Despite having a delay in shipping its anticipated MAVO Edge 8K cinema camera (now expected by February), Kinefinity has released a new EF mounting adapter for its MAVO LF/6K and TERRA cameras.
The EF 3 Mounting Adapter is based on the EF Mounting Adapter II but literally adds a new twist. When using the EF Mounting Adapter II, you wouldn't rotate the EF lens as you would on a traditional DSLR or mirrorless camera to secure it. Instead, you would hold the lens in place while rotating a locking ring to mount the lens to the camera. This is similar to mounting PL lenses.
The EF 3 is redesigned to simplify the process with a bayonet style mount. Users can now mount a lens as they normally would on a Canon camera by lining up the red dots and then rotating the lens clockwise. The EF 3 has an additional active lock to fully secure the lens. This is a nice improvement from Kinefinity as it adds confidence when lining up the communication pins between the lens and mount.
