a magnifying lens in front of the chip. This of course would be difficult, as there is very little space in there, and would certainly add considerably to the cost.
Or a blanking mask of the correct size could be laid on the lens of the viewfinder....
The other effect of using a chip smaller than the film format would be a telephoto effect. If, for example, the chip covered only 12 x 18 mm, a shot through a 50 mm lens would look like it had been taken through a 100 mm lens.
This might be fine if you are trying to avoid buying a telephoto lens, but one of the major reasons why I love my 2000's is a very large and heavy lump of glass that cost an arm and a leg, that has got Zeiss Distagon written on the front, with a focal length of 15 mm. It would be a real shame to have this turn into a 30 mm jobbie!
Then the film transport would have to be put out of action, but as the camera already allows you to do this for multiple exposures, it should not be a problem.
And then what would be the story with the automatic exposure ? Without the relevant information, retro engineering could solve the problem.
Even a battery pack could easily be adapted to hold the power supply.
My winter projekt might very well be the construction of a digital back, the way to start might be to use the guts of a digital camera.......
Funnily enough, a few months ago, I contacted Rollei in Germany asking whether they had anything in the pipeline: the idea, they seemed to think, was good, but stressed the fact that the 2000/3003 has been out of production for more than a decade and was thus no longer 'supported', no plans, therefore, to produce a digital back, AT THE MOMENT !
Rollei have brought out a fair number of retro, special edition products in the past and do not forget that the original idea for the 2000/3003 came from an individual outside of the company.
And, in the meantime, Rollei have turned themselves into the world leaders in digital photo technology with the digital back that they make for the 6008: I think that the chip that they use is 56 x 56 mm. So the know how is definitely there.
Perhaps if we could gather together 500 people who were each prepared to put $1000 on the table up front, the Rollei could conceivably be motivated into producing 1000 units..........
Stay in touch, Power to the Net!!!!!
