Control limits: This function limits the travel of the slider at two predefined marks while
maintaining the full rotation of the lens. E.g. for quick iris racks.
Setup: Select the desired limit function in the slider limits menu. Assign a user button to
“Slider limits set”. Move the slider to the first iris mark. Press and hold the user button
assigned to “Slider limits set” and move the slider to the second iris mark. Release the user
button at the second iris mark. The selected limit function will be applied automatically. In
order to deactivate the limit function and to return to regular slider control, press the user
button assigned to “Slider limits set” again. A pop up menu indicates the status of the
limit functions being activated or deactivated.
Note: If you change the limit mode while a limit is active, the limits will be deactivated
automatically. You will then need to set a new limit range.
Note: Pre-marked iris strips do not work with slider limits.
Also, individually marked iris strips will not match the scales while these limit functions are
activated.
