Marumi 77mm DHG Super UV Filter

OVERVIEW

A UV filter protects your delicate and expensive camera lens from dust, fingerprint, scratches, or, more importantly, from physical shock and damages. It does, however, sound like the functions of another filter, Lens Protector, because a UV filter plays a role in lens protection and avoiding negative influences caused on images by Ultraviolet lights.

So what's the difference? UV (Ultraviolet) radiation affects image quality in the form of haze, which impairs contrast and sharpness in the image. UV filters are long pass filters that block & cut the UV wavelength range and transit the visual spectrum, the light we see in our eyes.
