Sony RMT-840 - Manual (Page 30)

Recording 30
To restore automatic adjustment
Press SHUTTER SPEED, or set the AUTO
LOCK switch to AUTO LOCK.
b Note
• If you set the AUTO LOCK switch to AUTO
LOCK, other manually adjusted items (iris, gain,
white balance) also become temporarily automatic.
z Tip
• It is difficult to focus automatically at a lower shutter
speed. Manual focusing with your camcorder
attached to a tripod is recommended.
• The picture may flicker or change colors under
fluorescent lamps, sodium lamps, or mercury lamps.
Adjusting the volume of light
– ND FILTER
You can record the subject clearly by using
the ND filter when the recording
environment is too bright.
There are 2 levels of ND filter setting. ND
filter 1 reduces the volume of light to about
1/6, and ND filter 2 to about 1/32.
If [ND1] or [ND2] flashes in the standby
mode, set the ND FILTER switch to the
respective position.
If [ND1] flashes
Set the ND FILTER switch to 1 to turn on
[ND1].
If [ND2] flashes
Set the ND FILTER switch to 2 to turn on
[ND2].
If [ND OFF] flashes
Set the ND FILTER switch to OFF to turn off
the indicator.
b Note
• If you move the ND FILTER switch during
recording, the picture and sound may be distorted.
• If you adjust the iris manually, no ND filter indicator
will appear even if the ND filter should be activated.
z Tip
• If you close the iris extensively when recording a
bright subject, diffraction may occur, resulting in a
fuzzy focus. (This is a common phenomenon with
video cameras.) The ND filter suppresses this
phenomenon and gives better recording results.
