Viltrox EF-NEX IV Autofocus Adapter

Compatibility

The Viltrox EF-NEX IV adapter is designed to mount Canon EF and EF-S lenses onto Sony E-mount cameras and camcorders. It supports both full-frame and APS-C sensor formats, compatible with models such as:

• Sony A7 series
• Sony A9
• Sony A6000 series (A6000, A6300, A6400, A6500)

Features and Functionality

This adapter includes electronic contacts that enable communication between the lens and the camera body. It supports reliable autofocus operation, aperture control from the camera, and EXIF data transmission. A switch on the adapter allows selection between two autofocus modes:

• PDAF (Phase Detection Autofocus): Autofocus operates based on phase detection for faster focusing.
• CDAF (Contrast Detection Autofocus): Autofocus operates based on contrast measurement for precise focusing.

Construction and Materials

The adapter features a removable tripod foot with a 1/4-inch thread, allowing direct mounting of the lens on a tripod or quick release plate. It is constructed from high-quality aluminum, and the interior is blackened to prevent unwanted light reflections that could degrade image quality.
