How to stop lens steaming in Miami

Hey all, I'm working on a job in Miami and have just gone out to do a few tests shots and found the lens had completely steamed up. I cleaned the front lens but despite this the picture is still completely blurred. I've bought it inside and still it is blurry. Is it possible that some part of the inner workings of the camera have steamed up.

The weather is incredibly humid, your drenched in sweat just standing around.

Any ideas what could have caused this? I need to start filming proper tomorrow and am now slightly worried.

Really appreciate anyones help on this.
 
I have just searched for 'fogging' and found the answer. Having the camera in air conditioned rooms means it takes about an hour for the camera to adjust to the temperature. That's frustrating! I assume that it given enough time de-mist?

Thanks
 
Keep your camera out of air-conditioned environments overnight. Also, you can purchase desiccant gel packs from people like Pelican to keep in your lens cases. The desiccant is not a 100% guarantee against condensation. The surefire method is to keep the camera from getting cold and too dry overnight.

The rapid change in temperature and humidity combine as you uncase the camera outdoors, and the moisture in the air is immediately attracted to the cold surfaces (e.g., glass, metal) like the water droplets that form on a glass of iced-tea.

Is the same true going to other way. From humid to cold?

Also how long does it usually take for the condensation to go away?
 
No need to purchase desiccants, just go to a shoe store or clothing store and ask an employee. They tend to have a box of the ones that fall out from their clothes or shoe boxes behind the counter.

The time for a lens to acclimate depends mostly on the relative humidity. In Houston it usually takes about 5-10 minutes from shooting indoors before I can start shooting outside. On set, since the air conditioning should be off you shouldn't have to worry it about waiting for a long period of time when going between indoors and outdoors. I keep my camera in the case with desiccants overnight and I put the case in a closet or a warmer room if there is one.
 
We had several F900s totally lock-up for an hour (factory fault default) during DriverX production. We found that pre-rolling the tapes prior to removing the cameras from the air-conditioned storeroom at the track in Darlington did the trick, though the front element of the glass still fogged for about a half-hour.

In Texas, we and had a DVX100a fog internally for about a half-hour in Houston and even longer in Brownsville. Bad things happen in Brownsville, TX.

Once we figured out the air-conditioning connection, we didn't have an issue for the rest of our two week documentary in Central America.
