      And background focus is based on the ratio of distances between the camera and the foreground object and the background and the foreground object. The fstop values are meaningless without knowing that information.

        For the same foreground/background the fstop is the ONLY factor in changing the depth of field.

      I’d argue for a newbie this is very useful to explain the difference between the settings. It took me forever to figure these out with trial and error back in the 90’s

      If you have a better guide, please share.
