Review - Canon 5D Mark IV for serious video makers

MANHATTAN BEACH, Calif. The Canon 5D series of camera ushered in the DSLR video revolution and made it easier than anyone to be a working photographer.
That's how good the cameras were.

The new 5D Mark IV, aimed at serious photographers and videographers is even better.
It's not cheap--$3,500 for the body only, without a lens, but the two weak spots the new edition addresses are pretty major. So if you have a previous 5D, you will want to upgrade. Here's why:
--Autofocus for video. The previous two models as good as killed the pro video camera. The full-frame image sensor is 20 times the size of those found in consumer video cameras, and the video seen has a high-end, dreamy cinema quality. The only problem was the struggle to focus for video. You could use the autofocus to compose your shot--but once you started recording, if you moved the camera, or the subject did the same, you went out of focus.
Newer cameras from Canon, the 70d and 80D, fixed that, with a follow focus that worked flawlessly. Now those same tools come to the 5D Mark IV, and it’s most welcome. I tested the 5D Mark IV focus by bringing it to Venice Beach, and following folks walking down the street, where folks came in and out of our shot, as well as a skate park. The focus was flawless.
I did a test shot the other night at 9 p.m., in virtual darkness, and tried a video shot where I walked in and out of the camera. Amazingly, I was somehow sharp.
Beyond focus for video, the new 5D does a better job of quickly finding focus for stills as well.
