Hi Group,

I'm shooting with an H10 back on a FlexAdaptor on a Horseman 4x5, running OS 10.4.8. I am shooting a metal screen sifter against a white background and am getting a green/magenta shading on the screen. It looks like green/magenta chromatic aberration but it was not visible in other shots shot with the same lens (Caltar 210 f/5.6). Any ideas what the problem might be? Thank you inj advance.

This sounds like there is a mismatch between the sync signal and the shutters movement.
For example that the short circuit the lens does during the lens open phase end prematurely.
This means that the sensor is exposed to light even if the back are doing read out since it thinks the capture is done,
Try a different shutter/lens to verify.
