Circular Polarising
Filter - 52 Mm
£29.98
Improve the colour & contrast in your photos with the Sigma AFA-950 52 mm Circular Polarising Filter. Optimised for digital & film cameras Benefitting from Sigmas multi-layer lens coating, this EX DG polarising filter works brilliantly to counter the high reflectivity of image sensors. In the case of older-style filters, light would bounce off the sensor, reflect off the lens & filter elements & then re-enter the sensor, which creates an unsightly ghost image. Optimised for digital photography (as well as film), multi-layer coating effectively goes to work to eliminate this effect, ensuring an optimum, neutral colour range & better white balance accuracy. This goes a long way to cutting down the glare & reflections commonly experienced when photographing glass & water. Versatile filter application The Sigma AFA95-0 52 mm Polarising Filter fits most lenses with a standard 52 mm thread, making it a wonderfully versatile accessory. It also offers an ultra-slim screw-in mount that means that you can use it with wider lenses, avoiding annoying vignetting in the process. As well as eradicating light-related visual anomalies such as glare, this excellent filter also deepens the intensity of blue in skies & water. As reflections from non-metallic surfaces are diminished, the filter also perfectly increases colour saturation, giving your images much greater dynamic range both tonally & in terms of hue reproduction. Multi-coated & benefitting from a digitally-optimised design, the Sigma AFA-950 52 mm Circular Polarising Filter is a simple yet practical choice to help you achieve better-looking photos. ...
