Hi, note that Picamera2 is not related to any specific camera, it works with all our supported camera modules.
Neither Picamera2, nor libcamera that it is built on, actually mention ISO - because its meaning for digital cameras tends to be a matter of debate. Instead they deal only with gain.
On the Raspberry Pi, when you ask for gain, you will get analogue gain in the sensor up to the maximum that the sensor supports, and after that it will apply digital gain. The maximum amount of analogue gain that is possible will vary from sensor to sensor. You can find the maximum allowed analogue gain (after configuring the camera) as follows:
