This black EF-E II Lens Adapter from Yougnuo allows a Canon EF or EF-S mount lens to be used on a Sony E-mount camera. Electronic communication between an attached camera and lens is supported, which enables autofocus, image stabilization, as well as camera-controlled aperture functions. If an attached lens is also capable of generating Exif metadata when used with a directly compatible camera, this lens adapter is designed to allow that information to be saved along with image files.

When using a compatible Sony E-mount camera, its Custom Key Settings menu can be used to associate a user-selectable command to the adapter's built-in custom function button.

Within the adapter barrel, an internal, matte black covering minimizes the appearance of reflections. To help reduce stress on the camera mount when placed on a tripod, the adapter includes an Arca-type compatible tripod foot with 1/4"-20 threads.
