Nikon 85mm-f-35G-ED-AF-S-VR-DX-Micro-Nikkor: ■ Setting the aperture ■ Depth of field ■ Focusing at a predetermined reproduction ratio ■ Notes on close-up photography and reproduction work

■ Setting the aperture

Use the camera to adjust the aperture setting. When exposure (or

Jp

shooting) mode is set at “A” or “M”, the camera will control aperture to

maintain the effective f-number (up to approx. 1.1 stops) even if shooting

En

distance is changed.

De

■ Depth of field

If your camera supports depth-of-field preview, the effects of the

aperture setting can be previewed in the viewfinder before shooting.

■ Focusing at a predetermined reproduction ratio

Es

(Reproduction ratio scale)

The reproduction ratio is the relation between the size of the image

Sv

recorded on the image sensor and the actual subject size. If, for example,

the image on the image sensor is one-fifth the actual subject size, the

reproduction ratio is 1:5.

Ru

To photograph at a predetermined reproduction ratio, use the following

procedure:

Nl

1 Manually turn the focus ring until the desired reproduction ratio scale

number is aligned with the distance index line c.

It

2 Aim at the subject, then change your position, moving closer to or

farther away from the subject, until the image in the viewfinder

Cz

sharpens.

■ Notes on close-up photography and reproduction

Sk

work

Camera shake

Ck

This lens provides such exceptionally high image magnification that

even the slightest movement during shooting can cause the image to

Ch

blur. Therefore, the use of a tripod and a cable release or remote cord is

highly recommended to prevent the effects of camera shake.

Kr

Close working distance

At the high reproduction ratios used in close-up shooting, the depth of

field is very shallow. To ensure sufficient depth of field, stop down the

lens, extend the exposure time, and carefully position the camera so that

the most important portion of the subject is parallel to the surface of the

image sensor to ensure sharp focus.
