Operating Instructions

The VILTROX EF-M1 adapter allows your Canon EF/EF-S lenses to function effectively on M4/3 cameras. Here's how to operate its key features:

Autofocus Function

Once the adapter and lens are securely mounted, the camera's autofocus system will communicate with the lens through the adapter's electronic contacts. Ensure your camera's autofocus mode is set appropriately (e.g., AF-S, AF-C, MF) for your shooting needs. The adapter is designed to provide fast and accurate autofocus performance.

Aperture Control

The adapter's built-in aperture motor and electronic contacts allow you to control the lens aperture directly from your M4/3 camera body. Adjust the aperture settings on your camera as you normally would, and the adapter will transmit these commands to the attached Canon lens.

EXIF Information Transmission

The VILTROX EF-M1 supports EXIF signal transmission, meaning your camera will display and record essential lens information. After installing the lens, you can view details such as the current aperture, shutter speed, and ISO settings directly on your camera's display or in the image metadata.
