[. . . ] € Do not attach the following accessories to the lens, as they might damage the lens’ CPU contacts: Auto Extension Ring PK-1, Auto Extension Ring PK-11*, K1 Ring, Auto Ring BR-4**. € Other accessories may not be suitable for use with certain cameras. [. . . ] Those which are recommended for use with your lens are listed on the reverse side of this sheet. It is possible, however, to determine depth of field by using the scale provided on reverse side of this sheet. Place scale B over scale A so the top edge of scale B is aligned with the focal length in use and the distance is aligned with the central indicator line on scale A. For example, if the lens is prefocused at 2m with the focal length at 50mm and the aperture at f/22, the depth of field will be from approx. Puis, placez l’échelle B sur l’échelle A pour que le sommet de l’échelle B soit aligné sur la distance focale utilisée et que la distance soit alignée sur la ligne indicatrice centrale de l’échelle A. A) For programmed auto or shutter-priority auto shooting, use the minimum aperture lock lever to lock the lens aperture at f/22. Slide lock lever in the direction of the aperture ring and so the white dot on the lever aligns with the orange dot. 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 and not to touch the other lens parts. € To protect the lens surface from dirt or damage, the use of an NC filter is recommended at all times. € Attach both the front and rear caps when the lens is stored separately. € To ensure proper fit of the lens when stored in the leather lens case, set the lens focus ring to the infinity (∞) and the zoom ring to the 70mm setting. [. . . ] For F4-series cameras, compensate using the Exposure Compensation Dial. Since type M screen can be used for both macrophotography at a 1:1 magnification ratio and for photomicrography, it has different applications than other screens. [. . . ]
