Heliopan 705540 55mm Slim CIRCULAR Polarizer SHPMC Lens Filter

The darkest blue sky is achieved photographing objects at a 90 angle to the sun. In addition, polarizers enhance the color saturation of the scene by suppressing reflections from the subjects surface. Undesired reflections can largely be eliminated. The rim is calibrated to help in finding the proper setting when a through-the-lens preview is not available. Suitable for use with auto-focus cameras, cameras with through-the-lens metering and digital cameras. Model # 705540 Features: For brilliant color reproduction, best contrast and sharpness Heliopan offers the highest quality optical glass from the German Schott Group. SH-PMC broadband coatings of 8 layers per side for the highest reflection reduction (below 0.2%). Dust and moisture repellent top coating on each side for easy cleaning and longest life Slim mount does not vignette with 21mm lenses. Minimal reflections because of matte black anodized brass filter rims which will not bind when threaded in combination with other metals.
