Product Overview +

Bridging B4 Optics with Modern XDCAM Sensors

The Sony LA-EB1 Mount Adaptor is a strategic tool designed to expand the lens compatibility of the PXW-FX9, PXW-FS7, and PXW-FS7 II. By allowing these large-sensor cameras to utilize B4 lenses, broadcasters can achieve the deep depth of field and high-power zoom capabilities essential for fast-paced news and documentary applications. This adaptor allows production houses to maximize their existing B4 lens assets while benefiting from the advanced features of modern XDCAM bodies.

Seamless Broadcast Operational Workflow

When used with an appropriate DC supply (such as the XDCA-FX9 or XDCA-FS7 extension units), the LA-EB1 offers a fully integrated experience. It supports the lens communication interface, allowing the camera's REC button and servo zoom to function natively with the B4 lens. This setup provides a familiar, ergonomic feel for operators transitioning from standard broadcast cameras to digital cinema-style bodies in Pakistan, the UAE, and Africa.
