Sigma 16mm f/1.4 DC DN Contemporary Lens (FUJIFILM X)

Sigma 16mm f/1.4 DC DN Contemporary Lens for FUJIFILM X
High-Speed Wide-Angle Prime – Ultra-Fast f/1.4 Aperture, Stepping AF Motor & Weather-Sealed Brass Mount (Good Condition / Dust & Hair in Rear Element)

The Sigma 16mm f/1.4 DC DN Contemporary is a high-speed, wide-angle prime lens designed for APS-C FUJIFILM X-mount mirrorless cameras. Delivering a 24mm full-frame equivalent focal length, this lens combines a wide field of view with an ultra-fast f/1.4 maximum aperture, making it an exceptional choice for landscape, astrophotography, architectural, street, and low-light environmental shooting. The bright f/1.4 aperture provides enhanced low-light performance alongside precise depth-of-field control for selective focus effects.

Its optical design incorporates three F Low Dispersion (FLD) elements, two Special Low Dispersion (SLD) elements, and two aspherical elements to control chromatic aberrations, color fringing, and spherical distortion. A Super Multi-Layer Coating suppresses lens flare and ghosting to preserve contrast in backlit environments. Autofocus is driven by a fast, quiet stepping motor suited for both stills and video production, supported by a rounded nine-blade diaphragm for smooth background bokeh and a rubber-sealed brass bayonet mount for dust and splash resistance.

Condition Diagnostics & Physical Notes

Rear Glass Condition: DUST AND HAIR PRESENT ON REAR ELEMENT. The rear internal glass element exhibits minor dust particles and a fine hair strand.

Image Performance Impact: NO SIGNIFICANT IMPACT ON IMAGE QUALITY. Standard test shots demonstrate sharp, clear rendering; the dust and hair do not visually affect exposure or focus performance in real-world use.

Mechanical & AF Status: FULLY FUNCTIONAL. The stepping AF motor and manual focus ring operate smoothly and precisely.

Physical Condition: GOOD OVERALL CONDITION. The outer barrel, electronic contacts, and bayonet mount remain in clean condition with minor signs of handling.

Key Features & Performance Highlights

24mm Equivalent Wide-Angle Field of View: Spans an essential wide focal length ideal for landscapes, architecture, and environmental portraits.

Ultra-Fast f/1.4 Maximum Aperture: Excels in low-light environments while offering shallow depth-of-field control.

Advanced Optical Construction: Features 3 FLD, 2 SLD, and 2 aspherical elements to maintain high resolution and color accuracy.

Quiet Stepping AF Motor: Delivers smooth, rapid, and near-silent autofocus tracking for video and photo capture.

Weather-Sealed Brass Bayonet: Built with a durable brass mount and rubber gasket sealing to protect against dust and splash.
