B + W 49mm Wide Angle Circular Polarizer Multi Coated Thin Glass Filter

About this item

• Polarizer filters evenly increase color saturation of all colors (except black and white), creating deep, rich scenics.

• They add contrast for dramatic skies and ariel shots.

• Polarizers also eliminate glare from highly reflected surfaces like glass and water.

• Polarizers are two part lenses that rotate, allowing you to select the degree of additional saturation, contrast and glare reduction desired.

•They come in two varieties.

• Circular-for all types of cameras (required for beam splitting metering systems commonly found in auto-focus SLR's and in most current TTL Slr's; check your camera's manual).

• Linear-for rangefinders and older SLR metering systems.
