The Chinese accessory and optics manufacturer Viltrox has announced a new Canon EF  to Sony E-mount lens adapter with a built-in OLED display, full autofocus support, and EXIF data transfer capabilities.

The new adapter is the 5th model of Viltrox Canon to Sony adapters in a series that goes back to the original adapter that made Canon EF lenses usable on Sony NEX cameras. Viltrox says its latest version is the result of 9 years of continuous development since the Mark I version. The adapter supports full autofocus capabilities of EF lenses on Sony E-mount cameras, with a clever dial on the side of the adapter for switching between phase detection autofocus (PDAF) and contrast-detection autofocus (CDAF) modes.

The adapter will automatically transfer EXIF data from the lens to the camera, meaning aperture adjustments made on the camera should set the correct aperture on EF lenses with electronic aperture controls. The EXIF support also means IBIS is supported with compatible Sony E-mount cameras.

There’s also manual aperture control through the adapter that can be controlled with the + and – buttons on the side to the left of the screen. Holding the + button down brings the adapter into and out of manual aperture mode, and pressing the + and – buttons allows the aperture value to be adjusted while in manual mode. Inside the front mount of the adapter is a Micro USB port that is used to perform firmware updates. Viltrox says that updates will allow the adapter to be upgraded to be compatible with future cameras and lenses on the market.
