Using a tripod (Fig. E)
This lens is equipped with a detachable rotating tripod collar. When using a tripod,
attach it to the lens’ tripod collar instead of the camera. To attach the tripod collar to
the lens, follow these steps:
1 Loosen the tripod collar lock screw 1 slightly.
2 Insert the lens by aligning the tripod collar alignment index on the lens with the
mark on the tripod collar 2.
3 Turn the lens to an appropriate position index 3 (three indexes are provided
every 90°) on the tripod collar by aligning the tripod collar alignment index on
the lens, then tighten the screw. (If the screw is not tight, the lens may
accidentally come off the tripod collar.)
Removing the tripod collar
First loosen the tripod collar lock screw until the tripod collar rotates freely. Do not loosen
the lock screw too much as it may come off. Then align the tripod collar alignment index
on the lens with the mark on the tripod collar and pull off the tripod collar.
Attaching bayonet hood HB-24
Line up the white index on the hood with the hood mounting index on the front of the
lens and turn the hood clockwise (as viewed from the front of the lens) until it click
stops. To facilitate attachment or removal of the hood, hold it by its base rather than
its outer edge. To store the lens hood, you can attach it in the reverse position.
Reproduction ratio and shooting distance
Normal focusing extends from infinity to 2.3m (7.5 ft.). A maximum reproduction
ratio of approx. 1:25 is obtained at the 80mm setting, while a reproduction ratio of
1:4.8 is possible at 400mm.
Lens care
•Clean the lens surfaces with a blower brush. To remove dirt and smudges, use a
soft, clean cotton cloth or lens tissue moistened with ethanol (alcohol) or lens
cleaner. Wipe in a circular motion from center to outer edge, taking care not to
leave traces or touch other parts of the lens.
•Never use thinner or benzene to clean the lens as this might damage it, result in a
fire, or cause health problems.
•To protect the front lens element, an NC filter is recommended at all times. A lens
hood also helps protect the front of the lens.
•When storing the lens in its lens case, attach both front and rear caps.
•When the lens will not be used for a long time, store it in a cool, dry place to
prevent mold. Also store the lens away from direct sunlight or chemicals such as
camphor or naphthalene.
