K&F Concept - 55mm Classic Slim Blue Multicoated Circular Polarizer Filter

Pro Optic Pro Digital Multi Coated Filters are renowned for their ability to reduce flare and ghosting and minimize reflection. High quality components, from optically precise elements to lightweight metal rims, ensure the performance of today's multicoated lenses. Pro Optic Professional Digital Multi Coated filters are recommended for enhancing sharp contrast and balanced color. The ProOptic Digital Essentials Filter Kit features: Ultra Violet (UV) Filter Absorbs the ultraviolet rays natural to the atmosphere which often makes outdoor photographs hazy and indistinct. The color balance remains completely unaffected. The Multi-Coated UV filter is useful for color as well as black and white photography. This essential filter shields your expensive lenses from abrasion and stray damage as a front element protector. Filter Factor of 1x (no exposure change). Circular Polarizer (CPL) Filter Reduces glare and enhances color by selectively cancelling the amount of reflected polarized lightwaves caused by a wide variety of objects, such as glass from buildings, cars and vessels, the sky and clouds, foliage, precious gems, pavement, sand, snow and water. In landscape photography, a CPL can piercehaze revealing dramatic vistas, increase tone and color vibrancy plus give the illusion of depth. By carefully rotating the rings of the filter, you can observe the cancellation effect in the viewfinder tothe degree that you desire. The filter has no effect on metallic substances as they do not reflect polarized light and little effect on flash as the light source must be polarized as well. The Filter Factor varies from 1.25x to 2x depending on the strength of effect. Neutral Density (ND2x) Filter Neutral Density filters evenly reduce the amount of light passing thru the lens without effecting color. They are ideal for situations when a narrow depth is field is needed and the lighting is too bright to allow for large apertures with your chosen shutter speed. Likewise, they allow for slower shutter speeds when you want to record objects in motion. ND filters are a must have tool for filmmakers as well. The ND Filter also lets you use high speed films in bright light, in case you haven't gone digital yet.
