Kinefinity EF Adapter 3 Combo

The Kinefinity A923-001-01 EF Adapter 3 Combo is a triple-threat lens mounting system for MAVO Edge and TERRA cameras, bundling the standard EF 3 active adapter, EF 3 w/e-ND (motorized 0.6–2.1 ND), and EF 3 w/KineEnhancer (0.72× focal reducer +1 stop) in one kit—delivering tool-free lens swaps, full electronic iris/AF, and exposure/optical flexibility in a 200 g aluminum package.

The Kinefinity A923-001-01 EF Adapter 3 Combo gives MAVO Edge 8K/6K, MAVO mark2, and TERRA cameras three active EF adapters in one box. All share the patented dual-lock system: clockwise DSLR-style rotation to seat, then a final 15° active lock for zero play. Gold-plated contacts transmit iris, AF, IS, and EXIF for Canon CN-E, Sigma ART, and Tamron lenses. The e-ND version embeds a liquid-crystal ND (0.6–2.1, 2–7 stops) with auto color calibration—no matte box, no gel filters. The KineEnhancer version adds a 0.72× tele-compressor, turning full-frame EF glass into S35 coverage with +1 stop light gain and sharper corners. Each adapter weighs 200 g, installs tool-free on KineMOUNT, and supports hot-swapping under power.
