Sigma 105mm f/2.8 DG DN Macro Art: The Pinnacle of Mirrorless Macro Performance

The Sigma 105mm f/2.8 DG DN Macro Art is a top-tier mid-telephoto prime designed from the ground up exclusively for full-frame mirrorless camera systems (Sony E-mount and Leica L-mount). As part of Sigma’s elite Art line, this lens prioritizes absolute optical resolution and edge-to-edge rendering clarity above all else. Delivering a true 1:1 life-size reproduction ratio, it is built to reveal microscopic textures with staggering contrast while correcting color bleeding entirely. Beyond its class-leading close-up capabilities, its 105mm focal length and bright f/2.8 aperture make it an incredibly versatile asset for high-end studio portraiture, commercial product photography, and fine-art reproduction work.

Sigma 105mm f/2.8 DG DN Macro Art Key Product Features

• True 1:1 Life-Size Magnification: Captures microscopic subjects at their actual physical scale on the camera sensor with a close minimum focusing distance of 29.5 cm.

• Advanced Optical Aberration Correction: Features 12 elements in 7 groups, incorporating one Special Low Dispersion (SLD) glass element to neutralize longitudinal chromatic aberration that standard camera software cannot fix.

• Aperture Ring with Click & Lock Controls: Equipped with a physical iris ring that includes a click/de-click switch for silent video iris pulling, plus a dedicated ring lock switch to prevent accidental mode shifts.

• Three-Zone Focus Limiter Switch: Maximizes autofocus hunting speeds by allowing shooters to restrict the lens tracking range to close-up macro (0.295m–0.5m), distant details (0.5m to infinity), or full range.

• Weather-Sealed Professional Build: Constructed with a rugged, high-precision brass bayonet mount and structural internal seals to resist water splashes, dust, and demanding environmental conditions.

• Customizable Barrel AFL Button: Incorporates a physical Autofocus-Lock button directly on the body, which can be reprogrammed via the camera menu to execute specific custom shortcuts.
