Kinefinity EF 3 Mounting Adapter w/ KineEnhancer

The Kinefinity A230-002-01 EF 3 Mounting Adapter w/ KineEnhancer is a 200 g active EF-to-KineMOUNT adapter that embeds a 0.72× optical focal reducer, boosting aperture by +1 stop, widening field of view, and converting full-frame EF glass to S35 coverage with full electronic iris/AF/IS control and tool-free hot-swap.

The A230-002-01 EF 3 w/ KineEnhancer is Kinefinity’s ultimate EF upgrade: a precision tele-compressor built into an active EF adapter that turns any MAVO Edge 8K/6K, MAVO mark2, or TERRA 4K into a full-frame. The multi-coated 0.72× optics deliver a true +1 stop light gain (T1.4 → T1.0), 28% wider FOV, and S35-optimized image circle with edge-to-edge sharpness and minimal chromatic aberration. Gold-plated contacts pass iris, AF, IS, and EXIF while the dual-lock bayonet ensures zero play and hot-swapping under power. A 0.8-mod iris gear works with any follow-focus. Factory-calibrated on KineMOUNT, it weighs just 200 g perfect for pairing Canon CN-E primes or Sigma 18-35 T2 with TERRA 4K for large-S35 punch or MAVO 6K for near-full-frame glory.
