Okay, despite the chance of making a Jackass of myself ... I have a question about use of the H3D-II/31 on a technical camera using T/S.
This came about because Mark K asked me to try my new 31 back on the Rollei Xact2. Normally I don't use the 31DB on the Rollei because I also have a H3D-II/39, and that's the back I always use.
However, neither Mark or I can recall actually seeing examples of the reported micro-lens color cast issue from a H3D/31 posted anywhere.
Is it an issue with all lenses? Or is it a W/A issue?
I tried it with Rodenstock 90mm APO digital lens @ f/32 and 1/125th using consistent strobes to light a color chart ... and induced severe Tilts and Shifts in a couple of different torture configurations ... and neither Mark or I could detect the color cast issue.
So, the question is ... how should the test be done to check for this? What needs to happen to see the color cast?
Any help here would be appreciated.
