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 pling ridge provided. The ridge and the auto diaphragm function to gether to permit full aperture exposure measurement; the lens is also fitted with a meter coupling shoe to permit the same operation with Nikon cameras which lack the Al facility. In terms of optical perform ance, the Micro-Nikkor's excellent flatness of field is a stand-out feature, enabling virtually distortion-free images at all reproduction ratios. The application of Nikon Integrated Coating (NIC) further en hances performance by increasing image contrast, while reducing flare and ghost, for outstanding color reproduction. When the Micro-Nikkor 1 05mm is used with the special Auto Extension Ring PN-11 or PN-1, focusing is further extended from 1 : 2 to 1 : 1 for full life-size reproduction. To get the best results from your Micro-Nikkor 105mm f/4, read this instruction manual carefully. Keep the manual handy for reference until you have thoroughly familiarized yourself with the lens and its operation. A few minutes of preparation will help you avoid costly mistakes. 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), conventional "manual" maximum aperture indexing is required. In both cases, refer to the camera's instruction manual. 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), brightness throughout the entire focusing range the depth of field is minimized so that the 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 operates continuously from infinity (°°) to 0.47m (1.55 ft) for a reproduction ratio of 1:2. The distance scale on the focusing ring is marked in both meters (white) and feet (yel low). These figures indicate the distance from the 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 serial number is the exact position of the plane. On other Nikon and Nikkormat cameras, the plane is indicated by the symbol (-Q-) Reproduction Ratio The reproduction ratio is the numerical expres Recommended Focusing Screens sion of the relationship between the image size Nineteen different interchangeable focusing (to be recorded on the film) and the actual size screens are available for F and F2 Nikon of the subject.

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 without calculating the distances required. To photograph at a repro duction ratio of 1 : 5, for example, just turn the focusing ring until the number "5" is aligned with the distance scale index; then aim at the subject and adjust your position (close to, or farther away from, the subject) until the image appears sharp and crisp on the focusing screen. 8 NOTES ON FOCUSING Depth of Field Camera Shake: Close-up photography poses Depth of field refers to the zone of acceptable several problems not encountered in general focus extending in front of and behind the photography. One of these is sensitivity to plane of sharpest focus. As this zone is excep vibration—the magnification of the image is so tionally shallow at high reproduction ratios, high that even slight displacement during previewing is desirable before shooting. To shooting results in a blurred image.

When close-up attachments such as a PN ring or bellows are used, the exposure measure ment method is shown in the table on the left. When the lens is mounted in the reverse posi tion, the stop-down method should be used. See the instruction manual supplied with your camera or Photomic viewfinder for details. Caution: When the stop-down method is used at small apertures, a finder eyecup should be attached to the eyepiece to ensure complete exclusion of stray light. 10 Without TTL Metering At close ranges (reproduction ratios greater than 1:10), the amount of light reaching the film decreases as the lens-to-film distance in Exposure Reproduction Exposure increase creases.
