Fotodiox has launched the Fotodiox Pro Fusion, a new super-thin autofocus adapter that allows photographers to utilize Sony E-mount lenses on Nikon Z-mount camera bodies. The term fusion refers to Fotodiox’s Fusion technology, which the company claims allows photographers to have complete access to aperture, autofocus, EXIF data, and all automatic and electrical functions of a lens to be sent and controlled by an attached camera.

“The Fusion technology built into the adapter enables electronic communication between mixed lens and camera platforms,” Fotodiox says. “Although the adapter will allow you to mount any Sony E-Mount lens, not all lenses will perform the same. Lens firmware, focusing motors, and age of lens will all affect the speed, reliability and accuracy of the adapter. The adapter draws the power it needs from the camera.”

The technology has already been employed in Fotodiox products, including a Canon EF to Nikon Z autofocus converter released two years ago. That converter, however, is significantly thicker than the new Sony E to Nikon Z Fusion adaptor, which is small enough to be almost imperceptible. This new adapter dubbed the “Fotodiox Pro Fusion Adapter, Smart AF Adapter,” offers a precise fit to both the camera body and attached lenses and boasts a strong all-metal construction with chrome-plated brass mounts, according to the company.

Furthermore, the company claims that the design has no plastic components and that the secure connection between an attached lens and the camera body will not deteriorate over time.
