CFV 100c and ALPA technical cameras (ALPA 12 STC, Plus, Pano)

Has anyone experiences with the combination of CFV 100c and ALPA technical cameras in terms of this small sensor format, shifting possibilities, color cast and compatibility with the latest Rodenstock lenses?

No experience with ALPA bodies, but I do use the CFV100C on a Cambo WRS-1600 with Rodenstock Digaron glass (23/40/90/180).  Corners darken on the 23 with a bit of a color cast which cleans up well with an LCC image; if any movement, definitely need the LCC.  The 40 is good without LCC, unless I am shifting/raising at the extremes.

If Steve Hendrix is around, he is familiar with ALPA and may comment.

Happy to lend my experiences, what would you like to know? The BSI sensor enables a better workflow and superior results compared to previous digital back sensors, in terms of color cast. Are there certain focal lengths you're considering? We can speak to this topic with regard to any current or relatively recent Rodenstock HR or Schneider Digitar lens, insofar as optical results, shifting latitude, etc.

The Hasselblad Phocus software has a color cast vignetting removal tool based on an additional diffuser shot file that works perfectly. (LCC above)

Color cast vignetting comme from symetrical built large format lenses used on digital backs (Phase One has a similar tool in Capture One).
Non symmetrical built ultra large angle lenses don't have color cast vignetting on digital sensors (for example Nikkor PCE 19mm also known as Cambo 19mm large format lens.)
