Latest technology for high optical performance and compactness High performance line corresponding with various photography situations

SIGMA is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Among the three, the Contemporary line is a high performance line which incorporates the very latest technology making it possible to accommodate both high optical performance and compactness for use in various photography situations. SIGMA has solved the difficult problem of keeping the size and weight down without compromising optical performance and function with the latest technology.

Excellent optical performance that satisfies experienced users

This lens incorporates 4 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite plus 1 SLD (Special Low Dispersion) glass element. It enables this lens to minimize the chromatic aberration, especially toward the telephoto end, and provide clear image quality with high color fidelity.

*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.

 

Accumulated lens technology leads to superior image quality

The most appropriate optical glass elements are selected to optimize all focal lengths of the lens. From wide angle to telephoto and macro, it offers superior image quality throughout the entire zoom range. It compensate for the distortion very well, especially at wide-end, and carries extraordinary expressive capability from the center to the corners.

Lens Construction

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 7-blade diaphragm helps produce an attractive bokeh effect - even at large-aperture settings.

Newly developed OS system for better compensation

By reviewing the system construction and the algorithm of firmware, approximately 3.5 steps higher compensation has been achieved. 
* Based on CIPA's guideline. Measuring at telephoto end, when it is attached to the camera with APS-C image sensor.

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.)

Newly Developed Hyper Sonic Motor

For comfortable and smooth use with the high zoom ratio, 16.6 times, it incorporates a bigger HSM (Hyper Sonic Motor) which is newly developed for this lens. It is powerful enough to ensure high speed and quiet AF.

 

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.

DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having image sensors larger than APS-C size or on 35mm or APS film cameras, as vignetting will occur. The angle of view varies depending on which camera the lens is mounted on. To find the 35mm camera-equivalent focal length, multiply the DC lens focal length by the crop factor (digital multiplier) of 1.5, 1.6, or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.  Sony and Pentax mounts are not incorporated with OS function. AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.
