Delivering optical excellence paired with remarkable close-focusing capabilities, the Sigma 105mm f/2.8 DG DN Macro Art Lens for L-mount offers an optimal solution for macro photography enthusiasts. Crafted as a short-telephoto prime, this lens is meticulously designed for full-frame L-mount mirrorless cameras, providing a versatile 157.5mm equivalent focal length on APS-C models.

The lens’s true macro design stands out with a life-size 1:1 maximum magnification, an 11.6″ minimum focusing distance, and a 5.5″ minimum working distance, ensuring precise rendering of close-up subjects. The optical construction incorporates a Special Low Dispersion (SLD) element that significantly diminishes chromatic aberrations and color fringing, enhancing clarity and color accuracy. A Super Multi-Layer Coating further elevates the optical performance by minimizing flare and ghosting, resulting in contrast-rich and color-neutral imagery, even in challenging backlit conditions.

For seamless handling, the lens features a Hyper-Sonic Motor (HSM) that delivers swift and silent autofocus performance, complemented by an optimized AF algorithm for smoother focusing. The HSM also allows for full-time manual focus control, enhancing creative flexibility. A focus limiter switch enables users to constrain the focusing range within three zones, optimizing speed and precision.

The lens housing is weather-sealed, ensuring durability and reliability in adverse conditions. The brass bayonet enhances mounting accuracy and rigidity. For video applications, the manual aperture ring can be de-clicked for smooth, silent aperture adjustments, and a dedicated aperture ring lock switch prevents accidental shifts. An integrated Autofocus-Lock (AFL) button, with customizable functions, expands the range of operations available on the lens.

Further enhancing its versatility, the L-mount version of this lens is compatible with optional TC-1411 and TC-2011 teleconverters, allowing users to increase magnification without altering the effective working distance. Additionally, the lens can be fine-tuned and its firmware updated using the optional Sigma UD-11 USB Dock, providing a tailored approach to different shooting scenarios.

As a proud member of Sigma’s Art line within the Global Vision series, this lens is meticulously engineered to deliver outstanding optical performance, making it an ideal choice for creative and artistic applications. Whether capturing intricate details or pursuing artistic endeavors, the Sigma 105mm f/2.8 DG DN Macro Art Lens for L-mount stands as a testament to precision, versatility, and optical excellence in the realm of macro photography.
