Fog coatings for lens?
May 28, 2017 14:18:22 #
So often I am indoors, air conditioned in God Blessed Texas, and need to immediately take pictures outdoors. Depending on heat and humidity, the whole camera will fog, lens especially. I do not always have 10 mins to leave it outdoors before I need it. Often, its pics inside, immediately walk outside and pics again. Does anyone have any tips for dealing with the fogging issue?

Put a small light bulb, maybe ten watts, inside a cheap styrofoam cooler. Experiment with different size bulbs and find one that keeps the interior at aboout 90 degrees. Store the camera in the box when not in use.

There is another option you might want to try. There is product made by the Rain-X group to prevent fogging of mirrors, for instance in a bathroom after a shower. I can't recall its trade name but I'm sure you can find it on their web site.
I would apply it to a standard UV filter (both sides?) and screw that treated filter onto the front of your camera lens. Can't say for certain if it'll work in your situation, but the product does work very well in preventing condensation from forming in the house. It should do absolutely no harm to your lenses so I would give it a try.

Buy & have with you PHOTOGRAPHIC lens tissue to use to resolve this problem.

Use your main camera indoors and your backup camera outdoors.

Rain-X does not prevent condensation; it prevents it forming in little drops and makes a film of water instead. That film of water may be uneven, and that is not good for image forming.

I don't think keeping a camera stored outdoors is a very good idea.

I also live in Texas but have never experienced fogging of my lenses. You might consider placing the kit that you will be using for a day in the trunk of your car an our before you leave the house. Hopefully, your car is in your garage. I would never leave my camera equipment in my trunk unless it was in the garage.

To prevent fogging of goggles, skin divers use a little saliva on their glass. Get a standard UV filter out of your camera bag, spit on it and wipe it around. Attach "treated" UV filter to the front of your camera lens. It'll cost you nothing and it may even work.

Rain-x made an anti-fog product that I never had any luck with. I'm not sure if it is still made.

I believe that Rain-X will eventually be problem. This link gets you to an article on the subject. The article has a link elsewhere as well:

I am not sure the coated filter fix will work. If the entire camera is in a cool environment and is taken into a damp warm environment won't all the cool surfaces get condensation? I can't address the issue of whether the internal lens surfaces would get condensation if they were cool but effectively sealed by the lens construction. I live in a warm, dry environment and have never had to deal with condensation on my lenses, even in the Sierras in winter.

Lemme clarify my post. I tried this on mirrors and windows, as I live in high humidity, with no luck. My equipment climatizes.
