Tokina AT-X 116 PRO DX-II 11-16mm f/2.8 Lens for Sony A

Tokina AT-X 116 PRO DX-II 11-16mm f/2.8 Lens for Sony A-Mount
High-Speed Ultra-Wide APS-C Zoom – Constant f/2.8 Aperture & One-Touch Focus Clutch
The Tokina AT-X 116 PRO DX-II 11-16mm f/2.8 is a high-performance ultra-wide-angle autofocus zoom lens engineered specifically for Sony A-mount DSLRs and Alpha-series cameras utilizing APS-C size sensors. Spanning a dramatic 104° to 84° angle of view, this lens is highly prized for landscape, architectural, real estate, and indoor astrophotography. Its standout feature is a bright, constant f/2.8 maximum aperture, which delivers consistent exposure values across the entire zoom range and offers superior low-light gathering capabilities compared to slower variable-aperture alternatives.

As the second-generation iteration of Tokina’s acclaimed ultra-wide architecture, the PRO DX-II incorporates upgraded multi-layer optical coatings to aggressively suppress ghosting and lens flare while maximizing edge-to-edge contrast. The optical formula utilizes two Super-Low Dispersion (SD) glass elements alongside two aspheric elements to correct monochromatic and chromatic aberrations. Equipped with an internal focusing motor for smooth, predictable transitions and Tokina’s signature mechanical Focus Clutch, this ultra-wide zoom provides an exceptional tactical experience in the field.

This lens is fully tested and functional. The package comes completely production-ready and includes the front and rear protective caps along with the original matching lens hood.

Key Features & Optical Performance
Dramatic Ultra-Wide APS-C Coverage: Tailored natively for Sony A-mount crop-sensor camera bodies, offering a specialized ultra-wide focal timeline perfect for tight interiors, vast landscapes, and night skies.

Constant f/2.8 Aperture Speed: Maintains a fast f/2.8 opening from 11mm to 16mm, allowing photographers to shoot confidently in dim settings with lower ISO values and achieve smooth subject separation.

Advanced Aspheric & SD Glass Elements: Structured with two Super-Low Dispersion glass elements and two aspheric elements to minimize color fringing, secondary spectrum artifacts, and geometric distortions for pristine structural sharpness.

Upgraded Multi-Layer Coatings: Features re-engineered optical coatings that significantly cut down internal surface reflections, maintaining high image contrast and rich color neutrality when framing near bright or direct light sources.

One-Touch Focus Clutch Mechanism: Provides seamless, single-handed shifting between autofocus and manual focus by physically snapping the focus ring forward for AF and sliding it back for MF. This eliminates the need to look for a software menu or a hardware toggle switch on the camera body.

Internal Focusing Motor Setup: Driven by an internal focusing system that keeps the physical length of the lens frame constant during focus operations, ensuring smooth balance transitions that are ideal for video tracking.

Cinematic 9-Blade Diaphragm: Outfitted with a 9-blade aperture iris to yield a smooth, circular rendering of out-of-focus highlights and creamy background bokeh.

11.8-Inch Close-Focus Utility: Features a short minimum focusing distance of just 11.8 inches (30 cm), allowing for dramatic close-up wide-angle compositions with an exaggerated perspective layout.

Hardware Inventory & Condition Diagnostics
Functional State: FULLY OPERATIONAL. The internal autofocus drive locks onto targets cleanly, the zoom ring turns smoothly across the entire 11-16mm track, and the push-pull One-Touch Focus Clutch mechanism clicks securely into place.

Cosmetic Presentation: USED CONDITION. The exterior lens housing displays normal, light signs of standard field handling. The front and rear glass elements are well-preserved, clean, and entirely free of major defects.
