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.
The adapter features internal flocking to reduce internal reflections, Chromium-plated brass front and rear contact surfaces for corrosion resistance. The hard front and rear contact surfaces serve to maintain the adapter's tight tolerances over time, ensuring the correct flange focal distance. This is a mechanical adapter that does not pass any electronic lens control or metadata.
