Through a chargeable upgrade service, the EOS 5D Mark IV has the ability to shoot in Canon Log. This is a movie mode which allows wider dynamic range and an expanded exposure latitude. When mixing several cameras together in a multi-cam shoot it makes it easier to match them up. When shooting Canon Log you may find there is some noise or horizontal banding stripes. If these are present, then firstly make sure Peripheral Illumination Correction is disabled and then shoot the movie at a brighter exposure setting as the noise will be visible in shadow areas or with flat/dark scenes first. Dropping the ISO speed below 400 (the nominal Canon Log ISO speed setting) may decrease the noise, though the dynamic range captured will also be narrowed slightly.
