= Excellent focusing
0= Acceptable focusing
Slight vignetting or moire phenomenon affects screen image, but film image shows no
traces of this.
L. = Acceptable focusing
The in-focus image in the central circular area may prove to be slightly out of focus on
the film. Focus on the surrounding matte area.
( ) = Indicates degree of exposure compensation needed (Center-Weighted metering only).
For F6 cameras, compensate by selecting "Other screen" in Custom Setting "b6:
Screen camp." and setting the EV level to -2.0 to +2.0 in 0.5 EV steps. When using
screens other than type B or E, "Other screen" must be selected even when the
required compensation value is "0" (no compensatio required). For F5 cameras,
compensate using Custom Setting #18 on the camera body. For F4-Series cameras,
compensate using the Exposure Compensation Dial for the focusing screen.
See instruction manual of the camera body for more details.
Blank box means not applicable.
Since type M screen can be used for both macrophotography at 1: 1 magnification ratio
and for photomicrography, it has different applications than other screens.
When using the B2/B3, E2IE3 and K2/K3 focusing screens in cameras other than those
listed above, refer to the columns for the B, E and K screens.
Lens Care
o Clean lens surface with a blower brush. To remove dirt and smudges, use a soft, clean
cotton cloth or lens tissue moistened with ethanol (alcohlo) 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.
o Never use thinner or benzine to clean the lens.
o To proect the lens surface from dirt or damage, the use of an NC filter is recommended
at all times. The lens hood also helps to protect the lens.
o Keep the lens cap in place whenever the lens is not in use.
o If you will not use the lens for a long time, protect it from rust and mold by storing it in a
cool, dry place. Also, do not store in direct sunlight, and keep it away from naphthalene
or camphor.
o Be careful not to get the lens wet or drop it in water. Water on the lens may cause
malfunction.
