[QUOTE="WayneF, post: 424619, member: 12496"] You're kidding yourself. Your Wikipedia link about macro just converts focal length to magnification (as they clearly show). There is no magnification without focal length. 1:1 is a magnification, and it is like Wikipedia says: "more convenient" for macro. It is not different rules, its about how lenses work. There are just more approximations at macro. Like they say there: [ATTACH=CONFIG]143823._xfImport[/ATTACH] m is magnification. f is focal length. s there is subject distance to sensor plane. s-f is distance in front of Thin Lens. But at macro, we don't know f or s-f. But if 1:1, then f and s-f are equal (1:1), therefore f = s/2 (Thin Lens). What exactly do you consider to be or to show DOF in your lightbulb pictures? [/QUOTE]
