Looking for suggestions I guess
While photographing the lunar eclipse my camera shutter started to sound loud.
Also the displays started to get weird as well. 
The lens was stiff. 
This was all after about 1 hour+ in -12 to -15F weather. 
Windchills were worse but I think that was only affecting me ... :)
I've photographed in subtemps before but not for this duration. 
Is there something I should be doing or using to prevent this?
Thanks for any suggestions.

Maybe strap on one of those chemical hand warmers? The grease in the shutter assembly and lens aperture are not designed for that cold with that long duration.

Thanks - didn't think things thru that night and after I noticed things going downhill I packed up that camera.
Does the heat applied cause any condensation in the lens or camera?

Never used them, so can't answer but I wouldn't think so.  Probably not anything to do with your problem but here is a cold weather test.  One thing about mirrorless cameras and the sensor always on, lots of heat.

The displays get weird because the liquid inside them freezes. They are actually fine and will recover. The cold temps are great for the sensor though as you can push your ISO much higher before noise creeps in when the sensor is very cold. If it's a DSLR (without an EVF) I would not heat it to keep the sensor nice and cool but just be prepared to rotate the batteries through and not worry about the rear LCD. If it's a mirrorless then you may have to do something to heat the back of the camera so that you can see either the LCD or the EVF. I would not put the heat near the lens.

Here’s a link to an article on the subject:

You can also Google this for others:

“camera use in subzero temperatures“
