The very latest optical technology has been incorporated in the production of the new Macro 50mm F2.8 EX DG. This ideal standard lens sets the benchmark for digital SLR cameras. This standard macro lens enables you to enjoy the communication with subject. When viewing through the cameras finder, you are able to move your subject, & make precise adjustment. It has a close working distance & it is very convenient for taking close-up pictures of a fossil, or other inanimate things for example. The new advanced lens design corrects various aberrations. This macro lens is specially coated to get the best colour balance whilst cutting down ghost caused by reflections from the digital image sensor. This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras. ...

The Sigma 52mm EX DG Circular Polarising Filter reduces the glare & reflections from glass & water & other non-metallic surfaces. It deepens blue skies, & saturates the colours. The Sigma circular PL filter is designed to give best performance with AF Cameras. The Sigma wide multi coated circular polarising 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. ...

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. Suitable for protective use & general photography. ...

The Sigma 52mm Lens Cap is a spare or replacement Sigma lens cap for 52mm filter thread lenses. ...

Attachment ring to allow the Sigma EM-140 Macro Ring Flash to be fitted to lenses with a 52mm filter thread. ...

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. ...

The Sigma 52mm Protector WR filter is designed 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. 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 only filter that darkens the sky in colour photography without affecting colour balance; polarising filters cut out the glare from water & non-metallic surfaces & allow shooting through glass windows. Sigma's Multi-Coated circular polarising filters are designed for use with AF SLR & MF SLR cameras. The multi-layer coating reduces reflection. ...
