ZOMEI MC HD CPL Ultra Slim 58mm Circular Polarizer Lens Filter for Canon Nikon Sony Camera
The Zomei Series double thread 18 HD Multi-Coated Circular Polarizing (PL) Filter is used Ultra Slim frame and Germany Schott Glass, which can prevent dark corners and lower reflect light, and also allows you to remove unwanted reflections from non-metallic surfaces such as water and glass. Tthe polarization rate can reach up to 99.99%, improves color saturation, definition and contrast. A polarizer is different than most filters in that it is composed of two pieces of glass, mounted independently inside a round frame so that one can be rotated relative to the other. As it is rotated, it increasingly cuts out glare and haze. With an SLR, you can actually observe this change through the viewfinder. Polarizes reduce glare from water, glass, or any non-metallic surface. You can also use a polarizer filter to darken blue skies.
1. Color and contrast enhancement Light rays which are reflected by any surface can become polarised so polarising filters are used to select which light rays enter your camera lens. CPL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer 2. Reduce dlare and reflectons Using the CPL filter, reflections and glare can be reduced significantly from non-metallic surfaces. A camera angle of 30 degrees from the reflecting surface (glass, water, etc.) is ideal for maximum effect. 3. Slim frame These excellent quality slim filters (4.68mm) will help to reduce the chance of vignetting on wide angle lenses, and this Slim Frame filter is providing both-side thread, so you can attach other accessories on it such as your lens cap. 4. With better contast This effect is often used to increase the contrast and saturation in blue skies and white clouds. Zomei's polarising filters do not affect the overall color balance of a shot.
