Incorporating two Extraordinary Low Dispersion glass elements to reduce chromatic aberration to a minimum & ensure sharp, quality images. The Internal Focus system ensures the overall length of the lens does not change during focusing, ensuring convenient handling & ease of use. The Hyper Sonic Motor (HSM) ensures an ultra-quiet, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, & Nikon mount lenses. A 46mm filter can be inserted near the rear of the lens, & a circular polarising filter can be used in situ. ...

The Sigma 82mm 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 82mm 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. ...

Lightweight, compact & packed with features. The Sigma 85mm f 1.4 DG DN Lens is a beautiful portrait lens designed for use on full-frame mirrorless cameras. Like mirrorless systems, this lens is super-lightweight, coming in at half the weight of the original Sigma 85mm. The lens is made up of 15 elements in 11 groups, including 5 SLD & 1 Aspherical glass elements. It's wide max F1.4 aperture & 11-blade rounded diaphragm is able to produce wonderfully smooth bokeh & means that you can play with a very shallow depth-of-field to create highly impactful portraits. The focusing system that features a powerful stepping motor is capable of fast, smooth & quiet focusing which will be invaluable to professionals at weddings & other events. ...
