The Viltrox EF-NEX IV Autofocus Lens Mount Adapter is a powerful and professional solution for photographers and videographers who want to use their Canon EF and EF-S lenses on Sony E-mount mirrorless cameras. Designed with advanced electronics and precision engineering, this adapter allows seamless communication between your lens and camera, unlocking autofocus, aperture control, EXIF data, and stabilization just like native lenses.

Whether you are shooting with a Sony A7 series, A9, A6000 series, or FX cameras, the EF-NEX IV ensures fast, reliable performance for photography and video. It supports both CDAF (Contrast Detect Auto Focus) and PDAF (Phase Detect Auto Focus), enabling quick subject tracking, eye detection, and smooth focusing for moving subjects. This makes it ideal for portraits, weddings, wildlife, vlogging, and professional video production.

Unlike basic mechanical adapters, this Viltrox adapter includes a built-in electronic control system that allows you to change the lens aperture directly from your Sony camera body. EXIF data is also transmitted, so your camera records important shooting information like aperture, focal length, and ISO—essential for workflow, editing, and lens profiling.

The adapter is engineered with high-precision metal mounts for both the Canon EF lens side and Sony E-mount camera side, ensuring a secure, wobble-free fit and perfect flange distance for accurate focusing. It also supports in-lens image stabilization (IS), helping to reduce blur and improve handheld shooting performance.

Firmware is USB upgradable, allowing Viltrox to improve compatibility with future Sony cameras and Canon lenses. This ensures long-term value and continued performance as your gear evolves.

If you already own Canon EF or EF-S lenses, the Viltrox EF-NEX IV is the most cost-effective way to use them on Sony mirrorless cameras without sacrificing performance. It turns your Sony E-mount camera into a flexible hybrid system capable of working with a massive range of professional Canon lenses.
