•If you set the AUTO LOCK switch to AUTO LOCK, other manually adjusted items (gain, shutter speed, white balance) also become temporarily automatic.
•As you shift the zoom from W (wide) to T (telephoto), the aperture value varies from F1.6 to F2.8.
zTip
•You can select the rotation direction of the iris dial
with [IRIS DIAL] on the 
(OTHERS) menu (p. 80).
•The iris has an important effect on the “depth of field,” that is, the focused range. An open iris makes the depth of field shallower (shorter focused range), and a closed iris makes the depth of field deeper (longer focused range). Use the iris effectively according to your purpose of recording.
Adjusting the gain
Adjust the gain manually when shooting blackish or dark objects if you do not want the AGC (auto gain control) to be activated.
1 During recording or in the standby mode, set the AUTO LOCK switch to the center position to release the auto lock mode.
2 Press GAIN.
The current gain value appears.
3 Set the GAIN switch to the desired position.
3 gain levels (H, M, L) are available. You can set the value for the respective positions with [GAIN SETUP] on the 
(CAMERA SET) menu (p. 59).
The default settings for each position are 18 dB (H), 9 dB (M) and 0 dB (L).
The larger the number, the greater the gain.
