Has anyone already noticed, that Air 2 S can only be operated at a temperature 32°F (0°C) and above and not like the Air 2 at 14°F (-10°C) or even at a lower temperatur as proved last winter.

Hi, MySky. Thanks for reaching out! The DJI Air 2S uses a new camera sensor, and more vision sensors are added. In consideration of overall performance, DJI Air 2S is temporarily not suitable for environments below zero degrees celsius.  

Now thats a surprise,   I guess people visiting Iceland may get caught out by that.

Indeed this is a surprise.  I think there is more to it than a sensor difference between the 2 that would effect the operating temperature range.
