## Summary description

Mount adapter by K&F Pro enabling use of Contax/Yashica-mount lenses on Sony E-mount (NEX) cameras. Mechanical adapter preserves flange distance for manual focus and aperture control of legacy lenses. Compact metal construction ensures stable attachment and compatibility for photography and videography with vintage Contax/Yashica optics on modern Sony E bodies.

## Long description

The Lens Mount Adapter K&F Pro for Sony E to Contax/Yashica enables photographers to mount Contax/Yashica-mount lenses on Sony E-mount (NEX) mirrorless cameras. This mechanical adapter maintains the correct flange focal distance, allowing manual focus and manual aperture control of legacy lenses while keeping close physical alignment between lens and camera body. Its compact metal construction provides a secure, durable connection suited for both still photography and video work with vintage Contax/Yashica optics on modern Sony E bodies.
Advantages
The adapter is designed for a precise mechanical fit that preserves infinity focus and reliable flange distance, reducing the need for optical correction. Its all-metal build offers sturdiness and resistance to wear from repeated lens changes. The plain mechanical interface means there is no electronic communication, ensuring compatibility with a wide range of vintage Contax/Yashica lenses and avoiding unexpected firmware or compatibility issues. The compact profile minimizes added bulk, keeping balance when using smaller mirrorless bodies.
Suitable for
Photographers who want to use Contax/Yashica manual lenses on Sony E-mount cameras
Videographers seeking vintage glass characteristics such as unique bokeh and color rendering
Macro, portrait, and street photography with manual focus lenses
Hybrid shooters who combine modern camera features with legacy optics
Key specifications
Mount conversion: Sony E-mount camera body to Contax/Yashica-mount lens
Construction: metal alloy body for durability and stable attachment
Optical design: mechanical-only adapter, no optics included
Focus: supports full manual focus and maintains infinity focus when properly mounted
Aperture control: manual aperture control via lens aperture ring
Compatibility: designed for mirrorless Sony E cameras and Contax/Yashica lenses
Form factor: compact and lightweight profile to reduce handling imbalance
How to use
Attach the adapter to the Sony E camera bayonet by aligning the adapter’s mount mark with the camera’s mounting mark and rotating until it locks. Mount the Contax/Yashica lens to the adapter by aligning the lens mount index and turning until it clicks into place. Set the lens aperture and focus manually on the lens itself. Use camera settings that support manual lenses, such as focus peaking or magnification, to assist with focusing. Remove the lens and adapter by reversing the mounting steps, taking care to avoid contamination of the rear lens element and camera sensor.
Usage recommendations
Use manual focus aids on your Sony camera—focus peaking, focus magnification and live view—to achieve precise focus with manual Contax/Yashica lenses. When shooting handheld, balance heavier lenses on a support or tripod to reduce strain on the adapter mount and ensure consistent framing and sharpness.
