EF Mounting Adapter II w/ KineEnhancer


It fits: [MAVO and TERRA].

KineEnhancer as a highly accurate optic glass, built-in mounting adapter. It brings wider angle and one more stop on max aperture.

Cordless, lightweight and electronic protection are the main features making the new adapter superior than the previous versions.

EF mounting adapter with KineEnhancer has three big advantages over traditional mount: (Please visit and buy the Regular EF adapter II if you don’t need focal reducer)

Perfect creation with Enhanced performance by KineEnhancer

KineEnhancer as a highly accurate optic glass, built-in mounting adapter. It brings wider angle and one more stop on max aperture. The features of KineEnhancer based on optical precision include:

  1. Focal reducing factor as: 0.72, compared to normal S35 shooting;
  2. Increase maximum aperture up to: 1 stop;
  3. Crop factor to: 1.1 when using on MAVO 6K;
  4. Crop factor to: 1.3 when using on TERRA 4K;
  5. Very good performance on edge and colour fringing.

Cine-Style Mount

From 2014 Jan, every mounting adapter employs whole new lock-type mount. Its fixing way is very similar to Cine PL mount: lock ring rotation, not lens rotation to make sure lens locked firmly in any case. Compared to traditional lock way based on metal spring, the new EF mount gains much better stability; fits very well in professional way when video shots using follow-focus gear.

Iris Controlled in Camera
The cine mount can control the iris of EF lens electronically, if the EF lens is in the EF compatible list: EF lens compatibility.

Its features cover following:

  1. Built-in glass as KineEnhancer;
  2. New lock type mounting system: enhance mechanical performance greatly;
  3. Iris-tuneable for compatible EF lens;
  4. Interchangeable Mounting adapter for KineMOUNT; Quick and Robust for mount change.
  5. Reliable and robust, mixture of aero Aluminum Alloy, steel and golden contact.


  • EF-S lens can not installed to the mount with KineEnhancer, because the rear end of EF-S lens is longer than EF lens;
  • Power down camera when swapping different adapters, else camera or adapters may be burned. 

FAQ for EF Mounting Adapter II

Yes, if the adapter is regular EF mounting adapter.

No, if the adapter is KineEnhanced embedded.

No, if the adapter is regular mounting adapter, since MAVO 6K/TERRA 4K configs with S35 or sub-S35 CMOS sensor.

Yes, if you choose the adapter with KineEnhancer.

It supports ZE lenses, also new Milvus lenses.

Please refer to EF Lens Compatible White-List: EF lens compatibility

No, the Mounting Adapter II has circuit protection.

Note: FFD of KineMOUNT is very short, and the mount looks like PL mount. NEVER try to attach any lens into the KineMOUNT directly, in case the rear of lens bump into the CMOS sensor, which leads to permanent damage.

    1. Power down: Power down camera at first when remove or install any mounting adapters;
    2. Release: Rotate the locking ring of KineMOUNT in Counter-Clockwise way;
    3. Install the adapter to KineMOUNT: when attaching the mounting adaptor to KineMOUNT, please ensure the two holes in the adaptor match the two pins of KineMOUNT;
    4. Lock: Rotate the locking ring of KineMOUNT to fasten adapter with KineMOUNT firmly in Clockwise way.Power on camera after mount the adapter. Press “CONFIG” and check the bottom of this menu, if it presents EF sys 9(or other number), it means you have mounted the adapter successfully.

Not so far.

For camera mounted with compatible lens, rotate the Multifunction Wheel to adjust the iris. If camera is equipped with SideGrip, the Multifunction Wheel on the SideGrip can also be used to control iris.
