Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens (Sony E)

Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens (Sony E-Mount)
The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary is a high-performance ultra-telephoto zoom lens engineered from the ground up exclusively for full-frame Sony E-mount mirrorless cameras, while also providing a massive 150-600mm equivalent range on APS-C cropped sensor bodies. Aptly nicknamed the “Handy Zoom,” this Contemporary-series lens is highly celebrated for packing remarkable telephoto reach and high-end optical clarity into a surprisingly lightweight, hand-holdable design. Merging an advanced optical stabilizer with a rapid stepping motor and mirrorless-specific optimizations, it stands as the ultimate portable choice for wildlife, sports, travel, and aviation photography.

CONDITION NOTE
Complete Factory Accessory Package: This telephoto lens is fully equipped and field-ready, shipping complete with standard front and rear lens caps, alongside its original dedicated matching barrel lens hood to prevent stray flare and protect the front optics from physical impacts.

Note: The optional TS-111 tripod socket is not included, allowing the lens to maintain its sleek, lightweight, hand-holdable profile out of the box.

High-Clarity Optics & Dual Zoom Ergonomics
Premium Low-Dispersion Matrix: Features one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) glass elements. This advanced optical combination systematically eliminates chromatic aberrations, secondary spectra, and secondary color fringing for outstanding edge-to-edge contrast and color accuracy.

Dual-Action Zoom Versatility: Supports both traditional twist-ring zooming and straight push-pull zooming mechanics. The front of the lens barrel is ergonomically sculpted to allow shooters to safely grip and pull the front for rapid focal length adjustments on fast-moving subjects.

Vibrant 9-Blade Circular Aperture: Outfitted with a rounded nine-blade diaphragm that helps render soft, round specular highlights and a visually smooth background blur (bokeh).

Excellent Close-Focus Tele-Macro Capabilities: Offers a close minimum focusing distance of 3.7 feet (1.13 meters) at the 100mm end and 5.2 feet (1.6 meters) at the 400mm end, unlocking an impressive maximum magnification ratio of 1:4.1 for beautiful close-up detail tracking.

4-Stop Optical Stabilization & Stepping Motor AF
4-Stop Optical Image Stabilizer (OS): Built-in algorithmic hardware stabilization counteracts handheld tremors by up to four stops. This guarantees sharp results when shooting at maximum telephoto lengths or utilizing slower shutter speeds in low available light.

High-Speed Mirrorless Stepping Motor: Driven by an optimized stepping motor that provides rapid, whisper-quiet, and incredibly accurate autofocus performance. It fully supports Sony’s native camera algorithms for smooth continuous tracking, Face Priority, and Real-Time Eye AF.

Three-Position Focus Range Limiter: Outfitted with a mechanical switch to constrain the lens’s autofocus hunting envelope (Full, 6m to infinity, or close-range tracking), radically accelerating focus acquisition times for distant action.

Tactile Command Switches & Weatherproof Mount
Programmable AFL Function Button: Features a physical on-barrel Autofocus Lock (AFL) button that can be entirely reassigned via Sony camera body menus to trigger specialized utilities such as Eye AF, grid line overlays, or shot previews.

Mechanical Zoom Lock Toggle: Incorporates a dedicated physical zoom lock switch to anchor the barrel completely at its widest 100mm setting, eliminating accidental lens creeping when hiking or carrying the kit on a shoulder strap.

Dust- and Splash-Resistant Brass Mount: Built with a high-precision, solid brass bayonet mount for exceptional rigidity and structural alignment. The mount incorporates a rugged rubber weather-sealing gasket to guard the camera sensor and electronic connection points from encroaching dust, grit, and light moisture.

Removable Trim Ring Compatible: Fully compatible with the optional TS-111 Tripod Socket for monopod or tripod balance. This kit retains a seamless, tactile appearance by integrating a clean PT-31 rubber protection ring over the collar mounting threads.
