The new HQ camera module is amazing and works really well using raspistill for long exposures. Using the picamera python library the camera locks with exposures above 10s (the maximum for the V2 camera). This is my code, am I doing something wrong or is the library not compatible?

camera = picamera.PiCamera()
camera.iso = 800
camera.sensor_mode=3
camera.resolution = (1024, 768)
camera.framerate=Fraction(1, 20)
camera.shutter_speed = 20000000
camera.iso = 800
camera.start_preview()
# Give the camera some time to adjust to conditions
time.sleep(20)
camera.capture('test.jpg')

  • Try sudo SKIP_KERNEL=1 rpi-update; sudo reboot that will get new firmware for the HQ camera.

  • I've been looking there and had drawn a blank. This thread looked promising but didn't fix my issue - raspberrypi.org/forums/viewtopic.php?t=276556
