Kinefinity EF Adapter 3 Combo

The Kinefinity EF Adapter 3 Combo is an EF mount adapter with a built-in electronic ND filter, built for MAVO and TERRA shooters who want the familiar DSLR-style lens rotation of an EF mount combined with the locking security of a PL mount. It keeps the traditional clockwise EF lens rotation while adding an active lock that fastens the lens firmly in place, so it stays put during Follow Focus work the way a PL lens would. Like Kinefinity's PL adapter, its e-ND covers 2 to 7 stops in one seamless adjustment, without carrying a set of glass ND filters.

• Locking EF mount: Uses the traditional clockwise EF lens rotation but adds an active lock that fastens the lens firmly without play, suited to Follow Focus use.
• Built-in electronic ND: A liquid-crystal e-ND covers 0.6 to 2.1 (2 to 7 stops) in one continuous adjustment, without swapping glass filters.
• Iris control support: Supports iris control on the majority of EF lenses through the adapter's electronic contacts.
• Fast lens changes: The active locking design allows lenses to be installed and locked quickly, similar to swapping a PL lens.
• Lightweight build: Kept lightweight and compact despite the added electronics, matching Kinefinity's MAVO/TERRA mount ecosystem.
• Includes a standard EF adapter: The combo bundles both the e-ND-equipped adapter and a regular EF mounting adapter for jobs that don't need variable ND.
