I would greatly appreciate advice on buying a new tripod. I think I am looking at Gitzo tripods. I am 56, 6ft and have back and neck problems which mean that I am very limited on walking. Many days I am down to 50yds before needing to sit but on other days I can get maybe 400 yds. I am also limited on what I can carry together with my stick seat. I made a bit of a mistake and bought a second hand Manfrotto/Bogen 058 which is as solid as a rock and weighs as much as a fair sized one! This means that I can only really get it a few yards from the car. Obviously I need something lighter. The advantage of the 058 was the height it can get to without extending the column. I have trouble bending to look through a viewfinder and crouching is completely out of the question so I need as much height as I can get. The biggest lens combination I am likely to mount is the 70-200VR plus 1.7TC and I would like to get more into stitched panoramas using the 17-55 DX. I will be mounting my D2X on the Markins M20 together with the Manfrotto 438 levelling base. Can anyone give me their recommendations from the current Gitzo range please? I'm getting completely lost in the various ranges and leg combinations.
