Viltrox EF-Z2 Autofocus Speed Booster Adapter for Canon EF Lens to Nikon Z Camera

This EF-Z2 Autofocus Speed Booster Adapter from Viltrox allows a Canon EF lens to be used on a Nikon Z camera body. A 0.71x optical multiplier is built into the unit, and the electronic contacts are gilded with pure copper. Electronic communication between the camera and lens is supported, enabling autofocus. With some lenses, maximum focusing range maybe affected as the distance from the lens to the camera's sensor is slightly changed, and there is a 1-stop increase for the camera over the lens's aperture range.
At the Full frame cameras work only to APS-C mode.
Additionally, the functions of some lenses are not fully available depending on the camera body. A USB Port is provided for firmware upgrades, and a 1/4"-20 tripod socket on the bottom of the adapter allows for tripod mounting.
