    Zeiss Super Ikona IV in the cold

    While shooting today in cold and snowy Yosemite, I discovered that the shutter is slow in the freezing cold. About 27 degrees F. I had a CLA done a year ago on my Zeiss Super Ikona IV. I thick the grease in the shutter is too thick for the shutter to work properly

    this happens with any camera -- my olympus XA froze up on a bike ride a bit ago, I've seen Nikon Fs freeze up -- 27 is pretty cold -- keep the camera inside your jacket until you shoot so it stays warm enough. -- you don't want it so cold that it gets misty from precipitation when you take it back in the house either.

    if your camera does freeze up DO NOT FORCE IT. Just put it inside ur coat and let it warm up.

    If you are going to use it in the freezing cold a lot, like that upcoming treck to the South Pole by ski pulling sledges (take lots of vitamin C!!!) you an have it weatherized with thinner lubes.

    Another thing to watch out for -- frozen film can break, and generate static electricity that leaves lovely flashes on your film, so wind slowly in the cold.

    Or use a Prontor shuttered camera. Prontor shutters are designed to run dry and should not have any oil in the mechanism and so cannot freeze up.

    I recently had two rolls have run into bad static problems in -7C weather, (which isn't too cold). I've had to stop shooting outside at dawn and move up to 11:00 AM for the rest of the winter with film.

    Only a few parts of the shutter mechanism need to be oiled. And certainly not greased. There are watch maker's oils of very high quality (Moebius 9010 comes to mind) that really never freezes. However if even that low-viscous oil enter the shutter blades your in for trouble. If this is an oil issue you are having bad luck or a bad CLA (wrong oil). The mechanism can of course also be slowed down by humidity in it before being brought out into the cold.

    I have never once had trouble with a camera freezing up. I routinely photo at night in temps well below zero F, sometimes as cold as --42F. If a camera is having problems at what I consider a fairly warm +27F, something is wrong with the camera.

    Could be that the CLA didn't involve wide temperature range lubricants.
    Proper CLA should guarantee reliability down to at least -10°F.

    When I wrote my first post in this thread I also put a self-CLA'd Zeiss Ikonta in the fridge (-18C/0F). I took it out of the fridge just right now. This was CLA'd without the superb Moebius oil and worked ok at 1/25s. Faster speeds were no problem, slower a bit erratic though [The main worry now is the amount of frost that immediately stuck on the lens and elsewhere, haha.... ]. Well it was a test.
