Everything required in a mid-telephoto macro lens has been achieved at highest levels
The latest optical design of the 105mm F2.8 DG DN MACRO | Art ensures exceptional sharpness at all shooting distances from extreme close-up, which is crucial in macro shooting, all the way up to infinity. In addition, its aberration correction places a particular focus on longitudinal chromatic aberration which cannot be handled by the in-camera aberration correction. The superior optical design produces clear images with both delicate rendering and free of color bleeding.
Bokeh was one of the focuses in the 105mm F2.8 DG DN MACRO | Art design, which figures largely in mid-telephoto shooting. The ample volume of peripheral light helps create beautiful bokeh circles, while natural bokeh effect in the background, as well as foreground, gives more flexibility to photographic expressions.
Furthermore, when equipped with the TC-1411 (1.4x) or TC-2011 (2.0x), Sigma’s latest models of teleconverters designed exclusively for the use with L-Mount lenses, it allows photographers to shoot macro at even higher macro magnifications while keeping the working distance.
The 105mm F2.8 DG DN MACRO | Art has achieved everything that is required of a mid-telephoto macro lens at the highest levels.
Performance data
Sigma Art line class optical and AF performance
The Sigma Art line lenses prioritize optical performance above all else in their design. This applies to the 105mm F2.8 DG DN MACRO | Art, which produces outstanding rendering performance from the center of the frame all the way up to the edges. It excellently handles comatic aberration, which often happens at the edges. On the other hand, its abilities to minimize ghosting and flare, which have been validated through rigorous testing from the early stages of its development, ensures that it performs well in backlit conditions.
On top of optimization for the latest functionalities, such as face/eye detection AF, which is something mirrorless camera systems do well, it incorporates a powerful Hyper-Sonic Motor (HSM) in its focus motor system to achieve high-precision, quiet AF operation.
All of these elements are brought to life using advanced production technology at the Aizu Factory, Sigma’s only production site, giving the 105mm F2.8 DG DN MACRO | Art the highest levels of performance worthy of the Sigma Art line.
A full range of functionalities and an excellent build quality
On its body, the 105mm F2.8 DG DN MACRO | Art features a 1 Focus Mode Switch,
2 Focus limiter setting which comes in handy during macro shooting, and the 3 AFL button*1 to which users may assign select functions. The 4 Aperture ring, which is designed to help users work intuitively, has an 5 Aperture ring click switch to turn ON or OFF the clicking sound that isn’t required by some users when shooting macro. It also comes with a 6 Aperture ring lock switch*2 for a ring lock system. Its enhanced functions allow users to customize their shooting operations in accordance with their shooting styles.
The lens also has a 7 dust and splash resistant structure* with a water- and oil-repellent coating, which is built to handle all manner of shooting conditions. The rings and switches, meanwhile, have a build quality that is superb in terms of durability, as well as how they work and how they feel.
With levels of user-friendliness, adaptability to the environment, and smoothness of operation that are designed for professional uses, the 105mm F2.8 DG DN MACRO | Art pushes the boundaries for photographers and gives them wider creative possibilities.
*1 Limited to compatible cameras. Also, the functions depend on the camera.
*2 When turned ON at the position A, the iris ring is locked at A. When turned ON at a position other than A, it is locked within the range between the maximum to minimum apertures and will not engage at the position A.
*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

MTF CHART
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.
*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

Dust and Splash Resistant Structure
This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
Water and oil repellent coating
Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
AFL button
the AFL button can be assigned with various functions widens the range of operations available on the lens.
Aperture ring lock switch
A ring lock system to prevent from unintended movement of the aperture ring during shooting.
Aperture ring click switch
Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.

Rounded diaphragm
The polygonal shape of a conventional iris dia phragm causes out-of-focus light points to appear polygonal. A rounded diaphragm is designed to pro duce rounded out-of-focus light points when opened to near maximum aperture. This creates attractive bokeh effects in many situations, such as when pho tographing a subject against an out-of-focus surface of water from which light is being reflected.
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as "secondary spectrum" may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD ("F" Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
Super Multi-Layer Coating
SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.
Focus Mode Switch
Using this swich, it is possible to switch the focus mode between AF and MF.
Inner focus system
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).
