it is steady... very steady

the gimbal though a little stiff moves quite smoothly, would have liked to move it slightly further but the setup doesn't allow, reasonably balanced

the legs of the Benro come with spikes which you have to attach

much easier to focus when the tripod is steady

tripod cost Benro C4580T $495 AUD

never having owned a lens this big I didn't know what to expect, the sigma 50-500 is like a feather compared to this tank of a lens, the tripod I had was a manfrotto 190XPROB

so for $725 I think I did ok

will keep you posted
