Blackmagic URSA Mini B4 Lens Mount

The Blackmagic URSA Mini B4 Mount is an accessory for URSA Mini PL models that lets you swap the built in PL lens mount on your URSA Mini with a B4 lens mount. Featuring precision glass optics, the B4 mount is specifically designed to match URSA Mini’s sensor with high definition B4 lenses. The mount also has spherical aberration correction so lenses can be used wide open with no blooming effect. B4 lenses can be fully electronically controlled from the URSA Mini PL lens control connection.

If you already have an investment in incredible high definition B4 lenses, now you can use them with URSA Mini PL by adding the optional B4 lens mount. Unlike lens adapters, you can actually replace the lens mount itself to get a B4 mount with precision optics and spherical aberration correction specifically designed to match URSA Mini’s sensor! The B4 mount turns your URSA Mini into an incredibly compact HD camera with better dynamic range and support for more modern file formats than any other broadcast camera! The built in lens control connection provides power, start/stop recording and lens control for the lens. With the Blackmagic URSA Mini B4 Mount you can easily move between B4 and PL lenses any time you need.
