(Open Box) Sony Sonnar T* 135mm f/1.8 ZA - SAL135F18Z Camera Lens

The Sony Sonnar T 135mm f/1.8 ZA* is an optical masterpiece developed through the historic collaboration between Sony and ZEISS. Widely regarded as one of the sharpest lenses ever created for the A-mount system, it combines a generous telephoto reach with an incredibly fast aperture to produce images with surgical precision and ethereal background blur. This lens is the definitive choice for portrait specialists who require absolute resolution even when shooting wide open, offering a unique "three-dimensional" rendering that has made it a cult classic among professional photographers.

Elite ZEISS Optical Performance

Bright f/1.8 Maximum Aperture: Provides extraordinary light-gathering capabilities and a razor-thin depth of field, allowing you to isolate subjects with a creamy, professional background that makes them truly "pop" from the frame.

Sonnar Optical Design: Features 11 elements in 8 groups, including 2 ED (Extra-low Dispersion) glass elements to effectively suppress chromatic aberration and ensure high-contrast, color-accurate imagery from corner to corner.

ZEISS T (T-Star) Coating*: A specialized multi-layer coating that virtually eliminates ghosting and internal reflections, maintaining high-contrast performance even when shooting into harsh backlit or studio lighting.

High-Precision Performance

Internal Focusing Mechanism: The lens elements move internally, ensuring the overall length of the lens remains constant during focus. This improves balance and prevents the barrel from rotating, which is critical when using 77mm polarizers.

9-Blade Circular Diaphragm: Specifically designed to produce smooth, rounded out-of-focus highlights (bokeh), adding a cinematic, artistic quality to your highlights.

Short Minimum Focus Distance: Offers an impressive close-focusing distance of just 0.72m with a 0.25x magnification ratio, allowing for tight, high-impact headshots with incredible detail.

Professional Build and Handling

All-Metal Construction: Built with a rugged aluminum alloy barrel and a durable metal mount to ensure long-term reliability for demanding professional use.

Focus Hold Button: Features a conveniently placed button on the lens barrel that allows you to lock the focus instantly, providing tactical control during complex portrait sessions.

A-Mount Heritage: Fully compatible with Sony Alpha DSLR and SLT cameras, and can be used on modern E-mount mirrorless bodies with a high-performance LA-EA series adapter for seamless integration into a modern 61MP+ workflow.
