Thanks to everybody for all the ideas and hints; the first thing I tried is switching into servo af and/or shooting several pictures in rapid succession, and that already helps a lot.


Regarding the "DoF parrallel to the movement", is the focal plane typically a really flat plane? (I suppose it can't be spherical, at least not with the camera (sensor) as center point, because otherwise focus-and-recompose would work better&hellip
