Nikon F/41F instruction manual Setting the Reproduction Ratio

- OPERATION - continued------------------------

SETTING THE REPRODUCTION RATIO

To set the reproduction ratio between 1/11 X and 1 X, simply turn the focusing ring until the desired reproduc- tion ratio on the white scale clicks into place. If you want to shoot at magnifications between O.8X and 2X, attach the 2X close-up attachment lens (as described below), and set the focusing ring to the appropriate reproduction ratio on the orange scale.

Once the reproduction ratio is set, both the focused distance and aperture are automaticall y set.

Use the table on the next page to determine the repro- duction ratio according to the focused distance and the desired subject area .

• Mounting the 2X Close-Up Attachment Lens

Before mounting the 2X close-up attachment lens, make sure the aperture of the prime lens is set to f132. Then, grasp the attachment lens by its knurled ring, insert the threaded portion into the hole in the center of the ringlight, and while app lying slight pressure, screw the lens clockwise until it stops. Proper exposure value is then obtained according to the continuously variable reproduction ratio between O.8X and 2X.

The attachment lens can be removed with the aperture set to any value.

Note: With the attachment lens attached, the operative aperture is fixed at f/32 regardless of the aperture set on the scale.
