The Sigma 105mm f/2.8 EX DG OS HSM Macro is a short-telephoto prime lens for Nikon F-mount cameras. It’s designed for close-up photography, offering a true 1:1 life-size magnification and a minimum focusing distance of just 1 foot. With a bright f/2.8 aperture, it performs well in low light and provides excellent subject isolation with shallow depth of field.

Optical Performance

This lens features two Special Low Dispersion (SLD) elements that minimize chromatic aberrations and color fringing. A Super Multi-Layer Coating further enhances image quality by reducing flare and ghosting, ensuring rich contrast and accurate color even in bright backlit scenes.

Autofocus & Stabilization

The Hyper Sonic Motor (HSM) delivers fast, quiet, and precise autofocus, while full-time manual focus lets you fine-tune your shots. An internal floating focus system maintains sharpness throughout the entire focusing range. To support handheld shooting, the Optical Stabilizer reduces camera shake and produces sharper results.

Design & Build

Built for durability, the lens includes a floating element design and a rounded nine-blade diaphragm that creates smooth, natural bokeh. It’s also compatible with Sigma’s APO 1.4x EX DG and APO 2x EX DG teleconverters for extended reach.
