The Vello Canon EF/EF-S Lens to Sony E-Mount Camera Adapter allows you to mount an EF/EF-S lens to a Sony E-mount (NEX or full-frame) camera body (except for PXW-FS7 XDCAM camcorder). The all-metal adapter is designed to fit the lens securely, yet can still be removed easily when not needed. A tripod collar with a 1/4"-20 mount enables you to shift the center of gravity for easier handling with heavy lenses, and relieve strain on the camera lens assembly.
Autofocus, automatic aperture and AE metering will be disabled by the lens adapter as there will be no electrical communication between camera body and lens. You will need to focus manually and set exposures manually or meter in aperture priority mode. The lens will retain its ability to focus to infinity.
