A standard zoom that won't weigh you down /

Combining outstanding optical performance, an F2.8 constant aperture and a light and compact body, the 28-70mm F2.8 is the ultimate portable standard zoom for mirrorless cameras. With a similar optical design to the 24-70mm F2.8 DG DN | Art, but significantly smaller and lighter at only 56% of its weight, the lens is ideal for photographers and videographers who need a high performance, all-in-one standard zoom that isn’t going to weigh them down. At the point of release the 28-70mm was smallest and lightest standard zoom with a constant F2.8 aperture on the market for full-frame mirrorless cameras.

The lens is highly versatile and is perfect for a wide range of photographic applications including landscapes, portraits, weddings, street, close-ups and architecture. It’s also ideal for video and light enough to be used on a small electronic gimbal. The optical design includes two FLD, two SLD and three aspherical elements for staggering sharpness across the frame with very little in the way of unwanted aberrations.

True to the core concept of the Contemporary line, the 28-70mm F2.8 DG DN delivers the perfect balance of performance and portability.

The 28-70mm is a real workhorse lens that is versatile enough to be used for almost any type of photography.

Features and build /

The outer barrel of the 28-70mm is constructed using a polymer called Thermally Stable Composite (TSC). This has a similar thermal expansion rate to aluminium, meaning that the metal interior of the lens and the TSC exterior behave in the same way as temperatures change. TSC is also light and strong, and has a sleek finish for a premium look.

The lens has an internal focus mechanism, so the lens always remains the same length when the subject distance changes. This makes it well suited to gimbal use due to a relatively constant centre of gravity, and it also means the end of the lens doesn’t rotate when focusing – important when using filters.

The lens has a stepping motor that delivers smooth, fast and accurate AF for both stills and video. It has been designed with lighter glass elements in the focus lens group, which ensures responsive autofocus that is fully compatible with all the latest AF camera technology.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

IMAGE QUALITY IS EXCEPTIONAL AT ALL APERTURES AND FOCAL LENGTHS, WITH SUPERB COLOUR RENDITION.

Razor-sharp optics /

Despite weighing only 450g, the 28-70mm F2.8 DG DN | C delivers outstanding optical quality even on very high-resolution sensors. Optical performance is maintained across the whole frame, meaning fine detail is rendered perfectly right into the corners.

The lens has an advanced optical design made up of 16 elements in 11 groups, including 4 aspherical elements and 5 FLD elements. These ensure razor-sharp results and work with in-camera digital corrections to eliminate chromatic aberration, flare, distortion and vignetting.

The lens has advanced optical coatings which reduce flare and ghosting when working in bright direct sunlight – important on an ultra-wide-angle lens.

Superb low-light performance /

The 28-70mm has constant, fast F2.8 aperture, which makes it a very useful lens for working hand-held in darker environments such as interiors, weddings and night scenes.

Perfect for portraits /

The fast constant aperture creates a shallow depth-of-field that helps the subject to stand out from the background, making the lens perfect for portraits. The wider end of the focal range is best for environmental shots, with the tighter end perfect for a classic head-and-shoulders composition.

Compact and lightweight /

The 28-70mm is one of two full-frame mirrorless standard zooms in the Sigma range. The other is the 24-70mm F2.8, which sits in the Art line of optics. The 24-70mm zooms out 4mm wider, has an AFL button, a lockable hood, and a slightly more premium build, although it’s both heavier and longer. Both lenses have the same maximum aperture and comparable image quality.

SIGMA Landscape Pro twin lens kit /

If you’re tempted by the 28-70mm F2.8, why not consider the Landscape Pro twin lens full-frame zoom kit, which also comes with the 16-28mm F2.8 and two WR protector filters. Covering ultra-wide to short-telephoto with an F2.8 aperture, these portable, versatile and optically excellent lenses are an absolute staple for landscape photographers who like to travel light.

The kit costs £1429, saving you £244 off SRP.

Made in Aizu /

All Sigma cameras and lenses are designed, manufactured and assembled at our sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.

Sigma chose Aizu as its main production base in the early 1970s. Situated at the base of Mount Bandai in the Fukushima Prefecture, about four hours’ drive north of Tokyo, Aizu has an abundance of very clean water from mountain streams, which is essential for grinding and polishing lenses. Sigma’s founder, Michihiro Yamaki, was also drawn to this area for its workforce, who have a reputation for their craftsmanship, work ethic and attention to detail. Mr Yamaki’s son, Kazuto Yamaki, now the owner and CEO of SIGMA Corporation, has the same unwavering commitment to keeping production in Japan.

Today Sigma’s factory is more than 50,000 square feet in size, and packed full of some of the most advanced optical manufacturing technology in existence. So when you buy a Sigma camera or lens you can be sure that virtually every single component part has been manufactured and assembled by SIGMA, in Japan, with the greatest level of care and attention. We hope you enjoy using our products.
