Last year the Gf and i took a carribean cruise..
It was super mega hot and HUMID... mean while the room we were in was nice and cold because of the a/c of course..

so there were some mornings where we would wake up at the moment where were pulling into a beautiful port ,, so of course i grab my camera and run out onto the balcony to take some pics only to be unable to due to the fogging up ..
this would happen thru out the trip , and became quite annoying .. also it caused the rubber grip part of the lens to become loose.. i assume the extreme change in humidity level softened the glue.. it has dried back up and stays in place although the edges arent tucked in, in all places like it used to be.. not such a big issue now but when i was there it was annoying and a little disappointing considering it was a 2200 dollar lens ,, you'd think they'd use better glue, or maybe my expectations are too high

so , is there a practical away around the condensation? something that would allow me to use my camera without waiting 20 minutes for it to acclimate ?

any tips would help

Leave it on the balcony, or start getting up 20 min. earlier so you can take it out there before you need it. Or get used to shooting from inside the cabin through the glass. Only way to keep from getting condensation directly on a cold object when bringing it into a warm environment is to wrap it in something so it can come to the new temperature gradually.

Place the equipment in a Ziploc while in your room to keep the moist air away when you step outside and let it sit in the sun for a minute or two. The sun will heat up the equipment past the dew point in a very short time. Leaving it in your bag is actually not that great of an idea as the bag is a decent insulator greatly increasing the time it takes to warm up.

The issue is not 'change of humidy'. the issue is that the relatively cold equipment causes condensation of moisture suspended in wam air. So if equipment is kept in plastic bags while it wams up, when it is exposed to warm air the moisture will not condense on its surfaces.

I tried the zip-lock bag with a sachet of silica gel during our last cruise. That did not work by itself. The only thing that worked was to allow the camera to heat up to the outside temperature before removing from the bag. You just have to wait a few minutes for the condensation to go away.

It doesn't have to be to the outside temperature, just above the dew point though in very humid places they are usually pretty close unlike in the desert where the temperature difference can be huge with no condensation.
