Hi Stefan,

It looks like a combination of a very dirty sensor and hot pixels.

I get hot pixels on my leaf Aptus 75 when I uses shutter speeds between 20 to 30 seconds.

The hot pixel problem has diminished greatly with the new Leaf Capture v11.2 soft wear.

Cheers

Simon

Hello!

Well I don't know so much about Leaf so thought it pertinent to not interfere.

However, I would very roughly guess it was a duff calibration file or misuse of calibration file by hardware or software.

Best,



David

Quit the software, unplug the back, dump the gain file from the app folder and start again.

Yair responded immediately to my problem with a private email, suggesting to erase the gain file. can't really tell whether it solved the problem, as in the meantime my dealer (photo universal) sent me  loaner back, mine went to repair or rather exchange. this is what i call fantastic service. Herr Kleiber from Photo Universal suggested this back was DOA, as it showed strange color shifts before.
