The Lens Mount Adapter for Canon EF/EF-S Mount Lens to Sony NEX Camera from Dot Line allows you to use your collection of Canon DSLR lenses with the mirrorless NEX camera body. It will maintain automatic focusing and metering capabilities and features a removable tripod mount for stability and security when using larger lenses. The adapter will fit physcially, but is not fully functional with Sony E-mount full frame cameras
