The high-end, hyper-telephoto zoom lens that enables any photographer with high demands to get the exact shots they want Achieves the best optical performance that embodies the concept of our Sports line. Covering all the essence. Portable,durable and of a high-standard –A Masterpiece of hyper-telephoto zoom lens. Dust- and splash-proof, zoom lock at every focus distance, water-repellent coating, compatibility with the new tele converters, new OS system with acceleration sensor, easily accessible manual over-ride switch, optimized auto focusing, telephoto shooting at 600mm, minimized chromatic aberration for higher optical performance and enhanced enjoyment with beautiful build quality. Since telephoto zoom lenses are often used under very challenging situations, this model has crystalized all the possible qualities and features to achieve the best optical and action-capture performance. While combining high portability and durability, this high-performance hyper-telephoto zoom lens from our Sports line offers outstanding rendering capabilities. Its versatility provides better flexibility for wider shooting scenes, and the high-performance definitely stimulates photographers’ artistic expression. Embodying the concept of our Sports line of lenses, this lens responds directly to photographers' needs with outstanding action-capture performance. In addition to the highest levels of optical performance and photographic expression, SIGMA’s new Sports line of lenses offers the kind of action-capture performance that precisely executes the intentions of the photographer. Uncompromising optical performance and photographic expression allow the photographer to shoot fast-moving and distant subjects, while exceptional functionality makes possible excellent shots even in the most challenging of situations. Fully customizable, it allows the photographer to create his or own specification. It is an ideal choice for photographing many different subjects; birds, wild animals, airplanes, motorsports, and even portraits. And SIGMA’s exclusive software makes the lens extremely easy to customize.   Features   Features and Functions   By incorporating excellent optical glass elements, it minimizes chromatic aberration and achieves class leading image quality. This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite and 3 SLD (Special Low Dispersion) glass elements, and compensates for color aberration at the utmost. Chromatic aberration in particular, which could be visible especially towards the telephoto end even when stopped down, is corrected by the optimized design of glass elements including FLD lenses. * FLD glass is the highest level low dispersion glass available with extremely high light transmission. This optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images.   Flare and ghosting reduction From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.   Exclusive low-dispersion glass The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain.To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.   Rounded diaphragm When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect – even at large-aperture settings.
