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 f r o m infinity (°°) to a reproduction ratio of 1 : 2 (half life-size) w i t h o u t the need for any adapters.
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 counterclockwise until it clicks into place. To remove, depress the lens release button on the camera and twist the lens clockwise.
FOCUSING The fully automatic diaphragm o f the MicroNikkor enables focusing with maximum image brightness throughout the entire focusing range o f the lens. As the image is constantly viewed at the maximum aperture setting (i.e., f / 4 ) , 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.
Recommended Focusing Screens Nineteen different interchangeable focusing screens are available for F and F2 Nikon cameras to suit any type of lens or picturetaking situation. Those which are recommended for use with this Micro-Nikkor 105mmf/4 lens are listed below.
FOCUSING - 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 obtained 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.
NOTES ON FOCUSING Depth of Field Depth of field refers to the zone of acceptable focus extending in front of and behind the plane of sharpest focus. As this zone is exceptionally shallow at high reproduction ratios, previewing is desirable before shooting. To preview, press the depth-of-field button on the camera and the lens will close to the preselected aperture to allow you to see how much background and foreground is in focus.
DETERMINING EXPOSURE Exposure measurement Camera Close-up attachment Al PN-11 Full aperture Al PN-1 Stop-down Al Bellows, E2 and K rings and close-up lenses Stop-down non-AI PN-11 *non-AI PN-1 non-AI Bellows, E2 and K rings and close-up lenses Stop-down Full aperture Stop-down *With this combination, conventional "manual" maximum aperture indexing is required. With Built-in T T L Metering The Micro-Nikkor has a fully automatic diaphragm with settings from f/4 to f/32.
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 increases. When non-TTL measurement is used for this range, the result is underexposed photographs unless compensation has been made for this decrease.
