Now that this tripod head of the company is a very good Sirui, I need not say more here. For heavier cameras with a larger zoom lens of the G-10X is not the right choice. I have a camera with battery grip (1100gr) mounted with a Tamron 70-300mm (790gr). This clearly shows the boundary of the head, because nevertheless both the Friktionsknopf and the locking knob has been tightened, the ball head moves too easily and the image detail moves repeatedly. Here I can only recommend the larger version G-20X. This can not be shaken even by larger weights and only a few euros more expensive !!!
