Barn Swallows at the lake (second attempt)

I switched from 1/2000 of a second shutter speed to 1/5000 and I also switch from the RF 100-500mm f/4.5-7.1 to the RF 70-200mm f/2.8 L IS USM Z lens. The photos are better but still not as chrisp and clear as I am hoping to eventually get. I posted a question on a forum asking for advice and got some. Also included are some other feathered friends.
