Ok I live in South Florida and upon exiting an air conditioned environment to go outside in the heat/humidity my camera lens foggs up something terrible. (So do my glasses but they clear up on their own rather fast but the camera lens doesn't). I mean it is bad and you can actually see condensation forming on the lens.

Is there a simple solution for this/ Thanks.


A camera.
Trinkets galore.

As per CorruptedPhotographer stated in another thread "Before going to the outside, put the lens in a ziplock bag and leave it outside till the body temperature of the gear changes to the outside temperature. When it does, take it out and use it, this way it will not fog up because there is no sudden change (to the gear) temperature wise."

Thinking of getting a new gear, not sure if it's the right choice ?

maybe try leaving it in the trunk (where air-con is limited or not at all) instead of inside the vehicle where the air-con is blowing.

Hi, try searching on the net for dew heaters or dew bands, I use them in my other hobby of astronomy to stop dew forming on the optics of my telescope (just the same as the fog you descibe), but have also used them on camera lenses when taking long exposures at night, either that or use a small 12 volt powered hair dryer (which I also use)

Put the hair dryer on the lowest setting and blow it at the glass, to kinda warm it up

Put a filter on the lens. Then take some white liquid hand soap. VERY little amount and buff it onto the filter. The haze will go away after you buff it a bit. If you have a cheap filter that fogs in between then take your own risk buffing soap onto the lens.

I had to do this to my lenses in the caribbean since they would fog so badly in the humdity. Without it I got very "english" looking shots when it was too humid.

Motorcyclists and hockey players use this old trick to keep their visors from fogging.


people will always try to stop you doing the right thing if it is unconventional
Full frame and some primes.
