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.
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.
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.
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.SIGMA lens technology
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.
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.
Dust-proof and splash-proof construction
It is dust and splash-proof, and designed for higher durability. It is able to meet the demands that professional photographers would require in challenging shooting conditions, such as in the rain.
Water and oil-repellent coating ensures pleasant photography experience
Forefront and rear lenses incorporate a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
TSC (Thermally Stable Composite)
Conventionally it is considered essential to leverage the qualities of metal and polycarbonate in camera and lens layout design. A first for the industry, the barrel of the new series of SIGMA lenses features a new TSC (Thermally Stable Composite)* that offers minimal thermal shrinkage combined with exceptional hardness. It also offers 25% greater elasticity than polycarbonate. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens.
*TSC (Thermally Stable Composite) offers thermal expansion characteristics similar to those of aluminum. Parts made with TSC deform less, making possible lens construction of extremely high precision. As compared to polycarbonate containing 20% glass, a commonly used material, TSC offers approximately 70% higher elasticity. As compared to polycarbonate containing 30% glass, it offers 25% higher elasticity. (Comparison is between SIGMA-produced components.)
Intelligent OS featuring updated algorithm
The OS (Optical Stabilizer) function features an acceleration sensor to ensure even higher precision. Two OS modes are available: Mode 1 for general photography and Mode 2 for motor sports and other applications requiring panning. In Mode 2, the acceleration sensor teams up with the Intelligent OS and its updated stabilization algorithm to deliver effective stabilization while you move the camera horizontally, vertically, or diagonally—regardless of the position of the lens. This feature helps ensure effective panning and outstanding capture of moving subjects.
*This lens cannot be used on film SLR cameras with the exception of the Nikon F6, Canon EOS-1V.
Quieter and Faster “Optimized AF”
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF. With the further enhanced AF algorithm compared to previous models, continuous AF (AF-C) improves the focusing efficiency by approximately 5%.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens
Newly designed tripod socket enables desirable fixing
The tripod socket is newly designed since hyper-telephoto zoom lenses like this one which has 600mm tele end often need a monopod or tripod for shooting. While ensuring that the tripod socket is large and stable, it’s possible to click the position at every 90゜to make the change of shooting position from and to vertical and horizontal much easier. By attaching the supplied strap, the lens can be carried safely without putting unnecessary pressure on the mount of the camera.
* Tripod socket cannot be detached from the lens
Manual override incorporated to make two full-time manual modes switchable
In addition to AF/MF, MO (Manual Override) is incorporated as one of the options of the focus mode switch. By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF. With AF position, standard full-time manual focus is available. Using the optional SIGMA USB DOCK, it is possible to adjust the MO position’s sensitivity to switch to manual focus.
Zoom lock switch can be set at any focal length
The new zoom lock switch enables the zoom ring to be locked at any focal length. It can be fixed at the photographer’s desirable focal length, which allows stable shooting whether the lens is positioned upward or downward. It also helps during long exposure photography
Offering excellent usability as a straight zoom
This lens is optimized to allow the zoom ring to expand/contract smoothly in order to immediately adopt without adjusting the holding position, even to a sudden change in angle-of-view. The lens front is designed to ensure easy handling in such situations.
A comfort model of Contemporary line incorporating the main specifications of 150-600mm F 5-6.3 DG OS HSM | Sports is also available. Click to learn more.
Newly designed Tele Converters that enables AF to be effective up to F8
Tele Converters that are newly designed to match the new lens line-ups (optional, planned to be released in 2014) can be attached. The addition of SIGMA’s TELE CONVERTER TC-1401 or TELE CONVERTER TC-2001 produces a MF 210-840mm F7-9 hyper-telephoto zoom lens or a MF 300-1200mm F10-12.6 hyper-telephoto zoom lens respectively. In addition, when SIGMA TELE CONVERTER TC-1401 is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF.
*When shooting subjects with low contrast or luminosity value, focus may not be spot on the subject.
Exclusive low-dispersion glass incorporation
SIGMA TELE CONVERTER TC-1401 incorporates 1 SLD and SIGMA TELE CONVERTER TC-2001 incorporates 2 SLD glass elements, which ensures high-performance image quality.About Tele Converter
46-megapixel Foveon direct image sensor
The 46 effective megapixel (4,800 × 3,200 × 3 layers) and 44 recording megapixel (4,704 × 3,136 × 3 layers) 23.5 × 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moiré is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46-megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.More about the sensor
