Ok, chalk it to the idiot user error.
I was taking pics from inside the house of things outside.
Finally got a half decent day, weather-wise, and went outside and things got a lot better with sharpness. It still seems to search a bit at times but much better. BTW, I was in the kitchen yesterday and noticed another hawk right outside of the window! This one is a bit smaller than the last one and I saw it a few days ago but missed the opportunity to shoot it. But not yesterday...
If I was standing on my window sill I could have jump over an landed on it.
