About Sony B4

The Sony FZ to B4 2/3" Lens Adapter 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.

The adapter allows your camera to display lens data information, such as focus, zoom and iris in the viewfinder. The adapter supports chromatic aberration compensation using ALAC-2 for select lenses and you can assign the "RET" button allowing you to call functions such as Expanded Focus and last clip review. The LA-FZB2 includes 15mm rods, lens support bracket and lens support knob.
