Why do top movie cameras only rent but not sell?

For fear of technology leakage. Top cameras have absolute technology, and these technologies are just secrets that camera companies don't want to reveal. After all, they make money by technology.

Moreover, at present, materials are scarce and the production cycle is long, so it is more expensive. For example, renting IMAX cameras will send people to follow them to prevent the machine from being damaged and leaked.

There are only four IMAX cameras in the world, and they are only rented and not sold, with a monthly rent of 6 million. It is also jaw-dropping to see director Guan Hu talking about this news in an interview. However, what is even more frightening is that every time you shoot from one angle to another, the bombed scene needs to be recreated, because there is only one IMAX camera.

It can be seen how much money the director and producer of Guan Hu spent to make this film. But their efforts have paid off. Ultra-high definition image quality, ultra-high contrast between light and dark, giving 800 ultra-high image quality. It also brought a super shocking audio-visual experience to the audience. In this regard, only going to the cinema to see this film is the best tribute to him.
