£1199The full-frame mid-telephoto 135mm F1.8 is the longest prime lens in SIGMA’s Art line-up, delivering exceptional optical quality, a fast aperture and a solid build. The lens is ideal for portraits, weddings, events and telephoto landscapes. Its spectacular bokeh makes it a must-own optic for photographers who want to separate their subject from the background with strong perspective compression.
The lens features two SLD elements and two FLD elements as part of its advanced optical design. These help to minimise chromatic aberration, which often appears in out of focus areas and around areas of very high contrast, such as tree branches against a bright sky. The end result is ultra-high resolution and clarity throughout the image, even wide-open.
The lens has an HSM motor for fast and accurate focusing, and a dust- and splash-proof construction that helps to keep it safe from the elements when being used outdoors.
The superb build quality of the 135mm F1.8 DG HSM is exactly as you’d expect from an Art-line lens, both in its intuitive ergonomics and in the quality of craftsmanship.
The lens’ outer barrel is made of a polycarbonate called Thermally Stable Composite (TSC), which is not only strong and light, but has a similar thermal expansion rate to aluminium. This ensures that the interior aluminium parts and the exterior TSC parts behave in the same way as temperatures change.
The focus ring is rubberised for easier operation, and focusing is internal, meaning the lens never changes length.
To reduce flare and ghosting in bright sunlight, and to help protect the front element from damage if dropped, the lens has a robust lens hood.
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

The 135mm F1.8 DG HSM | Art for DSLRs boasts outstanding optical quality, with excellent rendering of detail right into the corners even wide open at F1.8.
The lens has an advanced optical design made up of 13 elements in 10 groups, including 2 SLD elements and 2 FLD elements. This ensures razor-sharp results with very minimal chromatic aberration, flare, distortion and vignetting.
An advanced Super Multi-Layer Coating helps to reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks.
With its F1.8 aperture and relatively long focal length, especially for a prime lens, the 135mm can produce a very shallow depth-of-field. In fact, the depth-of-field is narrower than the 105mm F1.4 at the same subject distance. Also the background blur is magnified, giving the appearance of an even greater fall-off of sharpness. In this image the background is blurred even with the subject some distance from the camera.
The 105mm F1.4 DG HSM and the 135mm F1.8 DG HSM are the two longest lenses in the DSLR Art range. The 105mm has the slightest wider aperture of F1.4 to the 135mm’s F1.8, and is about 500g lighter. Both lenses offer exceptional image and build quality, and are both well known for their beautiful bokeh. Owing to its extra weight, the 105mm comes with a tripod collar.

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.
If you want to see how a particular SIGMA lens or camera performs, why not test drive it with our SIGMA Select hire service. Available for selected SIGMA lenses, short-term loans are free of charge (including shipping), with a small fee if you want to test it for longer. Refundable deposit required.

A special coating applied to the front element to help repel water and oil.
This suppresses flare and ghosting by minimising reflections within the lens, ensuring punchy, high-contrast results. All lenses in the current Sigma range feature this technology.
Internal focus or an inner focus system means the lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel. This helps keep the centre of gravity of the lens more constant when changing focus.
Sigma’s Hypersonic Motor (HSM) uses ultrasonic waves to drive the autofocus mechanism. It is extremely quiet, fast and accurate, so is well suited to a wide range of photo and video applications.
The lens has an image circle large enough to be used on a full-frame camera. It can also be used on cameras with a smaller ‘crop’ sensor, provided the mount is compatible.
The lens has a filter thread around the front element onto which filters and filter holders can be attached.
The mount is the part of the lens that attaches to the camera body. A coated brass mount is used for strength, and is surrounded by a rubber seal to keep out dust and moisture.
This switch toggles between autofocus and manual focus.
The diaphragm is constructed of nine rounded blades for a circular aperture opening and round out-of-focus highlights.
