Canon C300 Gets Push To Focus Update

April 4, 20132 Comments

When I read this today I got very excited. The push to focus feature is great on the C100 and Canons reason for not including it on the C300 was that filmmakers don’t need auto focus. Well, we do sometimes and if a lens has the function then let use decided if we want to use. Great job Canon for giving the C300 this option.

Another cool update is Shifting Display Location during Magnified Focus Assist. I can use this when slip focusing from off center subjects. Had to do this today and it would have been great if I had it.

The firmware upgrade also adds for the Cinema EOS C300 and Cinema EOS C300 PL Digital Cameras a 1,440 x 1,080 pixel recording mode at 35Mbps. A little smaller file but maintaining a high level of image quality. Similar to AVCIntra 50.

The update wont be available until October 2013. That’s a little disappointing but these are very good firmware updates and I cant wait to install them. From what I understand Canon is a little slow to add features via firmware updates so maybe we will see a few more sooner than later.

Canon U.S.A. Announces Free Firmware And Application Software Upgrades For Select Cinema EOS System Cameras

New Upgrades, Including Support for Industry-Standard ACES, Look to Help Deliver Greater Production Workflow Efficiency

MELVILLE, N.Y., April 3, 2013 – Canon U.S.A., Inc. a leader in digital imaging solutions, announced today new firmware and application software upgrades for the Company’s Cinema EOS System lineup of cameras. New ACES compatibility software for the Cinema EOS C500 and Cinema EOS C500 PL Digital Cameras will be available as a free download expected in June 2013. Additional Cinema EOS firmware upgrades, including a new 1,440 x 1,080 pixel recording mode at 35Mbps for the Cinema EOS C300 and Cinema EOS C300 PL Digital Cameras, are expected to be available as free downloads starting in October 2013, all from


In response to strong demand from professionals working in the fields of motion picture, commercial and television production, the firmware and application software upgrades will offer enhanced color management efficiency and camera functionality, contributing to improved video production workflow efficiency.

ACES Compatibility for Greater Production Workflow Efficiency (EOS C500/EOS C500 PL)

Cinema EOS C500 and Cinema EOS C500 PL camera users will be able to download a new version of Canon’s Cinema RAW Development Software for working with 4K RAW data. The new version provides support for the Academy Color Encoding System (ACES) color management standard, as defined by the Academy of Motion Picture Arts and Sciences (AMPAS) and standardized by the Society of Motion Picture & Television Engineers (SMPTE). Compatibility with ACES helps make efficient workflows possible, enabling color management using a uniform color space – even when handling video captured using multiple cameras with different color characteristics.

Automatic Functions (EOS C300) and New Recording Mode (EOS C300/EOS C300 PL)

A new firmware upgrade for the Cinema EOS C300 Digital Camera adds Push Auto Iris and One-Shot Autofocus (AF), two outstanding automatic functions incorporated in the Cinema EOS C100 Digital Camera (released in November 2012). These functions enable users to automatically adjust lens aperture and focusing through a simple one-touch operation, which can be particularly useful for cinematographers and videographers shooting without the support of an assistant.

In addition, a firmware upgrade for the Cinema EOS C300 and Cinema EOS C300 PL Digital Cameras adds a 1,440 x 1,080 pixel recording mode at 35Mbps, a resolution widely used in terrestrial digital television broadcasting. This new mode will expand the versatility of the XF codec and can be a useful addition for broadcast applications where the reduced bandwidth requires less transmission time while still maintaining a high level of image quality.

Shifting Display Location during Magnified Focus Assist (EOS C100, EOS C300/EOS C300 PL, EOS C500/EOS C500 PL)

Firmware upgrades for the EOS C500 and EOS C500 PL, EOS C300, EOS C300 PL, and EOS C100 Digital Camera models enable the Magnified Focus Assist function’s magnified view area within the viewfinder and LCD monitor to be shifted to locations other than the center of the screen, allowing users to confirm focus across the entire display area.

About ACES

Professionals in the cinema, television and other high-quality digital production industries commonly make use of multiple cameras when shooting video. As these cameras employ different sensors, each offers varying color characteristics. In addition, users can select from a diverse range of camera settings during image capture, such as aperture, focus position, frame rate and recording format, and because of this, images shot for a single scene can produce different results in terms of color and gradation, depending on the camera used.

Furthermore, when inputting, editing and outputting video, professionals may use various displays, each with its own color space, resulting in differences in how colors appear depending on the device used, even when viewing the same footage. For example, the viewfinder of a camera used during filming, the PC display used to edit the images, and the projector or television for viewing the video each offer varying color characteristics, causing the colors in the video to appear differently.

Therefore, color management takes a great deal of time and effort to correct for camera- and display monitor-related color differences.

ACES is a color management architecture developed by AMPAS, and standardized by SMPTE, that aims to improve efficiency among complex color management workflows by delivering uniform color expression through a standardized color space used during the video production workflow. Through compatibility with ACES, video captured using different cameras and settings can be aligned with the ACES color space, which offers a wide color range and high dynamic range. ACES provides an archive-ready file format, and also delivers high workflow efficiency by allowing users to confirm images with the same appearance even when using display devices with varying color characteristics during input and output.

  1. Hi Erik,
    Yes I heard about the C300 firmware upgrade today when I went by Abel Cine in NY to look at the C100. Hoping the jobs come through to rent those and move up from the AF-100 for handheld doc work.

    BTW when you fly with the Manfrotto rig, wondering how you manage focus in verite situations. Take your left hand off the wheel? I’ve been relying a lot on continuous AF with the GH-2 for those kinds of situations (with a cheap but good rig–the DSLR kit movie rig). Seems like the C100 is fine “as is” for a lot of handheld situations, but would also like to do the “semi-steadicam” thing too.

    Have fun at NAB

      Because the Fig Rig is so light I hold the grip on the C300 magnify and focus then grab the wheel. The camera stays in the same position so focus holds. This is for on-camera lines. Rouge would be tough. I sure could have used the push to focus feature this week. The rig gets my hands and arms out more so I can hold it better. I don’t as tired. I’m talking four hours of shooting with very little breaks.
