Combat the effects of bright or flat illumination & add new depth to your photographs with the Sigma AFC-950 58 mm Circular Polarising Filter. Suitable for film & digital Built to fit standard 58 mm lens threads, the A-FC950 Polarising Filter features a high-quality optical design for both film & digital cameras. Its versatile light-filtering performance works wonders to reduce glare & reflections from glass & water, effectively diminishing or eradicating areas of blown-out highlights, loss of contrast & diminished image information. Especially useful in bright light or low contrast settings, this filter results in deeper blues, richer colours & more defined details in areas previously obscured by light. Now your outdoor images will attain richer colour saturation levels with reduced glare & reflections from non-metallic surfaces for even better photography. Benefits of a new design The AF-C95-0 58 mm Polarising Filter is characterised by a multi-layer lens coating, created to offset the extreme reflections often generated within image sensors. In older filters, light would reflect off the sensor, bounce off the lens & filter elements, & then re-enter the sensor, resulting in a ghost image. The multi-layer coating & digitally-optimised design of this filter drastically decreases this effect, ensuring an excellent, neutral colour balance & benefitting the white balance accuracy of the digital camera. This 58 mm circular Sigma Polarising Filter has been designed with a wide diameter & an ultra-slim screw-in mount that allows it to be used with wide lenses for true versatility. Take the shots youve always wanted to with the Sigma AFC-950 58 mm Circular Polarising Filter first time around.
