Sigma 16mm f/1.4 DC DN Contemporary Lens (Sony E)

Sigma 16mm f/1.4 DC DN Contemporary Lens for Sony E
High-Speed Wide-Angle Prime Lens for Sony APS-C Mirrorless – 24mm Equivalent Focal Length, Ultra-Fast f/1.4 Maximum Aperture, Fast Stepping AF Motor, 3 FLD & 2 SLD Elements, Super Multi-Layer Coating, Weather-Sealed Brass Bayonet Mount, Rounded 9-Blade Diaphragm (Good Condition / Oxidized Focusing Grip / Minor Internal Dust)

The Sigma 16mm f/1.4 DC DN Contemporary is a high-speed, wide-angle prime lens engineered specifically for APS-C-format Sony E-mount mirrorless cameras, delivering a versatile 24mm full-frame equivalent focal length. Developed as part of Sigma’s Global Vision Contemporary lineup, this lens combines high optical resolving power with an ultra-bright f/1.4 maximum aperture, making it an essential choice for low-light street photography, landscapes, architectural interiors, astrophotography, environmental portraiture, and professional vlogging. The wide aperture provides excellent exposure flexibility in dim lighting and shallow depth-of-field control for clean subject isolation.

The complex optical formula consists of 16 elements in 13 groups, featuring three “F” Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) glass elements, and two precision-molded aspherical elements. This advanced arrangement suppresses chromatic aberrations, color fringing, coma, and distortion to deliver sharp, high-contrast imagery from wide-open apertures across the entire frame. Individual elements are treated with Sigma’s Super Multi-Layer Coating to eliminate ghosting and flare in challenging backlit conditions. Autofocus is driven by a smooth stepping motor optimized for rapid, quiet, and precise focusing in both stills shooting and continuous video tracking (Fast Hybrid AF and Eye AF compatible). Built with a durable brass bayonet mount featuring dust- and splash-resistant rubber sealing, the lens also incorporates a rounded 9-blade diaphragm for creamy, natural background bokeh.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: WIDE-ANGLE PRIME LENS UNIT. Supplied with the Sigma 16mm f/1.4 DC DN Contemporary lens for Sony E-mount. (Note: Front and rear caps are not included unless pictured/specified).

Exterior & Physical Status: GOOD CONDITION WITH GRIP WEAR. The Thermally Stable Composite (TSC) barrel, metal mount, and switchless chassis show standard cosmetic surface marks and handling wear consistent with regular use. The wide rubber manual focusing grip exhibits surface oxidation (a common cosmetic aging trait that does not affect tactile functionality or grip).

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED OPTICAL DUST. The internal optical elements contain standard light dust particles typical of pre-owned primes (tested and verified not to degrade image resolution, contrast, or everyday exposure). The stepping autofocus motor operates quickly and silently; the electronic manual focus ring responds smoothly; the electronic 9-blade aperture stops down accurately across all f-stops on Sony Alpha bodies.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

24mm Equivalent Wide-Angle Perspective: Versatile focal length ideal for vlogging, landscapes, interiors, group shots, and documentary street capture.

Ultra-Fast f/1.4 Maximum Aperture: Excels in demanding low-light environments and produces shallow depth of field with smooth background separation.

Advanced FLD, SLD & Aspherical Optics: Integrates 3 FLD, 2 SLD, and 2 aspherical glass elements to curb optical aberrations, chromatic fringing, and geometric distortion.

Super Multi-Layer Coating: Minimizes flare and ghosting to preserve deep contrast and neutral color balance in harsh or direct sunlight.

Fast & Quiet Stepping AF Motor: Delivers rapid, near-silent autofocus tracking optimized for both high-resolution photography and video focus pulls.

Rounded 9-Blade Diaphragm: Softens out-of-focus highlights to create circular bokeh and smooth background transitions.

Weather-Sealed Brass Bayonet: High-precision brass mount incorporates rubber gasket sealing for reliable protection against dust and moisture.

Full Sony E-Mount APS-C Compatibility: Native integration with Sony Alpha APS-C mirrorless cameras (a5000, a5100, a6000, a6100, a6300, a6400, a6500, a6600, a6700, and ZV-E10 series).
