Blackmagic URSA Mini Pro Shim Kit

URSA Mini Pro Shim Kit is a set of nine precision shims and a dedicated baffle tool for making exact changes to the flange focal distance of a URSA Mini Pro's EF, PL or B4 mount. Shims range from 0.025mm up to 0.5mm so a technician can correct back-focus in fine steps.

Proper shimming keeps lenses hitting true infinity focus and holding consistent sharpness across the focus range, especially with cinema glass shot wide open. Blackmagic part number BMD-CINEURSAMUPROSHM.
