Maximum is infinity for the two at leftLess than 4 feet for the one above

Sensor is 1x2/3

Stamp is 1 highNOTE 1:1 means Life-sized Life-sized means 1 long subject will fit exactly on a 1 long sensor, for example At its maximum magnification (Substitute 5 for a 4x5 view camera, for example)Effect of Various Macro AccessoriesOn Image MagnificationAll images are maximum possible magnification for devices used

Note these 2 have almost the same magnification Macro lens is not essential

Fixed Aperture; Changing Focus PointImage Size (& Composition) Changes

Focus point distance increases from left to right aboveCamera position & all other settings remain constantNOTE - Subject size shrinks as focus distance increasesWont work for focus stacking (combining multiple exposures to increase DOF)But thats another subject entirely (& a focusing rail job)Except for focal pointSame as previousslide at f/11
