I have other canon cameras that could be used with the shutter opened and digital acquisition with Magic Lantern via USB(with hacks).

But today I believe it is much better to use Digital cameras like the Raspberry Pi HQ cameras with good lenses. You don't need hacks, and the sensors come from recent mobile phones modules that have much better quality and technology than old camera digital sensors.

The lenses you can get for an SLR tho are much better than what rPi cameras usually come with. If you use film era fully manual lenses you can get amazing quality for next to nothing. If your shooting objects that are still, taking longer exposures or exposure brackets is trivial. I wish there was an GUI program for tethered cameras that still had an option to capture multiple frames each time you trigger it and average them for an output frame. It's strange that feature was removed, in the SD video era there were lots of options for that.
