Viltrox E-Z AF Lens Mount Adapter is an electronic adapter designed to use Sony E-mount lenses on Nikon Z mirrorless cameras. Its slim construction compensates for the flange distance difference between the two systems while maintaining electronic communication between the lens and camera body when the combination is compatible. The adapter supports autofocus, electronic aperture control, EXIF data transmission, and lens or in-body stabilization, allowing more complete integration than a simple mechanical adapter. It is compatible with several focusing modes, including AF-S, AF-C, and AF-F, and may support functions such as face recognition and Eye AF depending on the Nikon Z body, the lens used, and the installed firmware. Aperture adjustment can be performed from the camera body or from the lens, when supported by the lens. The Viltrox E-Z AF is intended for photographers and videographers who own Sony E or third-party E-mount lenses and want to use them on the Nikon Z system while retaining essential automation and shooting data. Operational performance may vary depending on the specific camera-lens combination, so it is advisable to check the compatibility list and keep the adapter firmware updated before professional use.
