I'm looking at buying a new tripod. My question is:
Why, when the manufacturer gives a max load capacity, do they also give a "up to xx mm lens"
For example, I am looking at the Gitzo GT1531 Tripod and it says it supports a max of 17.6 lbs. Then they proceed to say "for DSLRs with 135mm lenses (up to a 200mm maximum)"
That makes ZERO sense to me. There is absolutely no way a 200mm lens and DSLR body will weigh anywhere near 17.6 lbs, even "pro" models of said equipment. So, they must be blowing smoke up someone's skirt in one way or another.
The way I see it, max load is max load. If it can't support bigger than 200mm lens for some reason (off balance weight distribution?!) then they have no business claiming a 17.6lb load bearing spec.
If someone can solve this mystery, please enlighten me
