I had an aluminium slim leg tripod, 20cm long when contracted, however it's not stable. When I release shutter from remote, the lens head shakes a little. And my other SLIK is just TOO huge for me.
I need a full size tripod which is 25cm long when contracted, so that to fit into my backpack, while stable enuf for my 1.8Kg (tele + camera) system for birding. Any recomendations?
