Why not a Gitzo GT1531? it supports 8kg and weigh much less than the 3531.



Weight rating is a deceiving number. The 3531 is "rated" to 18kg, but you wouldn't want to mount 40 pounds of equipment on it; it wouldn't break but wouldn't be stable either. In the same way, a 1531 could in theory support a 300 f/4 and 7D but the stability and performance would be greatly compromised. The 3 series Gitzos are made for lenses 300mm and up. 2 series, 200mm to 400mm max. 1 series tripods aren't meant for use with telephotos at all.
