• If you set an assignable button to [Iris Mode] (A 105), you can press the button to toggle between the
[Automatic] and [Manual] settings.
• The aperture value may change in the following cases.
- While using the built-in extender or iris compensation function of an EF Cinema lens, when you switch from
automatic aperture to manual aperture.
- When the aperture controls on the lens are switched between automatic/manual mode.
• When using EF Cinema lenses that let you adjust the aperture gain, if the aperture gain is set too high, the
aperture adjustment may not be stable (“aperture hunting”), depending on the shooting conditions. In such
case, reset the lens’s aperture gain to its initial value.
