Re: Picture sharpness on Canon M6 ii with Tamron 100-400mm

I am not quite sure how to judge whether or not the lens is adequately sharp. On the face of it, the below (taken in similar bright conditions, but clearly much closer to me) looks fine, but when zooming into the picture, the feathers are somewhat blurry.

Is this essentially the level of sharpness I can expect from this lens?

Also, I went out again today to capture action shots of the kingfisher, but got incredibly frustrated with the AF tracking: I press the screen exactly where the bird is, asking the camera to track it, but it either focuses elsewhere (e.g. the background) or it expands that focusing box onto the entire perch instead of just the bird, which is otherwise clearly outlined against the background (bright blue on grey is pretty stark!). Getting the camera to then follow the bird in flight for even a short burst is then of course impossible.

Am I expecting too much of the camera or do you find the tracking works fine?
