The Blackmagic Design CINEURVPLSHIM is an URSA PL Mount shim kit. This kit ships with 8 shims which can be used to change the flange focal distance for PL lenses.
The Blackmagic URSA is the world’s first high end digital film camera designed to revolutionize workflow on set. Built to handle the ergonomics of large film crews as well as single person use, URSA has everything built in, including a massive 10 inch fold out on set monitor, a new user upgradeable 4.6K Super 35 image sensor with a massive 15 stops of dynamic range, 12G-SDI, internal dual RAW and ProRes recorders and more. Because the sensor and lens mount assembly can be changed, you can upgrade to the latest sensor technology in the future and keep your investment in the camera body!
