User manual NIKON AI MICRO-NIKKOR 105MM F/4

[. . . ] The ridge and the auto diaphragm function together 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 performance, the Micro-Nikkor's excellent flatness o f field is a stand-out feature, enabling virtually distortion-free images at all reproduction ratios. The application o f Nikon Integrated Coating (NIC) further enhances performance by increasing image contrast, while reducing flare and ghost, for outstanding color reproduction. [. . . ] The image on the f i l m , however, shows no trace of this. • = Not usable = With these lens-screen combinations the viewfinder can be used only for focusing; exposure measurement is not possible. 7 °] •m o s o « Wmr ® * » • 0 Reproduction Ratio The reproduction ratio is the numerical expression of the relationship between the image size (to be recorded on the film) and the actual size of the subject. For example, if the image on the focusing screen is one-fifth the actual size of the subject, the reproduction ratio is said to be 1:5, and is indicated on the reproduction ratio scale of the Micro-Nikkor 105mm f/4 by the number "5'! 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. Using either o f these scales, you can photograph at a predetermined ratio without calculating the distances required. To photograph at a reproduction ratio o f 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 f r o m , the subject) until the image appears sharp and crisp on the focusing screen. 8 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. Depth of field can also be observed by reading the color-coded indicators inscribed on the lens barrel. The pairs of colored lines on either side of the white distance scale index line correspond to f/numbers of the same color on the aperture scale. At close distances, so little is in focus that the depth-of-field tables on pages 13 ~ 14 are more useful. Camera Shake: Close-up photography poses several problems not encountered in general photography.
