Can anybody suggest a compact but sturdy tripod for travelling? It will need to be able to support a 35mm rangefinder with a 35mm lens. Ideally, I would prefer one that has a min./max of approx. 30 cm to 150 cm., folds up to about 30 cm. and is fairly light. Basically, it needs to be small enough that it won't impair my ability to drink at a pub after an evening of long exposure shooting. Many thanks in advance.
