Important
• When using a compatible EF Cinema lens
– When you change the aperture value from a position of fully open or fully closed iris, multiple adjustment operations may be
required to change the iris.
• The aperture values set and displayed on the Setting Page are approximate. Use them only as a reference.
• When using a compatible EF Cinema lens, enable automatic adjustment on the lens.
[AE Shift]
You can compensate the exposure obtained during automatic exposure (camera modes other than [Manual]), in order to
darken or lighten the image. You can select a level from -2 EV to +2 EV (in 0.25-EV increments).
[Shutter Speed]
If [Camera Mode] is set to [Tv], [AGC], or [Manual], you can fix the shutter speed.
Set the shutter speed based on shooting conditions. For example, you may want to set slower shutter speeds for darker
environments.
Setting values available for 59.94 Hz/29.97P are as follows:
1/4, 1/5, 1/6, 1/7, 1/8, 1/10, 1/12, 1/15, 1/17, 1/20, 1/24, 1/30, 1/34, 1/40, 1/48, 1/60, 1/75, 1/90, 1/100, 1/120, 1/150, 1/180,
1/210, 1/250, 1/300, 1/360, 1/420, 1/500, 1/600, 1/720, 1/840, 1/1000, 1/1200, 1/1400, 1/1700, 1/2000
Important
• When shooting under artificial light sources such as fluorescent, mercury or halogen lamps, the image may flicker depending on the
shutter speed. In such case, set [Flicker Reduction] to [Enable] to have the camera automatically detect and correct* flicker (P. 85).
* Depending on the shooting conditions, the camera may not be able to reduce the flicker.
• Alternatively, you may be able to avoid flicker by setting the shutter speed to a value matching the frequency of the local electrical
system: 1/100 for 50 Hz systems, 1/60 or 1/120 for 60 Hz systems.
[Auto Slow Shutter]
Determines the shutter speed used when the camera mode is set to [Auto] or [Av]. When this setting is set to [Off], the
camera will not use shutter speeds slower than the frame rate currently used.
This will reduce blur on moving subjects in dark scenes.
[Gain]
When the camera mode is set to [Manual], you can manually adjust the gain to change the brightness of the image.
You can select a value in the range from 0 to +75 dB (in 3-dB increments).
Important
• When high gain levels are set, the picture may flicker slightly.
• When high gain levels are set, bright red, green or blue dots may appear on the screen. In such case, use a faster shutter speed or
select a lower gain value.
[AGC Limit]
In camera modes other than [Manual], the camera will automatically adjust the gain. In such case, you can set an automatic
gain control (AGC) limit to prevent the camera from using gain values above the preset limit.
You can select [Off (75dB)] for no limit (maximum gain as given in the parenthesis); or a maximum gain level from 36 dB to
75 dB, in 3-dB increments.
[White Balance]
The camera uses an electronic white balance process to calibrate the picture and produce accurate colors under different
lighting conditions. There are six methods of setting the white balance.
[Auto]
The camera constantly adjusts the white balance automatically to achieve an optimal level. The camera will adjust the
white balance if the light source changes.
