Counteract the effects of bright or flat lighting & add new intensity to your photographs with the 72 mm Sigma AFF950 Circular Polarising Filter. Use with film or digital Made to fit standard 72 mm lens threads, the AFF950 Polarising Filter sports a high-quality optical design thats suitable for both film & digital cameras. Its all-round light-filtering performance works brilliantly to diminish glare & reflections from glass & water, successfully cutting down or preventing the occurrence of blown-out highlight areas, decreased contrast & loss of image information. Particularly useful in bright light or low-contrast settings, this filter gives you deeper blues, more vibrant colours & more distinct details in areas previously concealed by light. Now your outdoor images will achieve higher colour saturation with reduced glare & reflections from non-metallic surfaces for enhanced photography. New filter design for wider usability The AFF950 Polarising Filter is distinguished by a multi-layer lens coating, fashioned to counterbalance the excessive reflections often generated within image sensors. In older filters, light would reflect off the sensor, bounce off the lens & filter elements, & re-enter the sensor, causing a ghost image. The multi-layer coating & digitally-optimised design of this filter radically reduces this effect, ensuring an outstanding, neutral colour balance & improving the white balance precision of the digital camera. This 72 mm circular Sigma Polarising Filter has been made with a wide diameter & an ultra-slim screw-in mount that allows for use with wide lenses for true adaptability.

Fit the Sigma AFG-940 Multi-Coated 77 mm UV Filter to the front of your lens for better colours in your photos, & protection to boot. Digitally optimised UV filter Enhanced by Sigmas EX DG multi-layer lens coating, this high-grade UV filter helps to cancel out the extreme reflective characteristics of imaging sensors. In previous filter models, the image sensor would reflect light off the lens & filter elements, before re-admitting the same light, causing abhorrent ghosting in photographs. The multi-layer coating on this Sigma 77 mm UV Filter filter significantly cuts down this effect also ensuring a precise, neutral colour balance for greater white balance accuracy in digital cameras. Improved colour & image definition The A-FG940 77 mm Multi-Coated UV Filter perfectly eliminates the destructive effects of ultraviolet light that can affect sensors & images alike. It can be used with both colour & black-&-white film & digital photographic sensors, providing excellent contrast & superior colour saturation. In addition, it protects the front lens element from dust & other damage, making ti physically as well as optically practical.A great choice for general photography as well as lens preservation, the Sigma AFG-940 Multi-Coated 77 mm UV Filter is a logical choice for expanding your camera kit. ...

The Sigma 3.5cm 1.4 DG HSM is a state of the art lens designed for full frame cameras but can also be used with APS-C sensors as well. The first addition to the Art category in Sigma's Global Vision, the 3.5cm 1.4 DG HSM

Includes:: new features based around a unique lens concept & design. The 3.5cm is a staple focal length in the world of photography, & paired with Sigma technology, this lens can take artistic expression to the next level. The lens is equipped with technology including a Hyper Sonic Motor (HSM), floating internal focusing system, SLD & FLD Glass elements. The HSM ensures quiet, high seed, accurate autofocusing while the floating focusing system allows for superior optical performance with subjects at a closer shooting distance. The SLD glass elements along with the FLD glass elements, which are equal to fluorite, help correct both axial & chromatic aberration. The large 1.4 aperture make it ideal in low light & the lens is compatible with the Sigma USB (Universal Serial Bus) dock & Optimization Pro software to adjust & fine tune focusing parameters.
