Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens (Nikon F)
Compact, Long-Reach Telephoto Zoom for Wildlife, Sports, and Travel

The Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary is a highly versatile telephoto zoom lens engineered for Nikon F-mount cameras. Belonging to Sigma’s esteemed Global Vision Contemporary line, this optic bridges the gap between massive telephoto reach and a lightweight, portable form factor. It serves as an exceptional tool for wildlife, sports, and outdoor action photography, offering enthusiast and professional shooters a lens that can easily be handled all day without a tripod.

Optically optimized to deliver crisp, high-contrast imagery throughout its expansive focal sweep, the lens incorporates specialized low-dispersion elements alongside advanced element coatings. This design is paired with an ultra-responsive Hyper Sonic Motor (HSM) and an integrated Optical Stabilizer to ensure sharp, handheld tracking of fast-moving subjects.

Key Features & Advanced Engineering

Expansive Focal Reach & Sensor Compatibility: Designed natively for full-frame (FX) Nikon F-mount DSLRs, it also functions seamlessly on DX-format models, where it provides a powerful 150-600mm equivalent telephoto focal range.

Special Low Dispersion (SLD) Optics: Features four premium SLD glass elements working in tandem to dramatically suppress color fringing and chromatic aberrations, maximizing edge-to-edge clarity and strict color fidelity across the entire zoom range.

Dual Action Zoom Matrix: Offers a unique handling experience by supporting both a traditional twist zoom ring mechanism and a quick, fluid push-pull movement. This allows for rapid, intuitive adjustments to your field of view when tracking erratic subjects.

Optical Stabilizer (OS) System: An integrated optical stabilization system counteracts the effects of camera shake, enabling sharper handheld shooting at slower shutter speeds or when working at the maximum 400mm telephoto extension.

Hyper Sonic Motor (HSM) Autofocus: Powered by a high-torque Hyper Sonic Motor running an optimized autofocus algorithm to deliver rapid, whisper-quiet tracking performance. Full-time manual focus override allows immediate control simply by rotating the focus ring.

Electromagnetic Aperture Mechanism: Utilizes Nikon’s advanced electromagnetic aperture diaphragm control, ensuring highly stable exposure consistency and precise aperture adjustments during high-speed continuous burst shooting.

Weather-Resistant TSC Chassis & Protective Coatings: Constructed from Thermally Stable Composite (TSC) material for structural accuracy across extreme temperature fluctuations. The rugged brass bayonet mount features a protective rubber sealing ring for dust- and splash-resistance, while the front element sports a water- and oil-repellent coating.

Rounded Nine-Blade Diaphragm: Incorporates a 9-blade circular aperture array that produces a smooth, pleasing out-of-focus background quality (bokeh) for striking subject isolation.

Sigma Ecosystem Support: Fully compatible with optional Sigma TC-1401 (1.4x) and TC-2001 (2.0x) teleconverters to further extend your reach, as well as the Sigma USB Dock for custom focus tuning and firmware updates.
