temperature problem under +3° C

[firstcamera]

Hello folks,

today i have tried to test the RED #48 in munich outside.
In munich/germany it was between -3 and +3 degrees celsius today.

After the Red was out in the cold for about 1/2 hour, the cam was not working any more (switched to on after 1/2 an hour in the cold).
There was just a strange image of bluish bars.
So actually the cam worked in terms of power supply and booting (the menu and the red logo were displayed normally), but there was no image on the CF-Card and on the monitor just the strange pattern of blue bars.

Once the cam was back in room-temperature-conditions for 15min., all was working normally again after a reboot.
We went out in the cold again with the still booted cam and after 15min. we experienced problems again.
Different problems, we got format errors.

Any more input from you guys about temperature conditions and the red cam?

Is there a possibillity to display the inner temperature of the cam?



Thanx a lot.

Cheers,

Did you already try covering the camera with something?

[Fredrik Harreschou]

Haven't you heard, you need the BLUE camera to shoot in sub zero ;)
Seriously, I hope this can't be as serious as it sounds. We have below zero six months a year here. What was the humidity inside/outside?

[firstcamera]

No, we did not cover the cam with something.
But I believe, it won´t help (the number 48) to just cover it, i think it has to be at least a heated barney.

But I believe also, there are more people out here in that forum they have tested the cam also in cold conditions.

Please post guys!

Cheers,

Emanuel

OK,
nice joke Fredrik!
But, did you shoot outside with the red in the six month of cold, where ever you based?

The humidity was absolutely moderate today!
I dont know the degrees exactly, but for me it was really dry day!

This should be a serious discussion!

Cheers

Was the cooling fan on? Try it with the fan turned off. The fan would pull the cold air into the camera making it like an icebox inside. Give it a go, it might help. :cold:

[firstcamera]

Yes,
the fan was working all the time the camera was not recording (normal)!
Could this be the solution?
Thanx for your great input!
This could really solve the prob i believe!
I will test this tomorrow.

Cheers,

Emanuel

Are you 100% sure the problems are actually temperature based? I've had issues that I was sure were temp/humidity based that turned out not to be. The slight temp difference in fan on/off isn't likely to 'solve' your problems.

Maybe there should be a system hysteresis warning as well.

Just a thought.
