Digitally Optimised (DG) Filters
EX DG filters benefit from Sigma's multi-layer lens coating, developed to
counteract the highly reflective characteristic of image sensors. With older
style filters, light would reflect off the image sensor, bounce off the lens and
filter elements and re-enter the image sensor, creating a ghost image. The
multi-layer coating dramatically reduces this effect. In addition to this, an
optimum, neutral colour balance is ensured, increasing the white balance
accuracy of the digital camera.
Wide Multi-Coated Circular PL
It reduces the glare and reflections from glass and water and other non-metallic
surfaces. It deepens blue skies, and saturates the colors. The Sigma circular PL
filter is designed to give best performance with AF Cameras. The Sigma wide
multi coated circular polarizing filter is very thin, so it does not cause
vignetting with wide-angle lenses. You can monitor the changes at different
angles through the viewfinder as you rotate this filter.
