You didn't disclose how many total shots you took, but 500 keepers is insanely impressive considering the subject matter! From what I'm experiencing, this camera doesn't miss too often, it's just so confidence-inspiring. Along with the higher FPS, the more consistent + accurate AF is the biggest advantage I'm seeing over my 5D4. I'm not binning as many shots due to soft/missed focus.
It was extremely dark out there today so I had to keep shutter speeds down. I was playing around BT 1/500-800. In the morning when first light appeared and until about 11:00Am.... I would go to 6400-12800 iso at F/2.8-3.2 with a shutter at 1/640 or above..... so I was playing a lot at 1/400 and had a lot of motion in the shots. It was insanely dark most of the day. When the light came out I was able to get a shutter at 1/640-1200-2000 and i had very few misses. I took about 900 shots on this 8 hr trip...lost of burst shots
