FOV at the same magnification scale should be equal with 35mm and *istD when using the sme lens. *istD will have greater DOF than 35mm at equal distance to subject. But then you will see just a part of image seen on 35mm frame, thus you will have to make the distance between you and the subject greater to maintain equal magnification scale. Am I right?
