LENS HOOD
A slip-on type lens hood comes with the lens. Since the lens hood is effective for eliminating harm-
ful rays, we recommend using it when photographing. When storing, the lens hood should be put
over the lens in reverse.
The lens hood is provided with two opposing lock screws.When using the hood, loosen the screw,
attach the lens body to the hood, and then tighten the lock screws.
INFRARED INDEX
When black & white infrared film is used, a red filter should also be used. The nature of red filters
requires focus correction.The red scale R mark in the range scale is the infrared index. Focus in a
normal way, and then read the range scale and shift to the infrared index.Then install the red filter
and photograph.To make any focusing corrections, switch the focus mode to manual and turn the
focusing ring.
CAUTION
To the customers who use a camera with an incorporated strobe:
For flash photographs, please use an externally installed strobe. If the built-in strobe is used for
flash photography, the lens will interrupt the light path of the strobe and semicircular shading will
appear at the bottom of the picture. Also, see the "Built-in Strobe" section in the instruction manu-
al of your camera.
TO ENSURE LONG-TERM SATISFACTION
1. Avoid touching the lens surface. Use a photographic brush or blower to remove dust from the
lens surface.When not using the lens, put a cap on for protection.
2. Use a lens cleaning tissue or lint cloth with a drop of cleaning solution to clean fingerprints or
dirt on the lens surface with a rotary motion from the center to edge. Use a silicon cloth to clean
your lens barrel.
3. Fungus is an enemy of your lens. Clean the lens after shooting at seaside or in a humid place.
Store your lens in a clean, cool and dry place. If you find fungus on your lens, please consult a
repair shop or nearby photographic store.
4. Do not touch the lens' camera-interface contact since dust, dirt, and/or stains may cause a con-
tact failure between the lens and camera.
5. When using your equipment [camera(s) and/or lens(es)] in an environment where the tempera-
ture changes from one extreme to another, make sure to put your equipment temporarily in a case
or a plastic bag for some duration in order for them to go through a gradual temperature shift.This
will reduce potential trouble of your equipment.
