EF Lens Communication with C300 Mark II

The more than one hundred standard Canon EF lenses have a direct electronic communication
with the C300 Mark II camera.

Figure 16

The standard EF L series lenses (shown mounted on the C300 Mark II) have full

electronic communication with the camera. The EF versions of the CINE-SERVO lenses (shown on the
left) are also planned to communicate with the camera

A planned firmware upgrade to the CN7x17 CINE-SERVO lens will allow many of the functions
of this lens to be used by the C300 Mark II. These will include:

  Remote control (through the camera) of Zoom, Focus, and Iris
  Chromatic aberration correction  (per planned future firmware update to C300 Mark II)
  Selectable T-No / F-No view availability
  Peripheral illumination correction (per planned future firmware update to C300 Mark II)
  Lens Metadata recording
  REC Start / Stop from the lens drive unit

It is also planned to have a downstream firmware upgrade for the CN20x50 CINE-SERVO lens.
