12.3 Sensor Mode & Recording Resolution
The sensor mode determines the size of the area on the sensor that is read out. This affects the
maximum possible frame rate, the maximum data rate, and which lenses can be used. The sensor
mode naming is composed of the number of horizontal photo sites in “K” (a thousand) and the aspect
ratio used on the sensor.
The recording resolution is the resolution of the file that is being recorded in camera. Most of the time
the number of photo sites read from the sensor and the number of pixels recorded are identical, in
some other cases, as for instance in 4K 16:9 - 2K, the number of photo sites read out from the sensor is
larger than the number of pixels recorded into the file.
► Select Menu > Recording > Sensor Mode to select the desired Sensor Mode.
► Select Menu > Recording > Recording Resolution to select the associated Recording Resolution.
Info: Changing between Sensor Modes may require a camera reboot.
Info: The Recording Resolution is set automatically if a Sensor Mode offers only one associated
Recording Resolution.
