Abstract: This invention provides an improved method and hardware/firmware to obtain photographs of any subject ranging from insects to landscapes. It allows either manual or fully automatic collection of images in small focal distance steps by externally rotating the focus ring for any camera and any lens. The acquired photos may then be processed using commercial software to obtain a final highly detailed, entirely in-focus image. The manual method employs a very fine adjustment screw interfaced with a tab extending out from the focus ring. The automated method employs a controller and stepper motor. It drives a lead screw configured to interface with a tab extending out from the focus ring or rotates solid gears, or a motor-pully gear interfaced with a gear band secured to the focus ring. The combination of electronic and mechanical advantages leads to the possibility of focus ring adjustments smaller than 0.001 degrees.
