£729With a magnification ratio of 1:1, this true macro lens for mirrorless cameras is designed for focusing extremely close to a subject to capture it in a very high level of detail. It’s perfect for photographing natural-world objects such as insects and plants, but it can also be used for non-macro subjects such as portraits and landscapes.
The lens delivers exceptional image quality, with razor-sharp results across the whole frame at all apertures. The maximum aperture of F2.8 ensures fast shutter speeds in low-light conditions as well as a shallow depth-of-field for blurry backgrounds. A number of professional-level features are built in, including a manual aperture ring with de-click and lock switch, an AFL button, a focus limiter and a dust- and splash-resistant structure.
The 105mm F2.8 DG DN MACRO delivers the exceptional build quality you’d expect from an Art-line lens, both in the materials used and the quality of craftsmanship.Â
The exterior barrel is made of a polycarbonate called Thermally Stable Composite (TSC). Not only is this very strong and light, but it 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. This makes it ideal for use on a gimbal as the centre of gravity remains fairly constant.
Towards the rear of the barrel is an aperture ring so that aperture can be changed on the lens, and it has an Auto setting should users prefer to change aperture using the camera.
To reduce flare and ghosting in bright sun, and to help protect the front element from damage if dropped, the lens has a robust polycarbonate lens hood
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.
Precision brass mount with seal
Protects against dust and moisture.
Aperture ring
With a click/de-click switch and a lock switch.
TSC construction
Made from a strong and light polycarbonate that behaves in a similar way to aluminium.
Focus ring
A large, rubberised ring with a smooth action. Focusing is internal.
Robust lens hood
Cuts down on flare while limiting vignetting.
Focus Mode switch
For changing between AF and MF.
AFL button
Customisable depending on camera body.
Focus Limiter switch
To limit the focusing range for faster and more accurate AF.
Aperture Click switch
Clicks or de-clicks the aperture ring.
A range of controls on the lens include an AF/MF switch, and a customisable AFL button (depending on camera model).
The lens also has a click/de-click switch so that the aperture ring can be adjusted smoothly rather than in hard stops. There’s also a lock switch that keeps the aperture ring in either Auto or Manual.
A powerful stepping motor ensures fast, accurate and quiet AF and excellent AF tracking capability.
A Focus Limiter switch reduces the focusing range for faster and more accurate AF, useful if there are objects closer to the lens than the subject, such as grasses.

The 105mm macro delivers incredible image quality with superb rendering of fine detail, even when used wide-open.
Its advanced optical design is made up of 17 elements in 12 groups, including 1 SLD element, ensuring razor-sharp results and helping to eliminate chromatic aberration, flare, distortion and vignetting.
Advanced optical coatings reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks.
Often overlooked is that macro lenses are fully capable of shooting more distant subjects. With its short-telephoto focal length and F2.8 aperture, this compact prime is ideal for head-and-shoulders portraits.
With its extreme close-focusing ability, the 105mm macro is the ideal lens for picking out abstract compositions that focus on shape, texture and colour. This can produce painterly or other-worldly images that would be hard to notice with the naked eye.
SIGMA has two Art-line macro lenses in its mirrorless range. Both have an F2.8 aperture, robust build, excellent colour rendition, a focus limiter and comparable optical performance. The 105mm also has an aperture ring that can be de-clicked and locked, internal focusing, an AFL button and faster AF. The 70mm is slightly smaller and lighter. The difference in focal lengths comes down to personal preference.

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.
This describes the degree to which a lens can magnify an in-focus subject. The ratio shows the relationship between the size of the projection of a subject on the camera’s sensor (the left number) and its actual size in reality (the right number).
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.
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.
This switch, found on some Sigma telephoto lenses, allows users to limit the focusing range to either near distance or far distance. This helps speed up AF, and also ensures the camera won’t attempt to focus on an unwanted area of the frame.
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.
Found on the barrel of some Sigma lenses, the AFL button can be assigned to various functions to widen the range of operations available on the lens (available functions depend on the camera model).
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.
