I do a lot of hiking and backpacking. I am currently carting a D7000 with an AF18-300 (I do not want to have to change lenses in the field).
I am looking to replace my gear and want recommendations to get the same quality and flexibility, but with a lighter load. Together the lens and camera are about 5lbs. That's a lot to carry around your neck for 8 to 10 miles or longer.
