The SIGMA 105mm F2.8 DG DN MACRO | Art is a high-performance, mid-telephoto macro lens designed from the ground-up for mirrorless cameras.
Performance exceeds expectations
Mid-telephoto macro lenses give photographers a boost of creativity and a versatile working distance, which makes the lenses a favourite among professionals as part of their basic gear. Introduced as the first macro lens for mirrorless cameras in the Art line, the 105mm F2.8 DG DN MACRO | Art packs the highest level of performance expected of a mid-telephoto macro lens into its body, from its superb optical performance to excellent build quality.
Beyond being a high-spec macro lens that excels in a wide range of settings, the SIGMA 105mm F2.8 DG DN MACRO | Art is ideal for macro shooting or portraits. It also gives photographers an opportunity to discover a new way of looking at things such as unexpected beauty or something precious in everyday life, through its unique perspective. It provides performance that goes far beyond the expectation or imagination of what a "classic mid-telephoto macro lens" can be.
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 colour bleeding.
Bokeh is one of the big focuses of the 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.
NB: Teleconverters reduce the maximum aperture and may affect autofocus. For more information, there is a helpful article, HERE.
SIGMA Art line class optical and AF performance
The SIGMA Art line lenses prioritise 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 centre of the frame all the way to the edges. Its abilities to minimise ghosting and flare, which have been validated through rigorous testing from the early stages of its development, ensure that it performs well in backlit conditions.
On top of optimisation 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 mantel.
A full range of functionalities and an excellent build quality
On its body, the 105mm F2.8 DG DN MACRO | Art features a Focus Mode Switch,
Focus limiter setting which comes in handy during macro shooting, and the AFL button*1 to which users may assign select functions. The Aperture ring, which is designed to help users work intuitively, has an 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 an aperture ring lock switch*2 for a ring lock system. Its enhanced functions allow users to customise their shooting operations in accordance with their shooting styles.
*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.
The lens has a 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 feel.
With these 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.
