Gitzo pulverises basalt, melts it and adds some pixie dust, then spins it into fibers. The result is a glass/metal composite fiber that is woven and laminated with epoxy into a tube structure. Then Gitzo PR takes over...
This being stated(the makeup of basalt)I have a question.
First I have two tripods(one aluminum,one carbon fiber).From what I understand(I may be wrong)wood tripods allow less vibrations to reach the tripod head than the above.How would in comparison a tripod with all those
elements(of basalt) compare in this regard-worse,better or about the same?
The ones listed at B&H are pricey for the load capacity-would it be any real
improvement from a scientific viewpoint.
