An October with decidedly unfavorable weather conditions and many humid evenings, here in  south of Italy.
The layers of air laden with particles of water at low altitudes (when humidity is deposited everywhere), unlike the stable fog at high altitudes, make the shots originally quite noisy and not sharp, even if aire is relatively stable.
In fact, the second situation seems better than the first, with the same turbulence and image stability. The low-lying humid air layer appears to have worse effects.
Disadvantaged in this period are the SCs, due to the fogging of the sheet and the deposit of residues on it even after drying. The hoods certainly help.
It is essential to identify the right FPS and the right exposure and gain values, which is not exactly simple.
Any suggestions are welcome.

Nice looking set of images, despite the condtions.
