Digitally Optimised (DG) Filters
Sigma’s EX DG filters benefit from our 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.
Multi-coated
UV Filter
This filter perfectly eliminates the harmful effect of ultraviolet light.
The multi-coated UV filter can be used with both colour and black-and-white
film and digital sensors. This is the most suitable filter for protective
use and general photography.
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.
Circular Polarizing Filter
This type of Polarizing filter has a large diameter and it also deepens
the intensity of blue skies, eliminates glare. It not only reduces the
reflection from non-metallic surfaces, but also increases colour saturation
perfectly.

What
Digital Camera - April 2006 |

Photography
Monthly - May 2007 ‘This very thin filter works well, with the ribbed rotating collar giving good purchase and a delightfully smooth action. It delivers a fine optical performance and the multi-coating certainly helps reduce flare.’ |
