Field of View: Sort of an undocumented
feature (not mentioned in the SJCAM marketing literature that we
found) is the ability to change the camera's field of view from
wide (170 degrees) to "medium" and "narrow".
ISO Equivalents: Not usually available in
action cameras, the ISO can be set to auto (default) or 100, 200 or
White Balance: Another uncommon feature
is the ability to modify white balance from auto to cloudy,
daylight and for incandescent lighting.
Exposure Values: The SJ4000 allows
exposure changes from +3.0 to -3.0 EV in 0.33 step increments, a
very uncommon feature in this type of camera.
Sharpness: Sharpness of recording can be
set to "soft", "normal" or "strong".
Dash Cam/Loop Recording: Yes, the SJ4000
can even be used for loop recording as a dash cam, although
mounting and powering the camera is challenging, so this feature
isn't as valuable as it could be.
Underwater Setting: Not sure what this
does (probably accounts for light color changes under water) but
it's there as an on or off setting.
Motion Detection: The SJ4000 can be set
(on/off) to start recording whenever motion is detected in front of
the lens. Handy for all you stealthy Philip Marlowe types.
Frequency: Check to make sure the
frequency is set correctly for your country (50 Hz or 60 Hz) before
you connect the SJ4000 to a TV set. Ours was set at 50 Hz even
though we use 60 Hz in the U.S.
