Great topic and I'd like to share my latest discovery: Tight fitting gloves available at the hardware store, elastic fabric with a neoprene/rubber grippy palm. These are cheap and great for photography as you can still feel all the little buttons, great from about -5 C up (but you'll need to put your hands in your jacket every so often to warm them). I also use them (another set of course) when I work on my car.
I have several different types but this picture gives a good Idea of what I mean. For photography purposes I use an all-black set.
