Viltrox EF-NEX IV Lens Mount Adapter Ring

The Viltrox EF-NEX IV Lens Mount Adapter Ring is an electronic lens adapter designed to mount Canon EF and EF-S mount lenses onto full-frame and APS-C Sony E-mount mirrorless camera bodies. Featuring gold-plated electronic contacts, it maintains full autofocus performance, aperture control, image stabilization (IS) support, and EXIF metadata transmission between the lens and camera body. A integrated mode switch allows users to toggle between Phase Detection Autofocus (PDAF) and Contrast Detection Autofocus (CDAF) to optimize focusing speed and accuracy depending on the camera body used. Built with a durable aluminum alloy barrel, it includes a removable tripod foot with a 1/4″-20 threaded socket to relieve stress on the camera mount when using larger lenses, alongside a micro-USB port for future firmware updates.
