NOTICE
•
When mirror shutter is active, the shutter angle is limited to 180.0 degrees.
Frame rates higher than 37 fps for 4:3, 6:5, and Open Gate, and higher than 48
fps for 16:9 reduce the shutter angle range further.
•
For frame rates higher than 30 fps, it is recommended to use a power source
with a voltage level of 18-35 V to ensure the mirror shutter is powered
sufficiently.
MIRROR PARK buttons VIEW and GATE
The camera left side Operator Controls have two additional function buttons labeled
VIEW and GATE. These buttons control the parking position of the mirror shutter.
A spinning mirror shutter can be stopped by pressing either of the two buttons.
Pressing the VIEW button will park the mirror in the optical path, enabling a live
preview in the optical viewfinder.
Pressing the GATE button will stop the mirror shutter out of the optical path, enabling
a live preview on the MON OUT and the EVF in case it is mounted to the camera.
Each button is accompanied by a blue LED that lights when the mirror is parked in the
respective position. When the mirror shutter is running, both of the LEDs will be active.
Pressing the GATE button while the mirror is parked in the VIEW position will move
the mirror shutter by 180.0° degrees into the GATE position.
Pressing the VIEW button while the mirror is parked in the GATE position will move
the mirror shutter by 180.0° degrees into the VIEW position.
To restart the mirror shutter, press both VIEW and GATE simultaneously.
NOTICE
After booting the camera, the mirror shutter is parked in the GATE position for
safety reasons.
When stopping, the mirror shutter always opens up the electronic sector gate to
180.0°, and closes down when it is restarted.
A live image on EVF and MON OUT is available when the mirror shutter is spinning or
parked in the GATE position. A parked mirror shutter will automatically start spinning
when recording is started.
When the mirror shutter is switched off, it is parked in the GATE position.
