Compatibility Information

This adapter is designed for use with APS-C and Super 35 sensor cameras, including popular models such as Canon EOS 7D, Canon C300, Blackmagic Cinema Camera EF and Blackmagic Production Camera 4K. When used with a Canon EOS-1D C, the camera must be set to Video Mode with Super 35 crop enabled.

For optimum results, the adapter should only be used with B4 2/3" broadcast lenses featuring an integrated 2x extender engaged. HD broadcast lenses are strongly recommended to achieve the highest image quality and resolution across modern digital cinema sensors.

Whether you're repurposing professional ENG lenses or expanding your filmmaking toolkit, this B4 to Canon EF adapter provides a cost-effective solution for integrating broadcast optics into your EF-mount workflow.
