Focus
Required settings on EF Cinema lenses and broadcast lenses
To adjust the focus from the camera, you will need to change the focus mode 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.
Manual Focus
Focus manually using the focus ring on the lens.
1 Select > [ v Camera Setup] > [AF Mode] > [One Shot].
• On an EF lens, you can set the lens’s focus mode switch to MF. On a compatible EF Cinema/broadcast lens,
you can enable manual adjustment on the lens.
2 Turn the focus ring to adjust the focus.
NOTES NOTES
• With some EF lenses, you may be able to operate the focus ring even when the focus mode switch is set to
AF.
• If you operate the zoom after focusing, the focus on the subject may be lost.
• If you focus manually and then leave the camera with the power turned on, the focus on the subject may be
lost after a while. This possible slight shift in focus is a result of the internal temperature rising in the camera
and lens. Check the focus before resuming shooting.
• 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 an optional RC-V100 Remote Controller is connected to the camera, you can adjust the focus with the
remote controller’s FOCUS dial. At default settings, turn the dial right to focus farther and left to focus nearer.
