Sigma 16mm f/1.4 DC DN Contemporary Lens (Sony E)
High-Speed Ultra-Fast Wide-Angle Prime – Bright f/1.4 Maximum Aperture, 16mm Focal Length (24mm Full-Frame Equivalent), Sigma Global Vision Contemporary Series Optics, Three ‘F’ Low Dispersion (FLD) Elements, Two Special Low Dispersion (SLD) Elements, Two Aspherical Elements, Super Multi-Layer Coating, High-Speed Stepping Autofocus Motor (STM), Rounded 9-Blade Diaphragm, Dust- and Splash-Resistant Brass Bayonet Mount, Includes Front Cap, Rear Cap, and Dedicated Petal Lens Hood, Native Sony E-Mount (Good Condition)

The Sigma 16mm f/1.4 DC DN Contemporary Lens is a high-performance, ultra-fast wide-angle prime engineered specifically for APS-C format Sony E-mount mirrorless cameras (where it provides a classic 24mm full-frame equivalent field of view). Balancing high optical resolution with a compact, everyday footprint, this prime is designed for low-light street photography, landscape vistas, architectural interiors, night astrophotography, environmental portraits, and handheld vlogging. Its exceptionally fast f/1.4 maximum aperture delivers significant light-gathering capability in dimly lit environments while affording deep control over depth of field, enabling dramatic subject isolation and smooth background blur rarely achievable on crop-sensor platforms.

The sophisticated optical construction incorporates 16 elements in 13 groups, including three ‘F’ Low Dispersion (FLD) glass elements, two Special Low Dispersion (SLD) elements, and two precision-molded glass aspherical elements. This configuration actively suppresses sagittal coma flare, chromatic fringing, axial color aberrations, and spherical distortion to ensure tack-sharp resolving power across the entire frame, even when shooting wide open at f/1.4. Individual elements are treated with Sigma’s Super Multi-Layer Coating to eliminate ghosting and flare in high-contrast or backlit environments. Autofocus is driven by a high-speed stepping motor (STM) paired with optimized focusing algorithms, delivering rapid, smooth, and whisper-quiet focus acquisition fully compatible with Sony Fast Hybrid AF and Real-Time Eye AF. Built on a durable brass bayonet mount with an integrated rubber weather-sealing gasket, this versatile wide-angle lens delivers professional optical results in an agile package.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: COMPLETE WIDE PRIME OUTFIT. Supplied with the Sigma 16mm f/1.4 DC DN Contemporary lens, genuine Sigma 67mm front snap-on lens cap, genuine Sigma rear E-mount lens cap, and dedicated Sigma petal-type bayonet lens hood (LH716-01). (Sony camera bodies, gimbal rigs, and screw-in filters sold separately unless pictured).

Exterior & Barrel Status: GOOD CONDITION. The Thermally Stable Composite (TSC) and metal barrel shell, ribbed manual focus ring, and bayonet mount show typical cosmetic indications of standard field use, including light-to-moderate surface scuffs, shallow finish rub marks, and minor edge wear along the chassis and hood rim. All printed focal length markers, switch labels, and Sigma Contemporary insignia remain clean, sharp, and fully legible.

Optical Status: GOOD CONDITION. Both external front and rear optical glass surfaces are free of deep scratches, gouges, haze, fungus, or element separation. The internal optical assembly contains scattered, visible dust particles typical of regular field use; rigorous optical bench testing and sample test exposures confirm that these internal specks do not degrade resolving power, contrast, or color fidelity across normal working apertures. Super Multi-Layer Coatings remain intact.

Mechanical & Electronic Status: FULLY FUNCTIONAL. The internal stepping autofocus motor (STM) acquires target focus swiftly, accurately, and silently; full compatibility with Sony Fast Hybrid AF, Real-Time Eye AF (human/animal), and Tracking operates smoothly; the electronic manual focus ring rotates with smooth, well-damped precision; the 9-blade rounded diaphragm stops down cleanly without oil migration or sticking; gold-plated E-mount electronic contacts communicate Exif metadata and in-body corrections reliably with host Sony bodies with zero error codes.
