Specification

With its wide zoom range, this lens has a focal range equivalent to 25.5-105mm on a 35mm camera. 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. It's a compact lens ideal for everyday use, offering uncompromising optical performance, functionality, quality, and elegance.

Contemporary line can handle all sorts of photo opportunities Sigma is organising 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. The SIGMA 17-70mm F2.8-4 DC MACRO OS HSM is the first product from the Contemporary line. Featuring a wide zoom range, the lens has a focal range equivalent to 25.5-105mm on a 35mm camera.

Excellent for macro photography This lens' minimum focusing distance is 22cm and the maximum magnification ratio is 1:2.8. At 70mm, the working distance becomes 5.52cm. When it comes to telephoto, it can shoot pictures with a similar sensation to a macro lens. Also, without the need to change the lens, it enables photographers to take close up pictures of subjects such as jewellery and flowers. In order to secure a clear field of view, the design of this lens is very throughout, even down to the precise position of the engraved letters on the lens.

30% smaller than conventional models For a lens which is used used in everyday situations, the small size makes a big difference. By incorporating a smaller OS unit and optimising the structure and power distribution of optical elements, the lens barrel has now become more compact. In order to ensure high accuracy of the product, the new compound material TSC (Thermally Stable Composite), which has high affinity to metal parts, is introduced for the lens barrel. It results in better durability of the parts and smaller zoom rings and scale rings. The dimension of this lens is 30% smaller than our conventional models.

Superior image quality throughout the entire zoom range This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, 1 SLD (Special Low Dispersion) glass element and 3 aspherical glass lenses including a double sided aspherical lens. By optimizing the power alignment of the lens, both chromatic aberration of magnification and axial chromatic aberration have been corrected. From infinity to macro, it achieves superior image quality through entire zoom range. This lens offers extraordinary expressive power and is capable of surpassing the requirement of the rigorous checking process of our new MTF measuring system “A1”.

Large maximum aperture of F2.8 The aperture value is F2.8 at the wide end (17mm), and is F4 at the telephoto end (70mm). The bright viewfinder aids focusing and composition of images. 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.

Optical Stabiliser 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.

Flare and ghosting conscious design In order to achieve high rendering on this flagship lens, flare and ghosting were thoroughly measured from an early stage to establish an optical design which is resistant to strong incident light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.

Rounded diaphragm The 7 blade-rounded diaphragm creates an attractive blur to the out-of-focus areas of the image.

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

Ease of use The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the design of the lens cap and AF / MF changeover switch has been improved.

Newly developed “USB DOCK” exclusively for new product lines Based on these new lines, we have developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus. Please attach a USB Dock to your lens' mount part, just like you attach your camera to the lens. Please use the supplied USB Cable and connect to a computer which has the dedicated software “SIGMA Optimization Pro” installed. For further information on how to operate the product, please refer instruction manual of “SIGMA Optimization Pro”.
