Keeping fog off of lens when going from inside to outside

[quote=singleviking]If this problem is only on the surface of lenses or filters and not inside, a simple coating of "RainX Antifog"auto glass defogger might do the trick (simple $4 solution)... /[quote]
I'd be cautious on that...worry that it might react with lens coating. IMHO it's better to figure out a way to warm up the lens as suggested by others.

I am not a professional photographer but if I were, and I was getting paid for a job, I would damn well go to a shoot prepared for all contingencies---and that includes bringing all the necessary equipment. That would include bringing back up equipment that hopefully would not have to be used. Doing anything less is unprofessional, naive and downright unethical. If I were going to Mexico for my own enjoyment (?) I would not bring back up gear.

Lens coatings are not simple polymer wipe-on coatings like RainX is. The coatings that lens manufacturers place on glass elements is sputtered deposition similar to metal deposition coated onto window surfaces by electron beam or vapor deposition methods for reducing UV passage.
Besides, you only need to coat the exterior surface of the lens filter if you've already dehydrated the lens and camera since the threaded filter mount is enough of a seal for humidity egress to the lens surface for most A/C to exterior environment transitions. If there is some interaction from extended use of a polymer, then all you lose is the filter.

It doesn't take imagination: I'm doing it next week. I can't imagine lugging two cameras and extra lenses I won't miss.
The situation determines what makes sense. Your input was not an answer to the question posed. Fortunately some useful ideas were offered. Thanks to those who did so.

Speaking from decades of experience. I bring to each shoot one Pelican #1550 case, which contains 2 cameras, 2 flashes, 3 lenses, and accessories. I do not "lug around" this case, but take one camera/lens & flash. I keep my case close by.
It seems to me that you would be less intellectual and more practical & imaginative, being a Capricorn and being born the same day of the year as me.
I feel my input is a practical answer to solving the FOG question asked. Actually I always go on shoots with an assistant, so my solution is even more simplified, by having my second shooter already waiting inside. When going on a shoot it is wise to have a plan "B", rather than to only have one camera/lens to work with. I'm just saying.

Granted tsilva was somewhat rude. However, he or she did at least have a point that is worth discussing. How much knowledge and equipment is necessary to do a professional job? That might be worth discussing.
The same can't be said for what some of you have done castigating tsilva after he/she posted. Don't you understand that you are doing exactly the same or worse as what you are complaining about tsilva for.
If you really want this forum to be civil and stick to the question asked rather than run off on tangents then you need to be civil and stick to the topic at hand as well.
In no way am I supporting what tsilva said. It is after all quite likely that the individual in question had no idea of the problems with heat and humidity and thought they had the wedding covered.
You are quite right that it will not help her one iota to point out her possible deficiencies. But give me a break is calling someone a dick or arguably worse either civil or constructive.
It's not. It's rude and obnoxious and it has become a serious case of piling on. Civility is a two way street. If you want others to treat you with dignity and respect then you should do the same.

It's never ok to castigate someone asking for help. He did that, and deserves a reprimand.

See if the hotel has some safes at the check-in desk area for customers and if the area of that safe is not air conditioned. It is best to have the camera warmed either by non air conditioned air or by the hair dryer that someone suggested. Going from hot into cold should not be a problem. But as noted, the opposite is not true. Good lucky with the shoot.

He did deserve a reprimand, but if you look at the posts they called him names and ridiculed him. No one deserves that either.
That's the point. Some people on this sight are rude, but others claiming to be the voice of reason resort to name calling just because someone else has a different view of the world than they do.
Look at all the crap that was said about tsilva here and tell me it's not as bad as what he said. It's worse. If you want people like tsilva to be more polite than reprimand then kindly and let it go at that. Don't call them names and resort to doing exactly what you are complaining about him doing.

tsilva deserves the UHH's worst-offense-punishment for being rude to a fellow poster: 40 lashes with a wet noodle, no chianti.
