Sony has announced a new 10mp digicam using a CMOS APS-C sized sensor. Check out the preview at Imaging Resource. http://www.imaging-resource.com/PRODS/R1/R1A.HTM Sony claims a very short backfocus of 2.1mm on the R1. Isn't that just one of the problems that Leica is trying to solve on the MD?
Obviously the lens on the R1 is designed for the sensor, so it must give better light transmission than current 35mm rangefinder lenses. But I can't say this for certain. Perhaps Sonys chip solves the problem. As Sony sells their sensors to other manufacturers, perhaps we will see a rangefinder design using it. The crop factor is 1.67, I think, so it is not the greatest.
Just a quote from Imaging Resources review of the R1: "By contrast, the R1's optical system has a back-focus distance of only 2.1mm. This should translate into noticeably lower chromatic aberration at wide angle focal lengths, and in fact, we saw very little chromatic aberration with the R1 our test shots. (There was a small amount of chromatic aberration present, but it was quite a bit less than we'd normally expect on a high-end "prosumer" digital camera.) The DSC-R1's lens also showed considerably better corner sharpness than we're accustomed to seeing from cameras in this price range."
Looks promising. Am I missing something? I posted this over at Leicas Digital Forum as well.

here's the diagram. it's a lens based solution.
