Canon Expands Dual Pixel AF Upgrade to C300 Camera Users

By James DeRuvo (doddleNEWS)

Canon has announced that first generation Canon C300 will be able to add Dual Pixel CMOS Autofocus as a new feature. The update is a factory installed improvement, but with new firmware, it brings a long a host of other great features.

 The upgrade provides a new Continuous AF (Autofocus) Function for all Canon EF autofocus Lenses, using Dual Pixel CMOS AF technology. A new AF Lock setting also lets you change the image framing while holding the desired focus. These critical focusing capabilities are designed to help reduce out of focus video while providing for smooth focus transitions and assist users when operating with small crews. – Canon.com

Originally announced in 2014, the Dual Pixel CMOS AF upgrade program adds a new wrinkle aimed at smaller, one or two man crews looking to gain a leg up with autofocus expansion.

Dual Pixel AF works by two separate photodiodes interacting with one another, comparing their inputs during the AutoFocus mode. A phase difference between the two senses images indicate the focus is beginning to blur and  focus transitions occur more naturally, even when the camera is moving. The feature places higher priority on maintaining sharper focus with smoother transitions.

The Dual Pixel AF modification will also give the C300 a very large, centrally located autofocus zone, providing an increase the C300’s continuous autofocus function to 20% of the vertical image and 25% of the horizontal image. There is also an AF lock mode to enable the cameraman to set focus and hold it, even when adjusting the frame.

The result is smoother, more natural looking autofocus to the shooting of documentaries, corporate events, weddings and even live sports events.

In addition, with the aid of Contrast AF, the C300 will be able to detect a shift in contrast in the subject during movement, and adjust lenses in this initial direction to stay in focus, thereby reducing focus hunting. The upgrade also doubles the autofocus speed to make it look more natural looking without overshooting jerky focus movements.

Users who chose the hardware upgrade must first install firmware update 2.0.9.1.00. Be advised, however, once the camera is updated to the latest firmware version, it cannot be restored to a previous version.

But the benefits are multi fold as vs. 2.0.9.1.00 also brings its own set of new features and improvements to the mix:

With CN-E70-200mm T4.4 L IS KAS S lens attached the following features are enabled:

  1. Autofocus using the Dual Pixel CMOS AF function
  2. The joystick on the camera’s grip unit can be set to operate the zoom.
  3. Manual control of the iris with Camera’s Control dial.
  4. Control of focus, zoom and iris using the separately-sold Remote Controller RC-V100.
  5. Automatic aperture and push auto iris functions.
  6. Start/stop recording on the separately-sold lens grip ZSG-C10.
  7. Retrieval of Lens metadata, such as the model name and the focal distance will display on the camera.

When the camera is turned off the IS mechanical lock will be active regardless of the position of the switch.

The firmware update also adds peripheral illumination correction for the following lenses:

COMPACT-SERVO Lens

  • CN-E70-200mm T4.4 L IS KAS S

EF Lens

  • EF 70-300mm f/4-5.6 IS II USM
  • EF 16-35mm f/2.8L III USM
  • EF-S 18-55mm f/4-5.6 IS STM
  • EF-S 35mm f/2.8 Macro IS STM
  • EF 85mm f/1.4L IS USM

Note: If your camera’s firmware is already version 2.0.9.1.00, it is not necessary to update the firmware.  Users can download it here:
