I have not even got around to powering these cameras so no idea of lens specification, except that they are BIG !  :-DD

Simple - you have a narrowing of just over 4x from the pixel pitch and 2x from the smaller sensor.  then some small angle (un)approximation stuff going on. 9% of the original field of view.

If it was a microbolometer I fancy it is an f/1 lens - or not far off.  So might well be another 150mm F/L ? = 0.55 °
If it was a cooled sensor then the lens is going to be nearer f/4 - putting the F/L up to 600mm   :scared: =  0.14°
