Hello everyone! I should be heading to Sweden for a student exchange programme in the early half of next year, and I'll definitely travel up North to capture photos of the aurora borealis aka northern lights. My equipment will be a D90 + kit lens + Tokina 12-24 F4 lens. I was wondering how well will DSLRs - lens and the camera bodies - perform at sub-zero temperatures and would like to seek feedback from fellow CS-ers on this. I'm seeking recommendations too for a cheap tripod that can support the weight of the D90 + Tokina (it's heaver than the kit lens) and survive the cold harsh climate too.
Also, I read somewhere that you need to store your equipment in a bag with the outside temperature in order to prevent condensation, how is this done? You go outside, gather a bag full of air, then put your equipment inside? Many thanks in advance!
