ivor said:Can anyone advise what is the max weight that a Gitzo Tripod (Max 2.5kg) with Giottos Ball Head (Max 6.5kg) take??
As far as I understand, ballhead can take 6.5kg, but your stand is only rated up to 2.5kg. Then how can a stand that take max of 2.5kg, able to carry 6kg of weight, exceeded 3.5kg.
In order to maximise your ballhead that can take 6.5kg, the stand needs to be at least able to take 6.5kg. The stand would not be able to take anything more that 2.5kg.
And can I mount a Canon 10D w/Batt Grip and a Canon EF 100-400L, and still be relatively steady.
You have already answered the first question yourself in the 3rd paragraph. The setup is only as strong as the weakest link. Just bear in mind that the load rating provided by the manufacturers always have a safety margin, so that the tripod will not just collapse if you put 2.6 kg on it.
I don't understand the question in your second paragraph. Did someone make a claim that a tripod rated at 2.5 kg load can withstand a 6.5 kg actual load when fitted with a 6.5 kg rated ball head? Can you provide the reference to that claim? If not, then this question has no basis. Even if someone made that claim, it should be clear that such a claim is not valid.
Just calculate the total weight of the equipment that you need a tripod for, and then compare that with the rating of the tripod and ball head. The tripod should be able to take the weitght of the equipment plus the weight ofthe ball head, and the ball head should be able to take the weight of the equipment.
If the load exceeds the manufacturer's specifification but only marginally, the best is to try it out at the shop before you buy. As I said above I don't think in such a case the tripod would just collapse under th increased load, but it may start to loose stability as the load increases because of the higher centre of gravity of the whole setup.
If this thread degrades into a follow-up debate from Terence's sales of his tripod and ballhead, I will close this thread immediately.
Thanks.
