The GT3533LS is from Gitzo’s large systematic line of tripods. The previous tripods that I have tested performed brilliantly, and this 3 series one is not exception. The stiffness and damping performance is excellent and the size and weight are on the low end for this style tripod. Gitzo makes so many variants of the systematic tripods though, that this tripod isn’t that different in terms of weight than the thicker-legged GT4533LS.

The stiffness and damping data are the averages of 10 trials for each measurement. The reported error is the standard error, except in the case of the damping data. I have set the error in the damping at 10% as the standard error metric does not appropriately capture the error in fitting to the data. All of the reported specifications are measured, with the exception of the weight rating. The tripod is measured at full height, with the center column down.
Example data for oscillations about the vertical axis of the tripod:
Data all looks good. Excellent stiffness, good damping.
Example data for oscillations about the radial axis of the tripod:
Definitely hitting the right resonance, but the damping is so high that the oscillation doesn’t look so clean.
