Hey guys, I am in the market for a new tripod, and am thinking of buying used on ebay. I see a lot of Gitzo tripods, and a mix of 3 sections and 4 sections. How do 4 section tripods handle night photography with really long exposures? I just feel I should buy a 3 section, but there could be a perfectly fine 4 section tripod I could be missing out on. Thank you.
