Everybody has advised you on several different things about a tripod, but nobody has advised about the support capabilities of the tripod. The tripod [b wrote:
and ball head[/b] should hold, one and a half to twice, the combined weight of your camera and largest lens.
Cheap is not good! A 2K camera and a 1K lens falling from a cheap tripod results in a 3K loss.
I use it for moon shots and macro with my Canon EOS 7D and 5D MK II and an EF 100-400mm f4.5-f5.6L (sometimes with or without a 2X teleconverter) ring mount. I also bought the 322RC2 ball head to go along with it. They're built like a tanks & they'll last forever.
