This seems to be an intriguing combo for travel.
3.5 Pounds, Folded length is 22", max height is 62", payload is 22#s. Should hold a 5Diii and 70-200 just fine.
Only drawback for me is the twist locks for the legs, i was looking for lever action legs. The sheer number of tripods available is daunting.
