Rumors have been circulating about the successor to the Canon 5D Mark III that will have 4K video recording (likely with a unsatisfying video codec if Canon remains consistent in its approach).
The main rumor has been 28mp, 9fps, and 4K video, to be released around September. One other source has suggested 32mp and a release date that makes it questionable if it will be out before the year end.
In a recent interview one of the Canon high up staff acknowledged that Canon as a company needs to move faster in releasing its products. Let’s hope the Mark IV will surprise us as the Mark III was a disappointing update from the Mark II.
