I seem to have issues my my lenses fogging up constantly. I have to run the fan all the time or I get fog, and turning the fan on means it goes to full speed. Doesn't seem to matter if it is warm out, cold, inside or outside.
What are others doing to prevent fogging? I have been trying to see if I can find some kind of coating I could apply to the lenses to help prevent fogging & keep them clean.
