TIPS ON CAMERA CARE
Good camera care is primarily common-sense care. Treat your Nikon
EL2 camera as you would any other precision optical instrument and
it will provide you years of trouble-free service. Although ruggedly
constructed, your camera may be damaged by shock, heat, water or
misuse. By observing the following tips, you will be assured of the
longest possible service life.
• Fingerprints or dust on lens/prism surfaces will make viewing uncom­
fortable, and will generally contribute to a deterioration of optical
performance. Clean lens surfaces often using a quality lens tissue or
a soft lens brush; stubborn smudges should be wiped with lens tissue
moistened with methyl alcohol or a quality lens cleaner. Never clean
lens surfaces using cloth, paper towels, ordinary tissue, or any other
material that might scratch the lens surface; also, use cleaning fluids
sparingly to prevent seepage, and resulting damage to mechanical
components.
• When interchanging lenses, finders, etc., your camera is susceptible
to the entry of dust or other contaminants. It is a good idea to clean
moving body parts frequently to prevent the build-up of dust; here,
a lens brush and blower will come in very handy. When blowing out
the interior of the camera, however, avoid contact with the shutter
curtains, as they are easily damaged. Also, wipe the outer body sur­
faces using a silicone-impregnated cleaning cloth to remove finger­
prints, etc. quickly and easily. (Note that a silicone-impregnated
cleaning cloth should never be used to clean the lens surfaces.)
• When exposed to sudden temperature changes or high humidity, con­
densation may form on the lens surfaces. After using in these situa­
tions, always dry the camera thoroughly (and slowly) at room tem­
