forgot to mention: I did not use zones, but my default AF mode is full frame subject detection AF.

AF benefits from input from the photographer - with any brand of camera.

Full frame AF is about as inappropriate an AF starting point as can be selected when wanting AF to detect a subject occupying a very small percentage of the image area, similar to your examples.

In lots of ways good photography is similar to learning to play a piano - it takes practice to develop skill in either activity.
