This Contemporary Line lens features the very latest technology and combines optical performance with compactness – Sigma has solved the difficult problem of keeping the size and weight low without compromising optical performance.

The dimensions of this new Contemporary line lens are 30% smaller than previous conventional model – by incorporating a smaller OS unit and optimizing the structure and power distribution of optical elements, the lens barrel has become more compact – the new TSC (Thermally Stable Composite) compound material which has a high affinity to metal parts, is introduced in the lens barrel, resulting in better durability of the parts and smaller zoom rings and scale rings.

This lens incorporate 2 FLD (“F” Dispersion) glass elements which have the performance equal to fluorite glass, 1 SLD (Special Low Dispersion) glass element and 3 aspherical glass lenses, including double sided aspherical lens. By optimizing the power alignment of the lens, both chromatic aberration of magnification and axial chromatic aberration have been corrected to ensure excellent image quality throughout the entire zoom range.

Another feature of this new Contemporary lens is the capability of working with the new USB Dock (optional) and special software (Sigma Optimization Pro) to update the lens firmware and adjust parameters such as focus.

The incorporation of Sigma’s Hyper Sonic Motor (HSM) provides quiet, high speed and accurate auto-focusing. Inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the supplied lens hood and circular polarizing filters.

Each lens is tested using Sigma own proprietary “A1” MTF quality control measuring system – even previously undetectable high-frequency details are now within the scope of this quality control inspection.

Sigma’s super multi-layer coating minimizes flare and ghosting – a common problem for digital cameras.
