Not only how skinny the little section is as Jon mentioned. But the quality of the connections on the leg. There are cheap section connections that will hold 50 pounds no problem, but at the same time wiggle like crazy. In this case the number of sections wil greatly reduce/increase the ammount of wiggle it has.
And the farther you extend the center colum the more of a monopod you have. totally defeating the stability the 3 legs give you. go all the way and you realy have nothing more than a monopod clamped to a tripod.
As above. I wouldn't worry about extending the center column a few inches or so, however.
There are certain photographic TRUTHS which have to be accepted on faith before you can advance as a photgrapher:
All four section tripods are worse than horrible.......except for Gitzo which makes theirs' with divine intervention.
All uncoated filters are useless.....except for Singh-Ray who made a pact with the Devil to bypass the laws of physics and light. (It cost them plenty, though, which is why they have to charge so much).
