Why is there such a big difference in the price of ptz for photography?

Good shelf carbon fiber material is good, light and strong, and hardware (various knobs and screws) are well made, which will not become brittle in winter and will not become loose due to long-term use, and can still maintain a fairly strong locking force after several years;

For example, domestic shelves weigh 1.5kg, with a load of 8 kg, and some high-end shelves of Gitzo weigh 0.9 kg, with a load of 12kg.

Pan-tilt is a problem of locking force and damping uniformity, which is actually the degree of accuracy. A good tripod head can lock more than 8 kilograms with a weight of 300 grams, and a bad tripod head will sink more than twice.

And sometimes you don't need 100% lock, you can lock it by letting go, but you can swing the camera by hand to adjust the position, and a good pan/tilt can do it. No matter what angle you swing the camera, the strength is uniform and adjustable, while a bad pan/tilt is either too loose or too tight.

After you adjust the camera position, the camera will not move when you lock it, while the bad camera will move and destroy the composition when you lock it.

There is also the reason why the domestic price is too high. For example, in Amazon, the shelf Yuntai is much cheaper than in China, with more than 900 in China and more than 600 abroad.
