Foggy lens - any tips?

[marinapj]

Any tips on how to prevent our camera lens from getting foggy when getting out of an air-conditioned room and into the humid Florida weather?

Thank you!

The lenses will definitely fog up pretty quickly when going from an air conditioned room to the outside Florida humidity.

My camera instruction booklet says to keep the camera and lens in an airtight bag until it's the same temperature as the outdoor one to avoid condensation.

I would imagine FOG-x by Rain-x would work.... its just the cold glass meeting hot air, you can avoid that by keeping the camera in a bag and in a warmer place where you're staying.

Keep it in your bag, sealed shut. If you have a balcony or a safe place to stick it while you get ready in the am (even the bathroom works sometimes), put the bag out there until you're ready to walk out the door. I also collect those little packets that come in medicine bottles, electronic boxes and toss a few in my bag to (wishful thinking ??) absorb any moisture in the bag.

And I would not put any chemicals like Fog-X or Rain-X on your lens! I see what it does to my windshield and to have to deal with the smearing on my lens-no way!!! On that note, be sure to bring along something to clean your lens with just in case. I have a Lenspen and microfiber cloth in my bag.

I too leave the bag outside on the balcony under a chair before heading out. It is the only way to avoid fogging.

I read an interesting tip that I haven't tried yet, but sounds like it should work. You can warm the front element of your lens using those disposable hand warmer packets to avoid the fogging if leaving your camera outside for a bit isn't possible.

Whatever you do, be extra careful to make sure the camera is close to the ambient temperature before a lens change because you risk the rear element and mirror being the next to fog!
