EXUS UV Mark II
Marumi EXUS UV Mark II The Marumi EXUS UV Mark II is a refined flagship model UV protection, especially suited to the presupposition that the filter shall be habitually attached to the lens. Corning® UV Clear Glass; Corning is a registered trademark of Corning Incorporated (Corning, N.Y., USA) Anti-static coating (ASC) reduces the reflection to under 0.2%, improved from the original's 0.3% (420-680nm average) High transmittance over 99.1% (420-680nm average rate), with UV Sharp Cut at 410nm The upmost coating technology implemented, twenty-two layers in total on both sides; ASC works wonders on the surface of glass. Dust and dirt adhered to the surface can be quickly and easily blown off. Water-/Oil repellent coating sheds water off simply also by the air blower. Nuisances such as sweat, skin crème, lotion, fingerprint, or compounded grease stains will be wiped off. Enhanced flattness and lens protection realized by adapting glass thickness 2.0mm Realized a thin frame to avoid vignetting Knurling embedded on the lightweight frame enables easy and smooth handling "Made in Japan" optical precision and performance What is the benefit of using a UV filter?Why do many photographers leave UV filters on their lenses more or less permanently? A UV(Haze) filter allows you to;- prevent or attenuate a specific range of ultraviolet lights that pass into a camera to restrain haze and glare- maintain image contrast and sharpness while reducing bluish color cast- protect your camera lens from physical damage and many nuisances A UV filter protects your delicate and expensive camera lens from dust, fingerprint, scratches, and more importantly, from physical shock and damage. However, it does sound like the functions of another filter, a 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 longpass filters that block & cut the UV wavelength range and transmit the visible spectrum, the light we see in our eyes. Discover
