What if the AF were in the sensor? There's a camera on the market now that allows you to change focus after the fact, so to speak. If they can do that, perhaps they can make a sensor that auto-focuses as a built-in feature. If Leica did that, they could use all of their old glass, all the way back to the Barnack cameras...😱.
No, the old lenses would not work, at least not as expected. The stereo base is tied to aperture, the resultant images are much smaller than the sensor, and the microlens grid must be in the proper relation to each lens. It would be possible to build cameras that can be used with one particular fast lens, wide open - but a M10 that only works with the Asph Noctilux and delivers a 1MP 4D image at a 200mm focal length equivalent almost certainly would be no hit, regardless of whether you can focus after the fact or not...
