Manufacturer's Description The Sigma DG filters benefit from super multi-layer lens coatings, developed to counteract the highly reflective characteristics of digital image sensors, reducing both flare and ghosting Black rimmed glass eliminates unnecessary internal reflections Circular Polarising Filters are regarded as the most versatile fiilters available, they work by blocking out polarised light Polarising filters offer several key benefits; darkening of blue skies without affecting colour balance, cutting out glare from non-metalic surfaces and reducing reflections from water , glass and other surfaces Sigma Circular Polarising filters are designed to work with wide angle lenses and therefore use ultra thin filter rings to reduce vignetting Sigma DG filters deliver high performance on both digital and film SLR cameras
