A new one for me (I normally have extremes in temperature) -
Today I went out to shoot at a rookery. The humidity was extreme.
The front of the lens kept getting fogged up. Is there any hints that anyone can give me when this happens again?
To keep moisture from collecting on it place it in a zip lock bag wherever you are at and leave it in that bag until you get to your new location and the temperature has stabilized. This may take a fairly long time. Then when you leave repeat the process again.

Remember there will also be some moisture in the air that is inside the camera.
The problem is that taking a colder camera into warmer humid air can cause condensation on the camera. In summer taking a camera from cool inside A/C to hot humid outside can do this. In winter taking a camera from cold outside to warm humid inside can do this. Alfred is essentially saying keep the camera at the shooting temperature. Bill is saying put the cool camera in a plastic bag (get the excess air out of the bag) and let it warm up - the condensation forms on the outside of the bag.
Thanks everyone. During the winter I am careful to keep the camera in the bag going into and out of the car or house (leaving it in the bag until it warms up at the house/not using heat in the car when shooting from the car). I guess I didn't think this time. It was about a 20 minute hike to the spot and I thought that would be enough. I was there about 1-1/2 hours and had problems almost the whole time with the lens fogging. I am not used to this amount of humidity in North Dakota. I do have the desiccant paks in the camera bag and hope that is ok.
When headed out to a warm humid site you cannot keep your lens air conditioned the night before.... Cold to warm is death. Once you do it, point your lens to the sun, be patient, and wipe down the front element every few minutes....
