► Select HOME > EI > Iris.
► Rotate the jogwheel to open or close the iris of the EF lens. Press the jogwheel to toggle between
full stops and sub stops.
Info: Sub stop precision depends on the lens type and is automatically set by the camera.

Enable Lens Mount
You can disable the LDS contacts of the lens mount. Usually this is not necessary, but it can be helpful
when e.g. lenses with faulty lens data are used. Please note that as soon as an LDA lens table is
activated, the LDS contacts of the lens mount are switched off automatically. There is no need to switch
the mount off manually when using LDA lens tables.
► Select MENU > Lens & ECS > Enable Lens Mount to enable/disable the lens mount contacts of the
lens mount.
A disabled lens mount is indicated through the LDS icon on the HOME screen as well as in the
Status Info.
