Technical Notes—Caring for the Camera
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.
Servicing the Camera and Accessories
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.
