magnification ratio and for photomicrography, it has different applications than other screens.
• For F5 cameras, only EC-B, B, E, J, A, L focusing screens are usable in Matrix Metering.
• 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.
12. 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.
• 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.
• Do not get water on the lens or drop it in water as this will cause it to rust and malfunction.
• Reinforced plastic is used for certain parts of the lens. To avoid damage, never leave the lens in
an excessively hot place.
