Operation 4k Camera
Testing the quality of 4k in a couple of cameras.
I brought 2 cameras to the 2022 Boston Marathon near the 5-mile mark - my GoPro Hero 9 and the Canon xa40.
Here is a sample of 4K footage from both cameras. They were taken from the same point moments apart. It's a good idea of the quality of the videos produced by these cameras.
GoPro Hero 9 - Default Activity Settings in 4K mode with wide lens.
Canon xa40 - Auto Focus and Auto Exposure in 4K mode
