Canon DIGISUPER 27AF 手册

1.  Dust or fingerprints on the lens surface 

Gently blow or brush away dust or dirt on the lens surface 

using a lens blower or a soft lens brush. 

Remove any fingerprints or other stains with a soft clean 

cotton cloth moistened with lens cleaning fluid or lens 

cleaning paper (Shilbon paper, etc.). 

Gently swirl the cloth or paper over the lens surface. Start 

first at the center area of the lens and rub with a circular 

motion, then gradually shift the circle until whole lens 

surface has been covered. 

Be careful not to rub dust across the lens, as the lens 

surface may be scratched.

2.  Periodic inspection 

A periodic inspection (about once a year) is 

recommended. 

The inspection and maintenance interval depends on 

the operating conditions, the frequency of use, and the 

environment. If required, overhaul the lens.

1.  Always attach the hood cap and the dust cap before 

storing the lens. 

Storing the lens without these caps attached may present 

a fire hazard due to light convergence effect.

1.  If moisture enters the lens due to mist or light rain, etc., 

immediately wipe away any water with a dry cloth and 

then seal the lens in a vinyl bag together with a desiccant 

(as fresh as possible) to completely remove the moisture 

from inside the lens.
