The Sigma Corporation is pleased to announce the launch of the new
SIGMA EX DG range of filters which is optimized for digital SLRs. The new
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 eliminates unnecessary internal
reflections. The Sigma EX DG Circular Polarizing (CP) filters which eliminate
reflections from subjects such as glass and water and deepen the intensity of
blue skies. These Cir-Pol filters, with the exception of the 86mm, 95mm and
105mm, is encased within an 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.
