How to protect the lens

Install a UV mirror: In order to protect our lens, we usually bring a UV mirror (installed outside the lens of the lens) when buying a lens. The UV mirror can Protect our lenses from being contaminated by sand and dust, and some UV lenses are also helpful for shooting (such as ND lenses).

Install a hood: In addition to installing a UV mirror, we will also install a hood outside the lens. The hood can not only prevent the lens from bringing in too much light and ultraviolet rays when shooting, but also Protect the lens. If the lens is dropped, the lens hood will hit the ground before the lens and act as a buffer to protect the lens from being hit too hard.

Clean the lens regularly: No matter how well-protected the lens is, it still needs to be cleaned.
