[Gain]
The amount of amplification of the video amplifier is set as either gain (dB) or ISO sensitivity. [Gain (dB)] and [ISO] are
automatically switched according to the type of camera.
[Gain (db)]
The value can be changed by moving the slider knob or clicking
or
. Also, this value is automatically adjusted
when [Auto] is turned on.
[ISO]
The value can be changed from the available options. When setting sensitivity, 1/3 steps or 1 step can be selected as the
increment. The value can be changed by moving the slider knob or clicking
or
. Also, this value is automatically
adjusted when [Auto] is turned on.
Note
• Increasing the gain may cause a slightly grainy screen. Also, irregular colors, white dots, and vertical lines may appear on the screen.
• In infrared shooting, [Gain] cannot be set.
[Iris]
Adjusts the iris (aperture) according to the brightness of the subject. Move the slider knob or click
or
to change the
value. Also, this value is automatically adjusted when [Auto] is turned on.
Note
• The aperture value that can be set differs depending on the zoom position. Reference aperture value is displayed on the screen.
• By changing the depth of field and blur the background or surroundings to make the subject stand out, set a smaller iris value, and to
keep everything from close objects to far-away objects in focus, set a larger iris value.
• If the iris is narrowed down when shooting in a bright location, this can cause blurring. It is possible to prevent blurring by adjusting the
shutter speed or ND filter and opening the iris.
• If a lens abnormality (lens not mounted, lens malfunction, etc.) occurs when using a camera that supports interchangeable lenses, the
[Iris], [Zoom] and [Focus] features are restricted. Also, when lens switches ([Iris] [Zoom] [Focus]) are set manually, those features
cannot be used.
• When [AUTO] of the iris setting is turned off, the aperture value of Auto is taken. It does not restore to the aperture value set before
[AUTO].
• In infrared shooting, [Iris] is fixed open.
[ND Filter]
The ND filter allows to open the iris for a video with shallow depth of field even in a bright environment. This is also
convenient for avoiding blur caused by a small iris when narrowing down the iris.
Move the slider knob or click
or
to change the value. Also, this value is automatically adjusted when [Auto] is turned
on. The slider or [Auto] may not be available depending on the model.
Note
Changing the ND Filter settings in certain shooting conditions could generate some slight change in coloring. In this case, it is effective to
set the white balance when shooting (P. 25).
• About Shooting with Slow Shutter
By setting the [Shooting Mode] to manual, shutter priority AE to set a slow shutter speed, or setting it to low light, it is
possible to shoot the subject brightly even where the light is insufficient. However, depending on the scene or the
subject, the following may occur.
– Noticeable residual image from moving subjects
– Deterioration of image quality
– White spots on the screen
– Autofocus not functioning well
