I guess I should rush right out and spend more than the cost of a good EF-S zoom lens on something I use perhaps 3-5 times per year, to take pictures of inanimate objects. And some occassional night shooting outdoors. Right?
Or will my 40+ year old, cheap-at-the-time, well made, all aluminum, bought at Target, $30 Velbon tripod do the job? Although it can't get lower than about 2 feet, and certainly not upside down like the Gitzo, it works very well for my purposes. I used to mount a pair of 35mm cameras with long lenses on them to it. I also think it could take more beating than a Gitzo, too. I did make one modification, however. I added a screw clamp to it so I can move my L-bracketed camera on and off quickly and easily.
The video clearly demonstrates the difference between a cheapo tripod and a good one. If I were looking to make a living with a camera, or frequently used a tripod, yes, a good, sturdy, lightweight tripod is a necessity. If I thought a good wind can blow down my latest pride & joy 5D3 with some L glass on the tripod I have, that would be more than enough cause to replace it. My only fear is the clumsy klutz that I am (or someone else) will trip over it and there goes the show. But that's one of the things my home owners insurance rider policy covers.
To me, rushing out and getting an expensive tripod is no different than rushing out and buying a bunch of lenses before one even has fully understood the basics of photography... Getting any tripod or extra lenses should be one of filling a real need, not "oh, you must get a ...".
