Tiffen 40.5mm Circular Polarizing Lens Filter and Lens Cleaning Brush Bundle

The circular polarizing filter absorbsrays of sunlight. Polarizers are two part lenses that rotate, allowing you to select the degree of additional saturation, contrast and glare reduction desired. They eliminate the whitish glare from highly reflected surfaces like glass and water. A Circular Polarizer has the same effect as a polarizer filter and is used on cameras with beam splitting metering systems commonly found on auto focus SLRs (for most 35mm auto-focus cameras see your camera manual). The Standard Circular Polarizer filter blocks 1.5 stops of light and is one of those must have filters.
