Canon Just Made a Big Video Improvement to the 5D Mark IV

Canon’s 5D Mark IV is a very well-rounded DSLR, but when it was announced last year, many filmmakers were upset that a few critical video features were missing.

Chief among them was a log format to capture more dynamic range from the camera’s sensor. Today, Canon announced that it will indeed offer a Log option in a firmware upgrade due in July. Unfortunately, it will cost you $99 to have it installed and it will require having the camera shipped to a Canon Factory Service Center. All new 5D Mark IVs sold from July forward will have the log option baked in.

According to Canon, the new Canon Log profile offers suppressed contrast and sharpness and increased dynamic range of up to 800 percent or 12 stops (at ISO 400 or above). A View Assist setting will enable you to preview your scene with contrast and sharpness added back in.

The Canon Log will also include two Look Up Tables (LUTs) that correct the recorded image’s gamma and color space when viewed on an external monitor. According to Canon, in the Log 10 to Wide DR LUT, the video file is converted to Wide Dynamic Range gamma, with well-preserved highlights and shadow detail; while the Canon Log 10 to ITU-R BT.709 LUT converts a file to ITU-R BT.709, providing conventional camcorder specs for viewing in a color space consistent with an HDTV.
