Commlite CM-EF-E HS Overview
This Lens Mount Adapter from Commlite 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, enabling autofocus as well as auto exposure features. If an attached lens is capable of generating Exif metadata, this adapter is designed to transfer that information so that it can be saved with image files generated by the combined Canon EF or EF-S mount lens and Sony E-mount camera. When used on a compatible camera, this adapter's integrated, phase and contrast detection toggle button provides the ability to quickly choose among either of those two autofocus systems.
Constructed from aluminum alloy, this adapter is durable while remaining lightweight. To help reduce stress on the camera mount when placed on a tripod, the adapter includes a detachable tripod foot with 1/4"-20 threads.
