It has been officially confirmed by Canon that the long-awaited C-Log functionality finally comes to the Canon 5D Mark IV. Unfortunately, this will be a paid upgrade costing $99, and in order to get it, you’ll need to send your camera to a Canon service center first.
The paid upgrade will be available as of July 2017. It’s also expected that the new batch of cameras with the Canon Log pre-installed on board should also start shipping in July with an estimated retail price of $3,599. The upgrade should enable the EOS 5D Mark IV to achieve a similar look to that of the Cinema EOS cameras.
According to Canon, all 4K and Full HD video files captured while using the Canon Log feature should theoretically increase the available dynamic range of the camera up to 12 stops when shooting at ISO 400 or above. This means more detail in the highlights, enhanced details in the shadows, and more overall flexibility to work with in post. The upgrade will also include a View Assist setting that provides a preview on the LCD monitor of how an image may look with post-processing characteristics.
In addition, the Canon Log feature includes two Look Up Tables (LUTs) that correct the recorded image’s gamma and color space when viewed on an external monitor. With Canon Log 10 to Wide DR LUT, the video file can be converted to Wide Dynamic Range gamma, with well-preserved highlights and shadow detail. With Canon Log 10 to ITU-R BT.709 LUT, the video can be converted to ITU-R BT.709, providing conventional camcorder specs for viewing in a color space consistent with an HDTV.
Beyond any doubt, this is a huge announcement for Canon and a fantastic addition to the camera itself alongside other appealing features that it already provides such as the 30.4 Megapixel Full-Frame CMOS sensor with DIGIC 6+ processing, Dual-Pixel AF, and of course, the long-awaited 4K DCI video recording.
