861 Caring for the Camera
D Foreign Matter on the Image Sensor
Foreign matter entering the camera when lenses or body caps are removed
or exchanged (or in rare circumstances lubricant or fine particles from the
camera itself) may adhere to the image sensor, where it may appear in
photographs taken under certain conditions. To prevent entry of foreign
matter when attaching the body cap or exchanging lenses, avoid dusty
environments and be sure to remove all dust and other foreign matter that
may be adhering to the camera mount, lens mount, or body cap. To protect
the camera when no lens is in place, be sure to replace the supplied body
cap. Should you encounter foreign matter that cannot be removed using the
image sensor cleaning option (
0 858), clean the image sensor as described
in “Manual Cleaning” ( 0 860), or have the sensor cleaned by authorized
Nikon service personnel. Photographs affected by the presence of foreign
matter on the sensor can be retouched using the clean image options
available in some imaging applications.
D Servicing the Camera and Accessories
The camera is a precision device and requires regular servicing; Nikon
recommends that the camera be inspected once every one to two years, and
that it be serviced once every three to five 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
flash units, should be included when the camera is inspected or serviced.
