Ommlite Autofocus Adapter EF-EOSM Booster

This is an electronic mount adapter for attaching Canon EF mount lenses to Canon EF-M mount cameras. The built-in focal reducer (reducing optical system) lens is composed of 5 elements in 4 groups of high-quality lenses, reducing the focal length of the attached lens by 0.71x, allowing for wider angle shooting. Additionally, the light-gathering effect of the focal reducer lens makes the F-stop one stop brighter.
