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.

A Built-In OLED Screen

The new adapter (first spotted by DPReview) features a built-in OLED display that allows the user to easily see current settings, including focal length, aperture, and focus mode.

The adapter supports both phase-detection and contrast-detection autofocus, and the mode will be indicated by either a P or a C (respectively) on the adapter screen. The focus mode is selected using a dial to the right of the screen.

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.

Holding down the button causes the adapter to enter object distance display mode, showing the distance of what the camera is pointed at.

Adapter Upgrades Through USB

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.
