A7r4 and the 200-600 OSS.

To say the least, I am thrilled with this kit's ability to focus! Awesome.

3 Mallards incoming.

Against a dark background the sensors picked up and tracked the flights 100%. Also, just enough depth of field to cover the focus range needed. Just enough ISO, and shutter speed to keep it fairly sharp, with only a little noise.

All good fun, and practice to the next time!

Thanks for looking.
