The 2017 Blackmagic URSA Mini Pro added broadcast-style external controls, built-in ND filters and an interchangeable lens mount to the URSA Mini 4.6K, creating the line's first true production camera.
It records 4.6K RAW and ProRes to dual CFast or SD, with 15 stops of dynamic range, a swappable EF/PL/B4 mount system, and dedicated switches for ISO, shutter and white balance.
Its significance is versatility: one body served single-operator documentary and full broadcast rigs, and the G2 that followed in 2019 kept the same shell - used listings frequently omit the generation.
A listing saying 'URSA Mini Pro' or '4.6K' without G2 is this first generation; G2 adds 300fps and USB-C recording and holds noticeably higher prices. Check ND wheel operation, mount screws, and CFast slot health.
