## Long description

The KiwiFotos KF4165 adapter bagnetowy converts Canon EF lenses for use on Canon RF mirrorless camera bodies, preserving mechanical coupling and correct flange focal distance to allow infinity focus. This adapter is a passive mechanical solution that enables photographers and videographers to mount existing EF and EF-S optics on RF-mount mirrorless bodies while maintaining secure attachment and reliable alignment.
Advantages
The adapter provides a durable metal-to-metal fit between EF lenses and RF mounts, ensuring consistent lens positioning and mechanical stability. By maintaining the correct flange distance it keeps infinity focus and accurate optical centering for stills and video. The passive design does not introduce additional optics, preserving the original lens characteristics, sharpness, and focal length. Its compact profile adds minimal extension to the lens system, keeping balance and handling predictable on both full-frame and APS-C RF bodies.
Suitable for
 Photographers who want to use Canon EF/EF-S lenses on Canon RF mirrorless bodies
 Videographers adapting EF cinema or DSLR lenses for RF-mount video rigs
 Owners of legacy EF glass who need a cost-effective mounting solution
 Hybrid shooters switching between DSLR and mirrorless systems
Key specifications
 Mount conversion: Canon EF/EF-S to Canon RF
 Type: mechanical (passive) adapter without optical elements
 Material: metal construction for mount surfaces and body
 Maintains correct flange focal distance for infinity focus
 Compact profile to minimize extension of the lens assembly
How to use
Attach the adapter to your Canon RF camera body by aligning the mounting indexes and turning until it locks into place. Mount your Canon EF or EF-S lens onto the adapter in the same manner as attaching to an EF camera, ensuring the lens locks securely. Because the adapter is mechanical and passive, electronic communication between lens and camera (autofocus, aperture control, EXIF) may not be supported; check camera and lens compatibility before use. To remove, press the camera’s mount release and rotate the adapter or lens as appropriate.
Usage recommendations
For stable handling, use lenses with tripod collars on long telephoto optics when mounted with the adapter. Verify focus and exposure settings manually if electronic control is limited and consider using manual focus or focus assist functions on the RF body for critical work.
