Well I am glad yet another hiker is packing the big camera gear into the wild! More good pictures in the back country is always nice!
At times I regret moving to SLR because I have managed to get my pack to about 20 pounds base weight even with all the extra stuff I bring and then I have to throw 8 more pounds of camera gear on me! But when you get back home your glad you did!
I suppose if I had my choice I would bring a fixed 24MM lens and a longer reaching one such as 100-400MM but for my camera 24MM is pretty wide.
My only real question with that is I often take photos making slight adjustments by zooming in a bit and I question how often I would do those shots if I had to change the lens. It's one thing while your camped and taking photos but when your on the move all day and especially in a highly scenic area where your taking out your camera like every 20 seconds then it will not go so well.
