This may of interest. It's an interview with JP Beauviala from Aaton about the 4k digital magazine for the Penelope 35mm film camera.

It's high end kit, so I expect mostly rental houses will be buying it.

One difference is the CCD sensor, I wonder if this is one from the Dalsa Evolution? Handy that you can reduce the sensitivity to 100 ASA, much more sensible for exteriors, especially with an optical viewfinder.
