6. Focusing at a predetermined reproduction ratio The reproduction ratio is the relation between the size of the image recorded on film and the actual subject size. If, for example, the image on the focusing screen is one-fifth the actual subject size, the reproduction ratio is 1:5. En To photograph at a predetermined reproduction ratio, use the following procedure: a Manually turn the focus ring until the desired reproduction ratio scale number is aligned with the distance index line. b Aim at the subject, then change your position, moving closer to or farther away from the subject, until the image in the viewfinder sharpens. To obtain the appropriate reproduction ratio for each focused distance, see the table on page 150. 7. Notes on close-up photography and duplication work Camera shake The AF-S Micro NIKKOR 60mm f/2.8G ED provides such exceptionally high image magnification that even the slightest movement during shooting can cause the image to blur. Be sure to mount the camera on a tripod and use a cable release or remote cord to release the shutter. Close working distance At the high reproduction ratios used in close-up shooting, the depth of field is very shallow. To ensure greater depth of field, stop down the lens, then carefully position the camera to ensure the most important surface of the subject is in the same zone of sharp focus. • Use manual focus when using the close-up lens.
