FOREWORD The Micro-Nikkor 105mm f/4 is a special telephoto lens designed for close-up photography at high reproduction ratios. It features the same optical construction as the much-acclaimed Bellows-Nikkor 105mm f/4, but with a special focusing helicoid that enables operation from infinity (°°) to a reproduction ratio of 1 : 2 (half life-size) without the need for any adapters. The lens offers "automatic maximum aperture indexing" (Al) with suitably equipped cameras, via the meter cou pl

MOUNTING THE LENS Position the lens in the camera's bayonet mount, aligning the mounting indexes on the camera and the lens. Twist the lens counter clockwise until it clicks into place. To remove, depress the lens release button on the camera and twist the lens clockwise. Note: When mounting the lens on a camera with a meter coupling lever (Al type), make sure that the camera's meter coupling lever is correctly positioned; when mounting on a camera without this lever (non- Al type), co

FOCUSING The fully automatic diaphragm of the Micro- of the lens. As the image is constantly viewed Nikkor enables focusing with maximum image at the maximum aperture setting (i.e., f/4), the depth of field is minimized so that the brightness throughout the entire focusing range image snaps in and out of focus rapidly and distinctly. To focus, turn the focusing ring until the image on the focusing screen appears sharp and crisp. Via the special focusing helicoid, the Micro- Nikkor opera

FOCUSIN G - continued Focusing at Predetermined Ratio Above the distance scale on the focusing ring are two reproduction ratio scales inscribed in orange. The inner scale, with figures from 1:10 to 1:2, represents the reproduction ratios ob tained when the lens is used alone. The outer scale figures (i.e., 1:2 to 1:1) represent the ratios possible when the lens and, PN-1 or PN-11 ring, are used together. Using either of these scales, you can photograph at a pre determined ratio withou

NOTES ON FOCUSING Camera Shake: Close-up photography poses Depth of Field several problems not encountered in general Depth of field refers to the zone of acceptable photography. One of these is sensitivity to focus extending in front of and behind the vibration—the magnification of the image is so plane of sharpest focus. As this zone is excep high that even slight displacement during tionally shallow at high reproduction ratios, shooting results in a blurred image. Therefore, previ
