Now it is evident that A119 and A119S have the same maximum exposure time (shutter) in 60FPS and 30FPS mode and so, the same night performance (by the way, very good).
But for 30FPS it could be 2xlonger (1/30s instead of 1/60s) which would make the night pictures 2 x brighter in some conditions. Of course in that case with some blur impairment.
Please add this feature to the next FW version. For instance, with possibility to enable/disable from menu (because of blur impairment).
