MOUNTING THE LENS A

Align the green aperture index © on the lens with the mounting index on the camera and insert the lens in the camera's bayonet mount. Then twist the lens counterclockwise until it clicks into place. (To remove, depress the lens release button on the camera and twist the lens clockwise.)

Notes:

1)When mounting the lens on an Al-type camera with a meter coupling lever, make sure the lever is in the "down" position; when mounting on a camera without this lever (non-AI type), "manual" maximum aperture indexing is required- For more information, refer to the camera's instruction manual.

2)When the lens is used with the Nikon F-401/N4004, the camera meter coupling function does not operate and the exposure indicator LEDs do not appear.

FOCUSINGB

To focus, rotate the focusing ring ® until the image in the viewfinder appears sharp and crisp.

For pinpoint focusing, focus with the lens in the 70mm position, then move back to the best focal length for the desired picture composition.

ZOOMINGC

This allows you to 'trim' your picture to fit the frame exactly. To zoom in and out, look through the viewfinder and turn the zooming ring (?) to the right and left until the desired composition is framed on the focusing screen. For reference, a three- position scale to indicate focal length settings (35mm, 50mm and 70mm) is engraved on the zooming ring, but you can also use intermediate settings.

MACRO FOCUSING

Although normal focusing is possible from infinity to 0.5m (2 ft), you can focus even closer at any focal length setting with a smooth action of the focusing ring. The orange "M" and line (?) indicate macro mode focusing. The minimum focal distance and maximum reproduction ratio are 0.35m (1 ft) and 1:4.4 respec- tively.

At a focal length of 70mm, its reproduction ratio is 1:4.4, while at 35mm, it becomes 1:8.3.

It is recommended to use longer focal lengths as much as possible for macro focusing, because vignetting may occur at shorter focal length settings.

Note: Although this lens has macro focusing capability, a Micro-Nikkor lens is recommended for document copying or slide duplication where critical sharp- ness is required.
