The Blackmagic Design B4 Mount Body Cap is a genuine replacement dust cover for Blackmagic broadcast and cinema cameras equipped with a B4 lens mount. Designed to seal the camera's mount opening whenever a lens is removed, it shields the imaging sensor, optical block, and internal electronics from dust, debris, and accidental contact during transport, storage, and lens changes on set. As an original Blackmagic accessory, it provides an exact fit that aftermarket covers cannot reliably guarantee.

This single-piece cap directly replaces the body cap originally supplied with Blackmagic Design Cinema Camera, Production Camera 4K, and URSA models configured with the B4 mount, making it an ideal spare or replacement for crews that swap mounts and lenses frequently. Its lightweight, low-profile black construction keeps it easy to stow in a camera bag or pelican case, so a protective cover is always on hand when the camera is parked between shots.

For broadcast and ENG operators running B4 ENG-style optics, keeping the sensor cavity covered is essential to preventing costly cleaning and downtime. This Blackmagic B4 body cap delivers that protection in a simple, purpose-built accessory backed by the Blackmagic Design name.
