Nikon D50 用户手册

Cleaning the Low-Pass Filter
The low-pass fi lter is extremely delicate and easily damaged.  Nikon recom-
mends that fi lter be cleaned only by Nikon-authorized service personnel.  
Should you choose to clean the fi lter yourself, follow the steps below.

1

 Raise the mirror as described in steps 1–3 on the preceding page.

2

 Re move dust and lint from the fi lter with a 

blow er.  Do not use a blower-brush, as the 
bris tles could damage the fi lter.  Dirt that can 
not be removed with a blower can only be 
re moved by Nikon-au 

tho rized ser 

vice per-

 son nel.  Un der no circumstances should you 
touch or wipe the fi l ter. 

3

 Turn  the cam era off.  The mirror will return 

to the down position and the shutter cur tain 
will close.  Replace the lens or body cap.

The D50 is a precision device and requires regular servicing.  Nikon recommends that 
the camera be inspected by the original retailer or Nikon service representative once 
every one to two years, and that it be serviced once every three to fi ve years (note 
that fees apply to these services).  Frequent inspection and servicing are particularly 
recommended if the camera is used professionally.  Any accessories regularly used 
with the camera, such as lenses or optional Speedlights, should be included when the 
camera is inspected or serviced.
