Currently I own a manfrotto aluminum tripod and Manfrotto ball head niether of which I am really happy with. Though I can lean on this rig and it seems to support a great deal of weight, I get a lot of vibration from the tripod and the ball head is anything but smooth and it drifts slightlyafter I lock it down. I am currently shooting a Canon 50D with grip anda 100-400L---Not too much weight---maybe 8 Lbs tops. I do plan buying a 500 F4L one of these days, and I would like good support for it. I also plan on purchasing a Gimbal head when I buy the lens.
My real question is: What's the real difference between Aluminum, basalt, Lava and Carbon fiber. And does a couple of pounds really justify the cost??
Your thoughts are appreciated.
