    Mechanical parts can fail in extreme cold.

    I wouldn't summarize those results quite the way you did---to me the big-picture result is that the differences between the cameras are small, even in a tightly controlled test with a lot of attention given to controlling other variables. It certainly speaks well of the Mamiya's performance, but I don't think it really militates for choosing one system over another in terms of image quality, for most practical uses.

    To be sure the Mamiya 7 is a wonderful system, and quite portable for its size; I don't mean any disrespect towards it or Chris Perez! But that same article actually tends to convince me that I'm not missing much by carrying around a Rolleiflex.

    I believe that a couple of spare batteries, in a warm pocket, would cover the cold issue.

    But then whether it is mechanical, or electrical, where are you finding a repair person out there in those temperatures?

    I have to mail mine off to someone who is working, I believe, in a nice comfy clean room.

    Sadly, there is no local repair mechanical or not, here.

    Desperation?? Wow are you deluded. It's a simple fact that mechanical devices can fail in extreme cold weather. Your hysteria does not change this fact.

    what would your suggestions be?

    PS, I am looking to combine an M6 and a MF rig to fit in a Billingham bag and be something that is always by my side.
    I haven't posted much and I haven't looked at the responses yet, but I would suggest the Hasselblad system. They're relatively small and weigh as much as a DSLR with a f/1.4 prime lens or fast zoom attached. You can pick up a 500 c/m kit pretty cheap. There are some things you need to look out for, though. The back might have light leaks because they're old, the shutters may be worn in the lenses (easily remedied with another lens), or the inserts might not match the film back (the film won't be as flat as it could be). They're relatively loud when the shutter is tripped so discrete street photography is out.

    If you need quiet, though, a leaf shutter is the way to go. I think the Mamiya 6 or the Fuji 690 (I think that's the camera and manufacturer) should work in a pinch. Not sure how much they cost though.

    Good luck!

    The only two cameras I currently own are an RB67 and a M6451000S, I drag along the RB almost everytime I go out and shoot mostly handheld with the multi angle grip. On the rare occasion that I need something lighter I take the 645, regardless of which I take my tripod a Bogen/Manfrotto 3251 is gonna slow me down.

    Hahahaha another problem in very cold condition is frozen stiff film putting undue stress on the advancing mechanisms n frozem weak batteries may not transport at all... Your motor drve may seize since it is lubed with oil.

    I had a problem with my RB once when camping in minus 10f, left the camera in my backpack overnight. I tried to advance my film... A mistaske i realized as soon as i tried. No shooting that day.. Besides it would have taken us hours to warm it to the point of no condensation.

    Btw a well cared for shutter won't fail because of cold unless it was lubed wrong. Most leaf shutters run dry, so nothing to slow it down.

    I can appreciate mechanical over electronic as far as repairs (in my shop) go.. But not as someone might have misconstrued as field service.... Yes your batteries would be dead as your fingers fall off.

    OK, for all those people that still do not believe in working batteries in cold temperatures, read this paper on Energizer lithium batteries that are readily available in stores. Yes, performance is less at -20C but these batteries are still far from dead at that temperature.

    This is type of battery that I use in my film cameras. The operating range is specified as -40C to +60C (-40F to 140F). -40C is probably pushing it for the winder (high current) but the lightmeter and shutter should be fine. But I will certainly not go out for photography at -40C (excl. windchill) so that's not an issue.

    Yes properly maintained camers is the key... Not many people have their equipment serviced anymore. They like to wait till it drops dead, then justify it was a piece of junk n buy another ab-used camera.

    Btw batteries have come a long way with lithion. They are real preformers. But other limitations contribute in cold conditions. ... Motors in auto focus, film transport motors, relays... Too many parts that can't run dry.

    I wonder what film was used on the moon? I read an article from a polar expedition that had serious problems with brittle film breaking while advancing frames. The camera itself had no problems at all.

    I think the main problem with mechanical cameras in the cold is not seizing, but slowing. I had an autocord tnat did that. if you couple that with no availability of a light meter in our "no battery" thought experiment, it becomes hit and miss what you will get. I like an electronic shutter because the springs are always releasing at maximum tension, so the slower speeds stay accurate in the cold. if the battery was really a problem, i could keep a warm spare in my inside pocket, but I have left the Bronica and its silver oxide battery in my car overnight at -12c and no problem shooting in the morning.
