£0This versatile standard zoom for full-frame DSLR cameras is ideal for a wide range of photographic applications, from landscapes and portraits to street and travel photography. The lens features a constant maximum aperture of F4 throughout the zoom range, which allows for consistent exposure settings and a shallow depth-of-field. The lens also includes Optical Stabilization (OS) technology to minimize the effects of camera shake, allowing for sharp and clear images even in low-light situations.
The lens has an advanced optical design that comprises 19 elements in 14 groups, with three aspherical elements and two SLD (Special Low Dispersion) elements to correct for chromatic aberrations and distortion. The lens also includes a Super Multi-Layer Coating to minimise lens flare and ghosting, ensuring accurate and high-contrast image rendering.
The exceptional build quality of the 24-105mm F4 DG OS HSM is exactly as 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 a consistent way as temperatures change.
The focus and zoom rings has sharply-ribbed rubberised covers for easier operation, and the action on both is very smooth for more precise control.Â
To reduce flare and ghosting in bright sun, and to help protect the front element from damage if dropped, the lens has a robust, removable petal-type 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.
TSC construction
Made from a strong and light polycarbonate that behaves in a similar way to aluminium.
Focus ring
Rubberised for precise manual focusing.
Zoom ring
A large, rubberised ring with a smooth action.
Petal-type lens hood
Cuts down on flare while limiting vignetting.
Focus Mode switch
For changing between AF and MF.
Optical Stabilizer
Helps reduce camera shake in lower light conditions.
A range of controls on the lens include an AF/MF switch for toggling between auto and manual focus.Â
The lens has an Optical Stabilizer switch that helps to reduce camera shake when shooting in low light conditions. This provides a four-stop advantage, allowing photographers to achieve blur-free hand-held images at approximately 1/8 sec.
A powerful HSM motor ensures fast, accurate and quiet AF and excellent AF tracking capability.
The SIGMA 24-105mm produces images with outstanding optical quality, with excellent rendering of detail across the whole frame even wide open at F4.
The lens has an advanced optical design made up of 19 elements in 14 groups, including 3 aspherical elements, 2 SLD elements and 2 FLD elements. This ensures razor-sharp results and helps 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 excellent colour saturation and strong blacks.
Owing to its constant F4 aperture and Optical Stabilizer function, the 24-105mm is a cable low-light lens, so can be used in darker environments without the need for a tripod. The OS offers around a 4-stop advantage, making it possible to shoot hand-held with around 16 times less light than a similar lens without OS.
There are two standard zooms for DSLRs in the Sigma range: the 24-70mm F2.8 and the 24-105mm F4. Both have an Optical Stabilizer function and are almost identical in length. The 24-105mm has a larger zoom range, but with a narrower maximum aperture, so the most suitable lens will depend on the particular style of photography it is being used for.

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. Subject to availability.

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.
Sigma’s Optical Stabilizer function uses sensors inside the lens to detect motion, then moves specific lens elements in order to effectively minimise blur. This helps ensure shake-free images at slower shutter speeds.
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).
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.
