If you want to use your existing PL mount lenses on a camera with a Sony E-mount, you need an adapter. The Metabones MB_PL-E-BT1 PL to E-Mount Adapter with Internal Flocking mounts to your camera’s lens port and allows you to use PL mount lenses with your camera. Although this is not a permanent conversion, the adapter features a removable support foot to take the strain off of your camera’s mount.
