## Summary description

K&F Kf06.111 is a mechanical lens adapter that allows mounting Contax Yashica (C/Y) mount lenses on Sony E/NEX mirrorless cameras. It provides flange focal distance adaptation without electronic contacts, maintaining manual aperture and focus control. Suitable for photographers who want to use legacy C/Y glass on modern Sony bodies for manual shooting and creative control.

## Long description

K&F Kf06.111 is a mechanical lens adapter designed to mount Contax Yashica (C/Y) mount lenses on Sony E/NEX mirrorless cameras. It provides the precise flange focal distance conversion required to achieve infinity focus when using legacy C/Y lenses on modern Sony bodies. The adapter does not contain electronic contacts, so aperture and focus remain fully manual, preserving the mechanical operation and optical character of classic lenses.
Advantages
The adapter is constructed to deliver stable, play-free mounting between C/Y lenses and Sony E-mount cameras, ensuring consistent alignment and reliable optical performance. By keeping the optical path uninterrupted and avoiding electronic elements, it maintains the original lens mechanics and allows photographers full tactile control over focus and aperture. The compact and lightweight design adds minimal bulk to the camera setup, making it convenient for handheld and travel use.
Suitable for
 Photographers who want to adapt Contax Yashica manual lenses to Sony mirrorless bodies
 Portrait, street, and landscape photographers using vintage optics for distinctive rendering
 Videographers seeking manual aperture and focus control for cinematic effects
 Collectors and hobbyists who experiment with legacy glass on modern camera systems
Key specifications
 Mount conversion: Contax Yashica (C/Y) lens to Sony E/NEX camera body
 Contact type: fully mechanical, no electronic contacts
 Material: precision-machined metal alloy construction for durability and stability
 Finish: anti-reflective interior coating to reduce internal reflections and stray light
 Compatibility: supports manual aperture control and manual focus operation of C/Y lenses
 Weight and size: compact and lightweight profile designed to minimize added bulk
How to use
To use the adapter, align the release marks on the Contax Yashica lens and the adapter, rotate to secure the lens in place, then mount the adapter with lens attached onto the Sony E-mount camera and lock it. Set the camera to the appropriate focus mode for manual operation and use focus peaking or magnification if available to assist with precise focusing. Because the adapter lacks electronic communication, set exposure manually on the camera or use aperture-priority with manual-aperture lenses if supported by the body. Remove the adapter by reversing the attachment steps, taking care to avoid contamination of lens or camera contacts.
Usage recommendations
Use manual focusing aids such as focus peaking, live view magnification, or an external monitor when composing and focusing. Check for vignetting or light falloff wide open on certain vintage lenses and stop down as needed for increased sharpness. Keep the adapter and lens mounts clean and store with caps to prevent dust ingress; avoid forcing mounts during attachment to preserve bayonet integrity.
