Manual Focus Adapter Samyang V-AF 23372 for Canon EF-Mount, enables manual lenses on EF cameras

Samyang Manual Focus Adapter V-AF 23372 for Canon EF-Mount allows photographers to use manual-focus lenses designed for other mounts on Canon EF-mount cameras. The adapter provides a secure mechanical connection while preserving manual aperture and focus control of legacy and third-party lenses. It does not transmit electronic signals, ensuring simple, reliable compatibility for still photography, video work and creative projects that require direct lens control.

Advantages

The adapter delivers a stable physical connection between lens and camera without altering optical characteristics. Manual focus and aperture rings remain fully operable on the attached lens, enabling precise, tactile control. Its construction is designed for repeatable mounting and safe lens support, minimising play and alignment shift. Because the adapter lacks electronic contacts, it is compatible with a wide range of vintage and modern manual lenses and is maintenance-light and straightforward to use.

Suitable for (tasks / use cases)

• Photographers adapting vintage or specialty manual lenses to Canon EF bodies
• Videographers who prefer manual focus and aperture control for cinematic workflow
• Creative projects requiring unusual optical rendering from legacy glass
• Still-life, portrait and experimental photography using third‑party lenses

Key specifications

• Mount type: input mount to fit manual lenses (manufacturer-specific) to Canon EF output mount
• Connection: fully mechanical, no electronic communication
• Control: preserves manual focus and manual aperture control on the lens
• Compatibility: designed for physical adaptation of manual-focus lenses to Canon EF-mount cameras
• Build: metal and/or high-strength materials for secure attachment and repeatable mounting

How to use

Attach the manual lens to the adapter by aligning the lens mount index and rotating until it locks, then align the adapter to the Canon EF socket on the camera and rotate until the adapter clicks into place. Use the lens focus and aperture rings to set focus and exposure manually; confirm focus with the camera’s viewfinder, live view, or focus peaking if the camera supports it. Remove the adapter and lens by reversing the procedure: press the lens release on the camera and rotate the adapter to detach from the body, then unlock and remove the lens from the adapter.

Usage recommendations

Check mechanical fit and mount alignment before mounting expensive or heavy lenses. Use a lens support or tripod collar for long or heavy lenses to avoid strain on the camera mount. When shooting without electronic aperture control, expose using manual camera modes or use the lens aperture ring and adjust ISO/shutter speed as needed. For critical focus, prefer live view with magnification or cameras with focus peaking enabled.
