I'm going to Montana in November to accompany a hunting expedition into either the Gallatin Mtns or the Missouri Breaks of Montana. I have a Nikon D100 with 28-85mm and 80-400mm lenses. I need help selecting the following items and please keep in mind the gear needs to withstand extreme cold conditions:
1. Camera carry system (I'm thinking about the LowePro Topload 75 AW) because I need to carry a backpack for personal items.
2. Tripod- I figure carbon fiber is the best bet here for weight and cold weather operations. I need something I can strap to a backpack. Any suggestions on a particular ball head to get for outdoor activities?
3. Batteries? Where can I get more or can anyone suggest a better power supply system for cold weather?
Any other ideas or tips are appreciated.
