7. Recommended focusing screens
Various interchangeable focusing screens are available for certain Nikon SLR
cameras to suit any picture-taking situation. The ones recommended for use with
this lens are:
: Excellent focusing
: Acceptable focusing
Slight vignetting or moiré patterns appear in the viewfinder, but not on the film.
—: Not available.
Blank box means not applicable. 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.
• When using the B and E focusing screens in cameras other than those listed
above, refer to the columns for the B and E screens.
8. 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.
