Sigma Circular PL 58mm EX MC

Circular PL 58mm EX MC The new Circular PL filters benefit from a super multi-layer lens coating developed to counteract the highly reflective characteristics of digital image sensors reducing both flare and ghosting. Black rimmed glass eliminate unnecessary internal reflections. Circular Polarizing (CP) filters which eliminate reflections from subject such as glass and water and deepen the intensity of blue skies. The range of CP filters, with the exception of 86mm, 95mm and 105mm, is encased within ultra-thin metal ring that does not cause vignetting with wide-angle lenses. Each of these Sigma EX DG filters is designed to accept the front cap of the lens.
