I know that the closer the distance to your subject is, the smaller the DOF is. This is true for macro lense, diopters, extension tubes, reverse lenses etc.
But suppose I have a magnification of 1:1, either with a macro lens, diopters, extension tubes or a reverse lens: how is DOF between these methods? Do they all have same DOF using the same aperture?
Please let me know your thoughts.
