Viltrox Speed Booster 0.71x AF Canon EF Lens to EOS M Camera EF-EOS M2

This 0.71x Lens Mount Adapter from Viltrox allows a full-frame Canon EF-mount lens to be mounted onto a Canon EF-M-mount camera. While doing so, the adapter's optics help to maximize the connected lens's apparent angle of view while providing a one-stop increase for the camera over the lens's aperture range.

If a lens intended for 35mm film or similarly-sized full-frame camera sensors is connected to a Canon EF-M-mount camera, this adapter condenses the light from a lens designed for 35mm film or "full frame" camera sensors and projects it onto a Canon EF-M-mount camera's APS-C sensor. This allows the APS-C sensor to utilize more of the light gathered by a connected lens, which effectively reduces the crop factor while making available to the sensor an additional one stop of light for each of the lens's f/stop settings.

VILTROX EF-EOS M2 mount adapter is designed to allow Canon EF-mount series lenses to be used on interchangeable-lens digital cameras that are compatible with EF-M lenses.

Focal length is multiplied by 0.71x based on the original (equivalent focal length = focal length x 0.71), giving 1-stop larger aperture and increased sharpness.

Supports auto focus, aperture control, lens Image Stabilisation & EXIF data transmission.

Built-in USB port for future firmware upgrades.

Gold-plated electrical contacts to enhance transmission performance;

The ring at the bottom with 1/4 screws, which can easy installed on the tripod or other fixed bracket.
