Originally posted by waterfall Oh my 15 works at cold temps. I am just a bit concerned about moisture condensing inside the lens and camera when they come back inside. The freezer bag trick buffers the camera from interior air but the lens was assembled in the tropics and there will be water vapor trapped between lens elements. Dew point here this morning is -33F and the temp is now -36F.
Wow, that's impressive! I don't often see people posting from somewhere colder than here. Admittedly, I have only had mine in use down to the mid -20's. Anything colder and I can't seem to use my hands well enough for photography if I'm out for very long.
I've never had any real problems with condensation and have definitely never seen any inside the lens for what it's worth.
The coldest I have ever seen it here (Gunnison, Colorado) is -37 F a few years ago. Brrr!
