Viltrox speed booster 0.71x EF-E II (Canon EF > Sony E Autofocus)

The Viltrox EF-E II is an autofocus speed booster adapter that lets you use Canon EF mount lenses on Sony system cameras with an E mount and an APS-C sensor. It reduces the focal length: the effective focal length is 0.71 times the original and the lens becomes brighter and faster. When the lens and camera body are connected, autofocus and automatic aperture adjustment work.
