Hi everyone

I'll be leaving the US to Vietnam in a week. As you all know Vietnam is a tropical country and usually very hot and humid. The average temperature and humidity at this time are 90 degree and 100%. I'll be riding on a lot air conditioned taxis and buses to shooting loactions, this is when I'm afraid of condensation forming inside my cameras and lenses when I step out of the AC into the hot and humid environment.

Many posts recommended to use a large zip-block bag to seal the camera and lenses for about 30 minutes to prevent condensation. A few posts recommended to just leave the camera and lenses in the camera bag and let the temperature inside adjust to the outside. I have a Lowepro Slingshot 300AW, and I have a couple of desiccant gel bags in it.

I know the zip-block method is the best, but what about the second method? I like it more because the time that takes me to the shooting location is enough for the temperature inside the bag adjust.

The posters that recommended using the zip-block method did not specify the size of their camera and lens combinations. I'll be shooting mostly with the 40D + grip + 24-70 f/2.8 or 40D + grip + 70-200 f/2.8 IS, do you think there is a large enough zip-block bag that can to hold those combinations?

What if I have condensation inside my camera and lens? What do I need to do? How long do I have to wait for the condensation to go away before I can shoot again? Should I get more desiccant gels?

Thank you everyone for your help and advice.
