The Autofocus Speed Booster EF-Z2 adapter from Viltrox allows the use of Canon EF lenses on Nikon Z camera bodies. It includes a 0.71x optical multiplier, while the electronic contacts are gold-plated with pure copper. Electronic communication between the camera and lens is supported, allowing for autofocus. With some lenses, the maximum focal distance may be affected as the distance from the lens to the camera sensor changes slightly. There is an increase of one stop in the camera's focus compared to the lens's range. Full-frame cameras function only in APS-C mode.

Some features of specific lenses may not be fully available depending on the camera body. A USB port is available for firmware upgrades, and there is a 1/4"-20 tripod socket at the bottom of the adapter.
