•
Sensor cleaning should only be attempted by
experienced imaging professionals.
•
Use a small, but powerful flashlight to look at the
sensor and filter, it’s easier to spot debris.
•
The OLPF assembly is removable and located
in front of the sensor. Once the lens mount is
uninstalled the OLPF can be easily removed
(2 screws) for cleaning.
•
Sensor cleaning must be done in a clean and
controlled environment.
•
Always have a forced-air bulb style blower and a
clean sensor cloth handy for more serious dirt.
•
Sensor cleaning solution (like Eclipse) should only
be used if absolutely necessary, and applied with
a soft wipe intended for sensor cleaning.
•
Cotton swabs aren’t a good idea, unless they are
wrapped in a sensor wipe material. They leave
behind more than they remove.
•
Never use your finger to get a speck of dust off,
it’s going to make things much worse.
•
Never blow on the sensor or OLPF.
•
Never put sharp objects near the surface of the
OLPF or sensor.
•
Always keep the Phantom body cap on the camera
when there is no lens attached.
Due to differences in various lenses and other mechanical
tolerances it may be necessary to adjust the lens mount
on the camera to obtain proper focus. In most cases,
changing a lens or replacing a mount will not require
adjusting the back focus, though it should be verified.
When the focus distance marks on a lens do not match
the measured distance between the sensor & subject,
it indicates the need to adjust the back focus.
By adjusting the back focus, you are changing the
distance of between the flange and the sensor plane.
Shims are included to assist in both slight and coarse
back focus adjustments.
