Make full use of your existing Canon EF and EF-S-mount lenses on your Sony E-mount mirrorless camera with this Pro Fusion Plus Smart AF Adapter from Fotodiox. Featuring FUSION technology, this intelligent adapter features electronic contacts that fully maintain autofocus, auto-exposure, and image stabilization capabilities as well as transfer Exif data and enable aperture adjustment from the camera body. Also, an AF Mode toggle switch can be used to set the adapter to respond to either contrast-detection or phase-detection autofocus, depending on the mode the camera supports. The Plus version of this adapter further adds a micro-USB port to the design, which is used to update the adapter's firmware for future lens support and bug fixes. Complementing the electronic sophistication, this adapter is also characterized by its durable chrome-plated brass construction and removable 1/4"-20 tripod mount to help support heavier lenses.
