A software upgrade for the Canon EOS 5D Mark IV adds Canon Log, which includes numerous advanced video features.
The “feature upgrade” allows the 5D to be used as a professional video camera, which Canon says provides a “cinematic look” similar to its Cinema EOS cameras. It’s important to note that this is only for the 5D Mark IV and is not compatible with previous models, and Canon isn’t calling this a firmware update because it is adding a specific feature and not addressing any operational issues with the camera.
Canon Log will be pre-installed on bodies, beginning in July. For those who want the feature earlier, it can be installed for US$99 at any U.S. Canon service center.
The 5D Mark IV uses a 30.4-MP full-frame CMOS sensor and has been available since September 2016. Out of the box, it can record 4K video.
Canon says Canon Log provides wider dynamic range and a larger number of choices for color grading, which allows for fine tuning of color saturation, color accuracy and more accurate skin tones.
Canon Log can work in conjunction with the 5D Mark IV’s other features, such as 4K video, Dual Pixel CMOS AF, high speed 119.9p shooting in HD and 59.94p shooting in Full HD.
Canon has set up a Web page (usa.canon.com/canonlog5d4) that explains all of the Canon Log features, as well as how to have this installed on your EOS 5D Mark IV.
Canon warns of horizontal stripes appearing in video recordings when Canon Log is turned on and explains what might cause this. Visit the link in the previous paragraph for more information.
