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.

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

This compact lens is packed with a range of functionalities that will satisfy both professional and advanced amateur photographers. The 85mm F1.4 DG DN | Art has newly introduced an 1 “Iris ring lock switch .*1” This prevents from unintended movement of the iris ring during shooting, allowing users to devote their attention to the creation of their image. The Iris ring is mounted with a de-click function for removing clicks by the 2 Iris Ring Click Switch, enabling seamless operations that are especially useful such as during video shooting. Furthermore, the 3 “Focus Mode Switch ” on the lens body and the 4 “AFL button *2” that allows various functions to be assigned from a camera body will also assist users’ shooting.
In addition to the 5 dust and splash resistant structure *3, along with a water- and oil-repellent coating, the lens uses materials such as aluminum and TSC (Thermally Stable Composite) where they are best suited, achieving a level of build quality that is worthy of the Art line. In addition to the durability of the body, the lens pursues quality in terms of how users “feel” as well, such as the smooth motion in which each ring or switch works, and the precise hand feeling. The 85mm F1.4 DG DN | Art helps ensure users a smooth shooting experience in every condition.

*1 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.
*2 Limited to compatible cameras. Also, the functions depend on the camera.
*3 Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

MTF Chart

DIFFRACTION MFT

GEOMETRICAL MFT

MTF CHART GUIDE

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.

HLA (High-response Linear Actuator)

HLA is Sigma’s proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.

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).

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.

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.

Aperture ring

Aperture ring, designed to help users work intuitively

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.

Aperture ring lock switch

A ring lock system to prevent from unintended movement of the aperture ring during shooting.

AFL button

the AFL button can be assigned with various functions widens the range of operations available on the lens.

Linear focus / Non-linear focus (for L-Mount only）

A focus movement method of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotational angle of the focus ring during manual focusing.
With “non-linear focus,” the amount of focal point movement varies depending on the focus ring rotational speed.
With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.

Focus Mode Switch

Using this swich, it is possible to switch the focus mode between AF and MF.
