Camera Settings
Sets the camera settings.
[Camera Mode]
The camera offers five camera modes.
[Auto]
The camera controls the exposure by automatically adjusting the iris, gain and shutter speed.
[Tv] (shutter priority AE)
Set [Shutter Speed] to match low light conditions or fast moving subjects. The camera will then automatically set the
appropriate aperture and gain to obtain the best exposure.
[Av] (aperture priority AE)
Set [Iris] (aperture) to control the depth of field. The camera will then automatically set the appropriate gain and shutter
speed to obtain the best exposure.
[AGC] (automatic gain control)
You can set [Shutter Speed] and [Iris] (aperture). The camera will then automatically adjust the gain (the sensor's
sensitivity) depending on the brightness of the subject.
[Manual]
You can adjust [Shutter Speed], [Iris] (aperture), and [Gain].
Note
When the camera mode is set to a mode other than [Manual] and the brightness changes, exposure adjustment may not be smooth.
[Iris Increment]
When the camera mode is set to [Av], [AGC] or [Manual], you can determine the aperture value increment used in adjusting
the aperture from [1/2 stop], [1/3 stop], and [Fine]. If you select [Fine], the actual increments will be smaller than 1/3 stop.
Note
When using a compatible EF Cinema lens, enable automatic adjustment on the lens.
[Iris]
When the camera mode is set to [Av], [AGC] or [Manual], you can adjust the aperture value.
Moving the slider to the right narrows the iris, making the video darker. Moving the slider to the left opens the iris, making
the video brighter. Available aperture values will vary depending on the lens attached.
To adjust the aperture from the camera, you will need to enable automatic adjustment using the controls on the lens.
Required settings vary depending on the lens. Refer to the following table and the instruction manual of the lens used.
Important
• If [Shutter Speed] is set to 1/4, 1/5, or 1/6, one-shot AF is not available.
• Be aware of the following when adjusting the focus:
– If you operate the zoom after focusing, the focus on the subject may be lost.
– When adjusting the focus, be careful not to touch the front of the lens or moving parts on the lens except for the focus ring.
• When adjusting the focus with one-shot AF, also be aware of the following:
– Autofocus may not work well when high [Gain] levels are set.
– Autofocus may not work well when [Gamma] is set to [Wide DR] or [Canon Log] in [Custom Picture].
– The point where the camera focuses may change slightly depending on shooting conditions, such as subject, brightness and zoom
position. Check the focus before resuming shooting.
• With some EF lenses, the camera may take longer to focus automatically or may not be able to focus correctly. Visit your local Canon
website for the latest information.
• When attached with a lens which does not support one-shot AF, focusing can only be performed manually. For information on lenses,
please refer to "Setup Guide".
• The focus position may shift in an environment with large temperature changes. Set the focus again and check whether the focus is
correct.
