Does anyone hike with SLR camera gear? Yeah I know, it packs on the pounds, but I'm going to do it and my mind's made up. Done it before, not for 4 months, but I'm going to go for it. It's 50% of my drive on the AT deu to a photography project im working on. Is anyone has, what tri-pod did you find to be the lightest but still sturdy enough to hold up an slr with decent lens weight? Nothing over the top huge...
