Frosty here three....

So cold some mornings I can see my nipples poking through my parka...

Please highlight in photo said nipples

Don't you mean your jumper
Thats a great shot it would make a nice X-mas card.
Do you have any difficulty with the lenses fogging up in that extreme cold.
I could'nt imagine living in thoses extreme conditions. Brrrrrr

ok here's the truth...
there's two ways to do this.

one involves ziploc freezer baggies, & taping/velcroing a Hotshot )or other brand) chemical handwarmer to the battery compartment, while shooting, Then you throw the sucker into a freezer baggie and suck out the air BEFORE bringing the camera inside. good for extended outdoor use. once your camera is cold, keep it cold till the shoot's done, no "in and out" to warm it up..condensation is your real enemy, not cold.

the other is to keep the camera in a hip pak under your jacket, take your gloves off, pull your camera out, fire your shot and put everything away before your hands get too cold. keep dessicant packs in your bag. get the shot and put it away before anything gets cold, and leave it somwhere warm and dry afterwards.

use everything on manual.I don't know how hard the cold really is on the lcd's, af motors, lubricants etc. (could be shortening the life of my equipment...)
but it does affect battery power and if mechanical things get to stiffening up, don't push your luck...everything breaks easier when frozen.

I have a parka that I bought two sizes too big, just so I could wear it over some camera gear.....

...and they still poke through that?
