This image was created on 26 MAY 2020 at Fort DeSoto. I used the Induro GIT 304L/FlexShooter Pro-mounted Sony FE 600mm f/4 GM OSS lens, Sony FE 1.4x teleconverter, and the blazingly fast AF King, the Sony Alpha a9 II Mirrorless Digital Camera Body. ISO 640. Exposure determined by Zebras with ISO on the rear dial: 1/2500 sec. at f/5.6 in Manual mode. AWB at 7:26pm with the sun going in and out. Center Zone AF-C was active at the moment of exposure and performed beyond perfection (even as seen here with backgrounds other than sky).
I tried a new AF technique that performed amazingly well. To learn lots more about the creation of this image see the Not in the Least: the Fort DeSoto Least Tern Colony. Plus an Astounding 600mm f/4 AF Tip ... blog post here.
