Looking for a handy tripod, I came across the Gorillapod series. The "Gorillapod SLR" should then fulfill his duties with a Canon DSLR + lens on tours. Thank goodness I have previously tested once at home. Even with a small fixed focal length (50mm) I had difficulty aligning it or add put it stable. The stability of the unit can be described as poor. The experiment with a telephoto zoom I broke directly.
Perhaps it can be good to wrap a bar / a branch ... But I have not already tried. Useless as Rig for DSLR in my eyes. Maybe more for compact or small ActionCams
