Can anybody comment on the Gitzo Studex 320 tripod? For or against? Likes and dislikes, etc. I'm 5'11" and would want to use it in the field for long exposures, sometimes under windy conditions, with a 35mm body with lenses up to 70-200 f/2.8 or 300 f/4. I would have to backpack it most places I go. I have an opportunity to purchase one from an estate sale that comes with a Giotto MH-3000 panning ball head, but it's not convenient for me to see it, I don't think it's made anymore, and I don't know much about it. It's reportedly in good condition.
