Based on active locking mount as EF II series adapters, the updated EF Mounting Adapter Mark 3 with KineEnhancer from Kinefinity is designed in accordance with the traditional DSLR lens rotation method but with much improvement. With this adapter, the TERRA 4K turns into a Super 35 large-format camera (with crop factor 1.3x), and the MAVO 6K turns into a full-frame camera. The EF Mark 3 Mounting Adapter with KineEnhancer can also be used with the MAVO LF under Super 35 mode to shoot full-frame images, though there is vignetting under full-frame mode if used with this adapter.
Compared to the previous model, the EF Mounting Adapter Mark 3 with KineEnhancer not only uses the traditional way to rotate the lens clockwise, but it also keeps the active locking method to fasten the lens. This allows the EF lens to be installed quickly and locked clockwise as with a PL-mount lens, which is suitable for the use of a follow focus when shooting.
