Georgia summer heat and humidity; as you walk out the door of your air conditioned house (low temp and low humidity), you hit the wall of warm sticky heat. If your lens is not covered, the front element is immediately coated with a fine layer of condensate and this is what you get. I did not mind, as this photograph immediately recalls the experience of the heat & humidity for me, although I am not sure that the large amount of high edge flare would be always be read that way. But it works fine for me;- )
If you have a very inexpensive camera, you may find that the condensate is coating some interior layers of glass as well, and potentially your sensor. And that may take a while to come to equilibrium and for the condensate to evaporte away. This happened to a couple of inexpensive camera of the family members.
