Wind and Water Resistant Layer
Think about a top layer that includes wind/rain pants as well as a jacket. For warm jackets people usually think about down fill, but also consider some new synthetic products like Primaloft® and Thermolite®. Check with your favorite outdoor sports store to purchase.
Finally, don't forget about your feet and your head. Wear winter weight hiking socks with insulated hiking boots. Top things off with a gortex hat that covers your ears.
What about the camera?
Bring extra batteries cold weather can temporarily kill battery life, so bring extra batteries in your jacket so you can swap out cold batteries for warm ones when necessary.
