Specification :
The Marumi FS PLUS UV is a new basic model UV control filter with a water-repellent function adhered, well suited to whom easy-maintenance is a higher priority.
A UV(Haze) filter allows you to;
- prevents or attenuates a specific range of ultraviolet lights that pass into a camera to restrain haze and glare
- maintain image contrast and sharpness while reducing the 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, or, more importantly, from physical shock and damage.
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 by 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 transmit the visual spectrum that the light we see in our eyes.
