IQ180 quality problem - purple / cyan

Postby NN634510337582534739UL » Sat Jan 09, 2021 7:25 pm

Hi, I use a 645AF with a IQ180 and have the following problem:

When I take a picture with a strong light source, like the sun or a candle in the dark, I get some strange image quality problems.
Sun: The sun brings out a purple/cyan reflection at open aperture. The only way to eliminate it, is to darken the picture or juse a close the aputure.
Candle: when I shoot a candle, the whole dark space around get purple. Thats random. Sometimes like a cross, sometimes just one half of the picture.

Same same in LR and C1.

Sample pictures with: 180mm 2.8 CZJ Sonnar P6 (adapted) and Phase One 80mm 2.8. (it doesn't matter which lens I use, always the same problem)

Can someone tell me whats wrong?

Here are some example pictures (with exifs):
