Since the 5D Mark IV has a 1.7 crop in 4K mode I put on the Tokina 11-16mm 2.8 Lens ( effective view 18-27mm ) with Tiffen ND Filter ) and kept the shutter at 1/50 while shooting 4K24 MJPG. Ronin-M gimbal was also used. Time: 0:00-0:26 was shot at 11mm ( 18mm effective crop ) Time: 0:27-1:10 was shot at 16mm ( 27mm effective crop ) Time: 1:05 I quickly lifted the Ronin-M gimbal up and touched the screen to focus on the cat hence the quick jerk motion. Flat Color Profile then a simple LUT was added to the footage. 4K film grain added and some sharpening in post since the Canon Picture profile reduced sharpening. I had the Tokina 11-16 Lens a long time and used to use it on the Canon 60D when I shot cropped sensors. Glad I didn't get rid of the lens because now it can replace my Canon 16-35mm 2.8 for the Gimbal wide shots when shooting 4K on the Canon 5D Mark IV. The auto focus worked fairly well with the third party Tokina lens but as you can see it sometimes lost focus track. I assume the Canon dual pixel auto focus mostly looks for peoples faces and not little kitty wind chimes. But all in all it stayed on focus fairly well.
