The Sigma 46mm Plain Filter is designed to protect the large telephoto Sigma lenses using the rear drop in system. ...

The Sigma 46mm Protector filter is developed to protect the lens surface from dirt & dust as well as scratches. It is an ideal filter for regular use as it is completely colourless so does not affect colour reproduction. ...

Sigma's weather-resistant (WR) circular polariser (CP) filters remove reflections on the water's surface & glass windows, & increases the contrast in landscape photography. This effect is often used to increase the contrast & saturation in blue skies & white clouds. With excellent water & oil repellent functions, the filter surface repels water drops & provides resistance to fingerprints. Even if they appear on the surface they can be easily removed. ...

Sigma's weather-resistant (WR) ultra-violet (UV) filters prevent the bluish tone that generates when the weather is fine, by absorbing ultraviolet rays. It is effective in most situations, such as landscape, portrait & general photography on a sunny day. It is also an ideal filter for regular use as it is completely colourless so does not affect colour reproduction. With excellent water & oil repellent functions, the filter surface repels water drops & provides resistance to fingerprints. Even if they appear on the surface they can be easily removed. ...

The Sigma 49mm EX DG Circular Polarising Filter reduces the glare & reflections from glass & water & other non-metallic surfaces. It deepens blue skies, & saturates the colours. The circular PL filter is designed to give best performance with AF Cameras. The wide multi coated circular polarising filter (49mm to 82mm) 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. ...

Sigma’s EX DG UV filters benefit from a 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 & filter elements & 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. The Multi-Coated DG UV filter perfectly eliminates the harmful effect of ultraviolet light. The multi-coated UV filter can be used with both colour & black-&-white film & digital sensors. This is the most suitable filter for protective use & general photography. ...
