Im finally turning a film slr into digital, but need some help!!

so im finally turning a film slr into digital. ive looked for this for while but no luck. i get why. its a great idea but actually doing so is a lot of work and hassle. its free if you have all the things but its time consuming.

alright so i had a canon eos 1000fn or something like that. took it apart now i just have the barebones. have a working sony compact point and shoot camera, dsc w70. took that apart cleanly.
now the idea is to isolate the sensor, get rid of the old camera housing, and make space in the slr body to fit it all. i dont want the little zoom lens to be in it like i want just the sensor to be out and taking pictures. i took the sensor out of the lens casing and now im wondering what my next step is. im going to put everything back together except the lens to see if its still working.

when i put the tiny 1/2.3 sensor in a casing of a full frame camera, what should i do? where do i put it? do i need like a focal reducer so the lenses used are not going to be super tele? perhaps a magnifier that would make the sensor appear bigger hence reduce the crop factor? something?

That sounds like a fun idea, farabi.

I think you should see if the point and shoot camera works without the lens connected. If so, then you have a feasible system. See an example of what I'm talking about in Sony Cyber-shot and Canon EF Hybrid.

It's not so much where to put the sensor, but how far to keep the sensor and the lens apart. A camera is fairly simple, based on the concept of a pinhole camera. How far the pinhole is from the sensor determines the focal length.

Don't worry about the focal reducer or the sensor size just yet. Move your lens forward and back relative to the sensor and see where is the optimal focal length and focus range. Then based on that observation, determine how far you want to mount the Canon lens mount from the sensor.
