FOCUSINGThe fully automatic diaphragm o f the Micro-Nikkor enables focusing with maximum imagebrightness throughout the entire focusing rangeo f the lens. As the image is constantly viewedat the maximum aperture setting (i.e., f/4),the depth of field is minimized so that theimage snaps in and out of focus rapidly anddistinctly.To focus, turn the focusing ring until the imageon the focusing screen appears sharp and crisp.Via the special focusing helicoid, the Micro-Nikkor operates continuously f r o m infinity(°°) to 0.47m (1.55 ft) for a reproductionratio of 1:2.The distance scale on the focusing ring ismarked in both meters (white) and feet (yel-low). These figures indicate the distance fromthe subject to the camera's film plane.Note: The exact position of the film plane is indicat-ed on all cameras for convenience when measuring.On Nikon F/F2 cameras, the top edge of the serialnumber is the exact position of the plane. Onother Nikon and Nikkormat cameras, the plane isindicated by the symbol (-Q-)
