Sony LA-FZB2 B4 Lens to FZ Mount Adapter for F5 & F55

The Sony LA-FZB2 B4 Lens to FZ Mount Adapter for F5 & F55 allows you to mount most 2/3" prism block B4-mount lenses to a Sony F5/F55 single sensor camera, while maintaining the same angle of view the lens exhibits on a 2/3" prism block camera. The adapter provides the communication between the lens and the camera, passing metadata, while providing servo control of the adapter's built-in CC and ND filters.
