Sigma 120-300mm f/2.8 DG OS HSM Sports Lens for Nikon F

The Sigma 120-300mm f/2.8 DG OS HSM Sports Lens for Nikon F is a professional-grade super-telephoto zoom lens, offering versatile reach along with speed as the first lens introduced into the Sports category within Sigma’s Global Vision lineup. Characterized by its bright, constant f/2.8 maximum aperture across the entire zoom range, it’s well suited to sports, wildlife, and other fast-moving action subjects.

Optically, the lens is built from 23 elements in 18 groups, including two FLD (Fluorite Low Dispersion) elements and one SLD (Special Low Dispersion) element, minimizing chromatic and other aberrations for sharp, high-contrast results throughout the zoom range. Sigma’s Super Multi-Layer Coating helps control flare and ghosting, and a rounded 9-blade diaphragm contributes to smooth background rendering, with an angle of view spanning 20.4° at the wide end to 8.2° at full telephoto.

Autofocus is handled by Sigma’s Hyper Sonic Motor (HSM), delivering fast, accurate autofocus built for tracking moving subjects rather than just static ones, along with full-time manual focus control simply by rotating the focus ring at any time. A dedicated focus limiter switch allows switching between full-range focus, 10m-to-infinity, and a close-focus range down to 10m for more macro-style work, a useful addition not found on Sigma’s earlier EX-series version of this lens. Sigma’s Optical Stabilizer (OS) system compensates for camera shake during handheld shooting, with two selectable OS modes available via a separate switch. Both focusing and zooming operate internally, so the lens’s overall length never changes, and the front element does not rotate, useful for polarizing filters.

Build quality reflects the Sports line’s emphasis on durability and usability, with dust- and splash-resistant construction suited to repeated professional use in challenging outdoor conditions. The lens has a minimum focusing distance ranging from 150cm (59.1 in.) at the wide end to 250cm (98.4 in.) at telephoto, yielding a maximum magnification ratio of 1:8.1 (at 200mm), and accepts a 105mm filter thread. It measures approximately 121.4 x 291mm (4.8 x 11.5 in.) and weighs approximately 3,390g (119.6 oz.), reflecting its robust, reinforced Sports-line construction. The lens is compatible with Sigma’s optional USB Dock for fine-tuning AF speed, focus limiter, and OS settings, along with firmware updates, and supports Sigma’s TC-1401 1.4x and TC-2001 2x teleconverters.

As a full-frame DG-series lens, the Sigma 120-300mm f/2.8 DG OS HSM Sports is designed for use with full-frame Nikon F-mount DSLRs while remaining compatible with Nikon’s DX-format (APS-C) bodies as well.
