Counteract the effects of bright or flat lighting & add new intensity to your photographs with the 72 mm Sigma AFF950 Circular Polarising Filter. Use with film or digital Made to fit standard 72 mm lens threads, the AFF950 Polarising Filter sports a high-quality optical design thats suitable for both film & digital cameras. Its all-round light-filtering performance works brilliantly to diminish glare & reflections from glass & water, successfully cutting down or preventing the occurrence of blown-out highlight areas, decreased contrast & loss of image information. Particularly useful in bright light or low-contrast settings, this filter gives you deeper blues, more vibrant colours & more distinct details in areas previously concealed by light. Now your outdoor images will achieve higher colour saturation with reduced glare & reflections from non-metallic surfaces for enhanced photography. New filter design for wider usability The AFF950 Polarising Filter is distinguished by a multi-layer lens coating, fashioned to counterbalance the excessive reflections often generated within image sensors. In older filters, light would reflect off the sensor, bounce off the lens & filter elements, & re-enter the sensor, causing a ghost image. The multi-layer coating & digitally-optimised design of this filter radically reduces this effect, ensuring an outstanding, neutral colour balance & improving the white balance precision of the digital camera. This 72 mm circular Sigma Polarising Filter has been made with a wide diameter & an ultra-slim screw-in mount that allows for use with wide lenses for true adaptability.
