Gitzo is right that this tripod can RELIABLY STABILIZE only upto a FOCAL LENGTH of 300mm. Please note the portions I have put in caps, since it is not the weight of the lens you have placed on the tripod that matters, but the view-angle or the Focal length of the lens, that is of even more importance.
I understand that now that view angle/focus length is more important. I have a 1.6 crop factor camera and I want to buy my first tripod. My longest lens is the Canon 70-200 IS 2.8.
In order to find the right tripod do I look for a tripod that can handle a focus length of 320 mm or for one that can handle 200mm?
What happens if I use a 1.4 converter?
