  • Hyper Sonic AF Motor
  • Optical Stabilizer
  • Macro Capabilities
  • Compact and Lightweight TSC Construction
  • FLD, SLD, and Aspherical Lens Elements
  • Super Multi-Layer Coating

Best-in-class image quality and compactness let you shoot in the widest possible range of situations.

With its wide zoom range, the lens has a focal range equivalent to 25.5-105mm on a 35mm lens. Thanks to Sigma's latest technologies, it's exceptionally lightweight and 30% more compact by volume than previous lenses of its type. Its low F-number equips photographers to shoot subjects at extremely close range, making this the perfect lens for travel, family photos, artistic compositions, and many other uses. A complement to uncompromising optical performance, functionality, quality, and elegance, the compact size of the lens makes it ideal for everyday use. It is highly beneficial to photographers that the lens they use the most is one of the best in quality they have.

The full realization of the Contemporary product concept, combines lightweight, compact construction with best-in-class image quality and performance.

Sigma is organizing all its interchangeable lenses into three product lines; Contemporary, Art and Sports. Featuring the very latest technology, and combining optical performance with compactness, the Contemporary line covers a wide range of needs. Incorporating the very latest technology in these lenses, Sigma has solved the difficult problem of keeping size and weight low without compromising optical performance.

Mimimum Focusing of 22cm

Being able to shoot close to the subject is a crucial element in photography. This lens features a minimum focusing distance of 22cm and a maximum magnification ratio of 1:2.8, producing results that rival those of macro lenses. At 70mm, its working distance is 5.52cm. When used as a telephoto lens, it's so close to a dedicated macro lens in performance the lens hood seems to touch the subject. Since its range extends from the 35mm equivalent of 25.5mm to 105mm, the lens is perfect for shooting close-ups of fashion accessories, cuisine, flower arrangements and much more. Uncompromising in every aspect of lens design, Sigma has even chosen not to place the product name on the front of the lens to prevent reflection of the letters during close-up photography.

Optical Stabilizer

Sigma's own unique OS (Optical Stabilizer) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate for camera shake even in macro range photography where a small blur can be easily identified.

30% more compact the previous version

To create a high-performance, compact lens that's ideal for use in the widest possible range of situations, Sigma slenderized the lens barrel by reducing the size of the image stabilization OS unit and optimizing the lens power distribution and structural layout. The barrel features TSC (Thermally Stable Composite), which offers a high degree of compatibility with metal parts. Since its thermal shrinkage is low, TSC matches well with metal parts, further contributing to the high-precision construction of the lens. TSC also makes possible slimmer forms for parts like the zoom ring and scaling ring. These advances make possible a combination of best-in-class optical performance and a size 30% more compact by volume than previous lenses of its type.

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.)

A refined, integrated design made with the photographer in mind.

All lenses in Sigma's new Contemporary line come with a hood with a high-quality rubberized connector and feature a newly designed lens cap and AF/MF switch, and are designed for intuitive use and superior functionality. Inside, HSM (hypersonic motor) delivers high AF speed and extremely quiet performance. An enhanced algorithm offers even smoother automatic focusing. The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Specially designed cam for smooth zooming

The specially designed cam makes possible smooth and rhythmical zooming, allowing photographers to find the right focus instantly and shoot with perfect timing.

F2.8 at the wide-angle end (17mm) and F4 at the telephoto (70mm) end of the range

The fast apertures also offer useful functions such as fast shutter speeds to prevent an object from being blurred and ensuring a smooth bokeh in the background.

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.
