Adjusting the Lens
The lens on the front of the camera can have its focus adjusted.
We set the focus for typical use before shipping the cameras out, so you
shouldn’t need to adjust anything. The focus is set from approximately
1m to infinity for non-underwater use.
If you want to record events very close to the lens (<1m away) or use
the camera underwater, then you’ll need to adjust the focus.
Focusing the Camera for use Underwater
The lens needs to be adjusted to compensate for the different way
light moves through water as opposed to air.
You’ll need to rotate the lends 95 degrees counter-clockwise, as shown
in the diagram.
If you look closely
near the lens, there
are two markings. The
red marking at the 0
degree point indicates
normal focus, whereas
the white mark at 95
degrees marks the
optimal focus for
underwater.
The outer adjustment ring on the lens has a small white mark, which,
by default, should align with the red mark at the 0 degree mark.
Note that these markings are for quick-reference only, and for the best
results, connect the
Atom HD
to a television and adjust the focus by
sight - there’s no substitute.
