ProMaster 55mm CIR-PL Circular Polarizing Filter

Especially useful with auto focus and auto exposure cameras.

Fits all film and digital camera lens with 55mm filter threading.

The ProMaster 55mm Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions.

The ProMaster Polarizing filter does not affect the overall color balance of a shot. Great for use with all traditional and digital cameras.

Includes protective case.
