Sony Sonnar T* FE 55mm f/1.8 ZA Lens

Sony ZEISS Sonnar T* FE 55mm f/1.8 ZA Lens
Premium Normal Prime – Fully Functional / Well-Used Condition (Heavy Dust & Body Scratches)
The Sony ZEISS Sonnar T* FE 55mm f/1.8 ZA is a legendary, high-performance standard prime lens custom-engineered for full-frame E-mount mirrorless cameras. Built around the world-renowned ZEISS Sonnar optical concept, this lens is celebrated for its exceptional corner-to-corner resolution, biting contrast, and minimal optical distortion.

Its bright f/1.8 maximum aperture offers an ideal balance of low-light capability and a highly compact footprint. Driven by a fast, linear autofocus motor and protected by weather-resistant sealing, it stands as an exceptional choice for street photography, high-end portraits, documentations, and cinematic video work. This package comes complete with its front cap, rear cap, and dedicated lens hood.

Please note: This lens is in well-used condition. The exterior chassis shows prominent scratches and cosmetic finish wear, and the interior optical path houses a heavy accumulation of dust. However, the glass elements are completely free of scratches and the lens remains fully functional.

Key Features & ZEISS Optical Excellence
Classic 55mm “Normal” Perspective: Delivers a highly natural field of view on full-frame sensors, or a tight 82.5mm short-telephoto equivalent perspective when mounted to crop-sensor APS-C Sony Alpha bodies.

Bright f/1.8 Maximum Aperture: The wide f/1.8 opening maximizes light transmission for handheld shooting in low ambient light while affording precise control over a shallow depth of field for dramatic subject isolation.

Sonnar Optical Layout & Aspherical Elements: Features a refined 7-element, 5-group design that integrates three aspherical elements (including two double-sided aspherical components) to aggressively combat astigmatism, coma, and field curvature.

ZEISS T Anti-Reflective Coating:* Every lens surface is treated with premium ZEISS T* coatings to significantly suppress internal reflections, ghosting, and flare, preserving deep contrast and rich color fidelity.

Linear Autofocus Motor & Internal Focus: Outfitted with a rapid linear AF motor and an internal focusing (IF) mechanism. The lens elements move internally without extending the outer barrel, delivering quick, precise, and near-silent tracking optimized for video audio tracks.

9-Blade Rounded Diaphragm: Built with a rounded nine-blade aperture structure that yields exceptionally smooth, circular, and natural-looking background bokeh.

Weather-Sealed Construction: Features a robust dust- and moisture-sealed design alongside a rubberized manual focus control ring to ensure dependable operation when shooting in adverse environmental conditions.

Item Condition & Diagnostic Notes
Functional & Mechanical Performance: FULLY OPERATIONAL. This lens has been thoroughly bench-tested and performs flawlessly. The internal autofocus motor tracks rapidly and locks onto targets accurately. Electronic communication with the camera body is instant, and manual focusing is perfectly smooth.

Optical State (Heavy Dust / Clear Glass): The internal optical path contains a heavy accumulation of fine dust particles. This standard buildup from extensive field use is visible under a direct inspection light. However, the glass elements are completely free of scratches, fungus, haze, or separation. In diagnostic testing, the internal dust does not impact image resolution, contrast, or color rendition under standard shooting parameters.

Cosmetic Presentation: This unit is in well-used condition. The exterior aluminum barrel and metal housing display prominent cosmetic wear, including visible surface scratches, scuffs, and finish rubbing marks on the metal casing and focus ring ridges from extensive real-world use. These markings are strictly cosmetic and do not affect the lens’s structural durability.

Included Accessories: Includes the front lens cap, rear lens cap, and the original matching bayonet lens hood.
