Sigma 16mm f/1.4 DC DN Contemporary Lens (Sony E)
High-Speed Wide-Angle Prime – Bright f/1.4 Maximum Aperture, 16mm Focal Length (24mm Full-Frame Equivalent), Sigma Global Vision Contemporary Line, Advanced Optical Formula (3 FLD Elements, 2 SLD Elements, 2 Aspherical Elements), Super Multi-Layer Coating, Fast & Quiet Stepping Autofocus Motor (STM), Rounded 9-Blade Diaphragm, Dust- and Splash-Resistant Brass Bayonet Mount with Rubber Gasket, Includes Front Cap, Rear Cap, and Dedicated Petal Lens Hood, Native APS-C Sony E-Mount (Excellent 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 (providing a versatile 24mm full-frame equivalent field of view). Balancing high resolving power with a lightweight footprint, this prime excels at low-light street photography, landscapes, environmental portraits, architectural interiors, night astrophotography, and handheld vlogging. Its bright f/1.4 maximum aperture affords superior light gathering in dim environments while enabling shallow depth-of-field control and smooth subject-to-background separation.

The optical formula utilizes 16 elements in 13 groups, integrating three ‘F’ Low Dispersion (FLD) glass elements, two Special Low Dispersion (SLD) elements, and two glass-molded aspherical elements. This arrangement suppresses sagittal coma flare, chromatic fringing, and geometric distortion to maintain corner-to-corner sharpness wide open at f/1.4. Elements feature Sigma’s Super Multi-Layer Coating to prevent flare and ghosting in high-contrast or backlit scenes. Autofocus is driven by a smooth stepping motor (STM) for quiet, responsive focus tracking compatible with Sony Fast Hybrid AF and Real-Time Eye AF. Built on a durable brass bayonet mount with a protective rubber weather-sealing gasket, this wide prime delivers reliable performance in top-tier shape.

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). (Camera bodies, filters, and gimbals sold separately unless pictured).

Exterior & Barrel Status: EXCELLENT CONDITION. The Thermally Stable Composite (TSC) barrel chassis, ribbed manual focus ring, and bayonet mount show minimal to no signs of handling, with no deep scratches, dings, or noticeable finish wear. Printed focal length indices and Sigma Contemporary emblems remain crisp, sharp, and fully legible.

Optical Status: EXCELLENT CONDITION. Both front and rear external glass surfaces are clean and free of scratches, scuffs, cleaning marks, haze, fungus, or element separation. The internal assembly contains trace, light dust typical of standard handling; bench testing confirms these specks do not impact contrast, resolution, or color neutrality across all apertures. Super Multi-Layer Coatings remain pristine.

Mechanical & Electronic Status: FULLY FUNCTIONAL. The internal stepping motor (STM) acquires focus swiftly, accurately, and silently; full compatibility with Sony Fast Hybrid AF and Real-Time Eye AF functions seamlessly; manual focus ring rotates with smooth, well-damped precision; the 9-blade rounded diaphragm actuates cleanly without oil accumulation or sticking; electronic mount contacts communicate Exif metadata and in-body corrections reliably with zero camera errors.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Ultra-Fast f/1.4 Maximum Aperture: Excels in low ambient light while delivering shallow depth of field and pleasing background blur.

24mm Full-Frame Equivalent Reach: Wide 83.2° field of view tailored for street scenes, travel landscapes, vlogging, and architecture.

Advanced Optical Architecture: Combines 3 FLD, 2 SLD, and 2 aspherical elements to correct chromatic aberrations and distortion.

Super Multi-Layer Coating: Minimizes internal lens flare and ghosting, preserving rich contrast in backlit environments.
