Is there any difference in stability and weight-bearing ability between the Gitz o 1325, which has three leg sections and no center column, and the Gitzo 1348, w hich has four leg sections and no center column? The tripod would support my Wi sner 4x5 traditional and the MF system that I have been contemplating (right now , the Pentax 67-II is in first place, followed by the Contax 645AF and the Mamiy a 7-II - vastly different cameras, I know!). Thanks.
