Nikon 60mm-f-28G-AF-S-Micro-Nikkor: Focusing at a predetermined reproduction ratio Notes on close-up photography and duplication work

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

En

size, the reproduction ratio is 1:5.

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.

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.
