Blackmagic Design BMD-CINEURSABMNTSHIMS URSA Cine Lens Mount Shim Set

The Blackmagic Design URSA Cine Mount Shims are an essential calibration accessory for cinematographers and camera technicians working with the URSA Cine. When critical lens-to-sensor alignment is required, stock flange focal distance settings may not account for variations across different lens mounts or optics. These shims attach directly to the lens mount and allow technicians to dial in exact tolerances without swapping hardware or sending the camera out for service.

Supplied in various thicknesses, the shims give operators the incremental control needed for demanding production environments where focus accuracy is non-negotiable. Whether preparing a camera package for a scripted feature, a broadcast production, or a high-end commercial shoot, having the correct flange focal distance eliminates back-focus issues at the source. This set is a practical addition to any URSA Cine kit maintained by a digital imaging technician or camera department that demands repeatable, verifiable lens performance.
