This Lens Mount Adapter from Rayqual allows you to mount a Leica VISOFLEX II/III lens on your Nikon Z-mount camera (VISOFLEX I lenses require an additional adapter). It supports manual focusing in both manual and aperture priority modes. Autofocus is not supported, but the adapter does allow you to use depth of field preview and stopped down metering if your camera and lens support it. Constructed with precision in mind, the flange depth has been tested with a variety of camera bodies and lenses to deliver exacting performance and maintain infinity focus. Please note that when using In-Body Image Stabilization (IBIS), the focal length should be set in the camera. Made in Japan, the adapter was designed and manufactured to maintain a parallel optical pathway while eliminating internal reflections.
