Is it possible, that the FS700 + O7Q gets noisier when shooting in hotter equirements?
To me it feels like the footage we shot outside on a warm sunny day is noisier...
I can't comment on your specific application, but as a general statement about electronics, yes, heat causes noise.
[edit] From radio-electronics.com
"Thermal noise, like other forms of noise are random in nature. It is not possible to predict the waveform and therefore it is not possible to reduce the effects by cancellation or other similar techniques....
Thermal noise appears regardless of the quality of component used. The noise level is dependent only upon the temperature and the value of the resistance."
