Make full use of your existing Canon EF and EF-S mount lenses on your full-frame or APS-C Sony E-mount mirrorless camera with this Pro Fusion Smart AF Adapter from Fotodiox. Featuring electronic contacts and communication, this adapter enables autofocus and auto exposure with adapted lenses. All image stabilization functionality is retained as well, and it permits adjustment of the aperture from the camera controls. An added feature is the transmission of Exif data to the camera for users to review information later. The adapter will guarantee infinity focus and it features a removable tripod foot with a 1/4"-20 socket. Additionally, it is constructed from brass with a stainless-steel finish. Due to differences in camera design and lens firmware, not all functionality is possible with every combination of lens and camera. This adapter only officially supports Canon lenses introduced in 2006 and later, with older lenses not guaranteed to work.
