A high-performance zoom lens offering exceptional image quality, compactness and performance

Featuring SIGMA's latest technologies,
combining optimized optical performance
with superior utility.

Best-in-class image quality and compactness let you shoot in the widest possible range of situations.
It's the high-level lens you trust for both everyday use and exceptional circumstances.

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.

Features

True macro photography
- anytime, anywhere

With a minimum focusing distance of 22cm
and a maximum magnification ratio of 1:2.8,
this lens rivals macro lenses in results.

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.

HSM (Hyper Sonic Motor)

HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance.

Optical Stabilizer

SIGMA’s own unique OS (Optical Stabilizer) function is incorporated. It offers superior stabilization, which makes it possible to compensate for camera shake even in macro range photography where a small blur can be easily identified.

Note:
・The closer the lens is to the object, the less effective the OS function is.
・The OS function is not available with Pentax mount.

30% more compact than previous lenses of its type

Completely rethinking the materials and structural layout
to set a new benchmark for slim lens construction.

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.

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.

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.

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.

Superior image quality throughout
the entire zoom range

From infinity to macro distances,
this lens delivers superior image quality throughout
the zoom range.

To offer top image quality throughout the zoom range, the lens features 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, as well as a SLD (Special Low Dispersion) glass, which helps minimize chromatic aberration. The result is superior image quality from infinity to macro distances. Double aspheric lenses produced by precision glass molding and a newly designed cam with a highly complex structure help minimize astigmatism and other forms of aberration and realize top image quality. The bright finder lets photographers compose their images easily. In combination, these features make possible an attractive background bokeh effect at a high shutter speed while minimizing blurring of the subject.

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.

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.
