my first post here but I have been a passive reader since several years.
My main business is architecture photography and I own a quite complete set of Alpa Max, Rodie lenses, 645DF and an IQ180.
Now my very urgent problem and I hope to get help from the forum. Since 5 days I stay at Iceland (2 weeks) with my 4x4 recreation van. The island is a winter-dream - my 16th journey to Iceland. Everything is fine, but ....
The IQ180 fails after several minutes when I expose it to temperatures below -4 deg. Celsius. Then the battery icon on the back is blinking and shows an empty battery. But I have 7 fully charges P1 batteries, three Haenel chargers and one Canon CH910 charger. The batteries are definitively full.
My question to IQ180 users: did your back work at temperatures below zero? Does the darkframe-subtraction work at temperatures below zero? When making longer exposuers the darkframe is made round about only every 10th shot.
And the 2nd question: Do you have any idea how to solve the battery-problem?
In the last days the temperatures were between -4 and -10 deg.
Thanks a lot in advance.
