hrst, the point I was trying to make, and which you acknowledged, is the difference between telecine/datacine workflows and end products VS tradtional digital scanners.
Scanning has never been "hard", it has been incredibly expensive and remains so in a commercial/post-house environment.
Sounds like you have a nice setup, but you might want to investigate a non-bayer pattern camera without a mechanical shutter.
Stepper motors, an Oxberry Aerial Image head with 16mm and 35mm gates, a 3K (8MP) monochrome, non-bayer pattern camera, RGBI LED lamphouse, some custom software and a multi processor PC with several TB array.
I can capture .dpx or .cin or .exr up to 3K or linear TIFF 16 bit files.
Anyone can make one, given the proper motivation, but using it properly, for whatever discipline, is a whole 'nother ball of wax.
In any event, I should just read the posts and save my energy for some rapidly approaching deadlines.
