The Benro GH2 is a very sturdy gimbal head designed to support up to 22kg, which should pretty much cover anything you could plausibly mount. I'm sure some of you are disagreeing, and if so, I guess this head isn't for you. But for anyone else, that's like three Canon 800mm f5.6 lenses mounted to three EOS-1DX bodies with a couple extra kilos to spare so, friends, it's enough. Some cosmetic wear, including paint loss and coating wear, but function is excellent.
