Ronkonkoma, NY—Sigma Corporation of America debuted the Sigma 105mm F2.8 DG DN Macro Art lens for E- and L-mount full-frame mirrorless cameras. The new lens is a redesigned edition of a classic macro lens.
Mid-telephoto macro lenses give photographers a boost to creativity, offering versatile working distances. As a result, they have become part of photographers’ basic gear. Now, Sigma has introduced the first macro lens for mirrorless cameras in its Art line. “The 105mm f/2.8 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,” the company announced.
Beyond being a high-spec macro lens that’s a solution for a range of settings, the new lens is, of course, ideal for macro shooting and portraits. It has a minimum focusing distance of 11.6 inches. What’s more, it can give photographers an opportunity to rediscover a new way of looking at objects through its perspective that is unique to a macro lens.
Sigma 105mm F2.8 DG DN Macro Art Specs
The optical design of the 105mm f/2.8 DG DN Macro Art ensures sharpness at all shooting distances: from extreme close-ups all the way up to infinity. It incorporates 17 elements in 12 groups, with one SLD (super low dispersion) lens.
In addition, its aberration correction places a particular focus on longitudinal chromatic aberration; this aberration is not handled by in-camera aberration correction. The optical design also produces clear images that are free of color bleeding.
Moreover, bokeh was one of the focuses in the new design, which figures largely in mid-telephoto shooting. The volume of peripheral light helps create beautiful bokeh circles. In addition, natural bokeh effect in the background, as well as foreground, gives more flexibility to photographic expression. This is aided by a 9-blade rounded diaphragm.
Furthermore, when equipped with Sigma’s TC-1411 (1.4x) or TC-2011 (2.0x) teleconverters for L-mount lenses, photographers can shoot macro at even higher magnifications while keeping the working distance.
Sigma Art line lenses prioritize optical performance above all else. This applies to the 105mm f/2.8 DG DN Macro Art. Consequently, it will provide rendering performance from the center of the frame up to the edges. Conversely, its ability to minimize ghosting and flare with super multilayer coatings was validated through rigorous testing.
What’s more, the lens supports the latest camera functionalities, such as face- and eye-detection AF. It also incorporates a hypersonic motor (HSM) in its focus motor system to achieve precise, quiet autofocus operation.
Additional Features
The macro Art lens features a focus limiter setting, which is handy during macro shooting, as well as an AFL button for assigning select functions. Moreover, an aperture ring has a setting to turn on or off the clicking sound that isn’t required by some users when shooting macro.
It also comes with a switch for a ring lock system. In addition, users can customize their shooting operations in accordance with their shooting styles. A focus mode switch is also integrated into the lens. 
The lens also has a dust- and splashproof structure, as well as a water- and oil-repellent coating. The Sigma 105mm f/2.8 DG DN Macro Art comes with a lens hood/case and is compatible with the Sigma UD-11 USB dock (optional, L mount only). Both the E mount and L mount versions have a suggested retail price of $799.
