In the digital age, professional shooting does not use UV filters, which affects not only sharpness, but also other indicators. But amateur photography is inseparable from it, and its main function is to protect the lens.

Imagine the best test indicators obtained by manufacturers when developing and producing lenses without UV filters. So why do users blindly believe what UV manufacturers say? The value of UV filter only accounts for a few percent of the lens price. How can we improve the shooting quality? If UV filters can improve the shooting quality, then it is not the manufacturers of UV filters who make money! Instead, lens manufacturers embed ultraviolet filters into their products.

Personally, I don't need professional shooting, portrait, landscape, artificial light original shooting and so on. Use (a tester) occasionally when shooting and playing.

Understand this truth!
