Is the lens of the camera necessary?

The lens of the camera is necessary. Without a lens, the camera can't image. A good lens can follow, and a new camera can follow in the future.

Lens maintenance:

(1) Photographers are not allowed to disassemble the lens at will. If there is a problem, they should go to a special maintenance department to repair it. Otherwise, it can't be recovered after disassembly and can't be adjusted accurately. The damage caused by lens will affect the imaging quality of lens.

(2) Don't wipe the lens with rough and unclean objects.

(3) When brushing the lens surface with a lens brush, the brush should be kept clean, and it is not allowed to touch the brush by hand. When the brush is dirty, it should be cleaned with alcohol in time.

(4) Do not add lubricating oil to the adjusting ring of the photographic lens at will. So as not to flow into the lens and contaminate the lens surface.

(5) When not shooting, the focus ring of the lens should be adjusted to infinity, the aperture should be fully opened, and the push-pull zoom ring and macro ring should be retracted to improve the seismic performance of the lens.

(6) When the photographic lens is not used for a long time, it is best to keep it in a glass sealed vessel filled with desiccant or sealed in a plastic bag filled with desiccant.
