Hi,

Seems no matter what I do, when I go from inside to outside in the tropics my f/2.8 300mm and f/2.8 400mm are fogging up.

I'm also concerned about my 1DX and 1DXMKII

The ONLY solution I can see is leaving them outside but in the tropics, I'm worried about moisture again...

There are lots of solutions.

An inexpensive one is to put each piece of gear in a sealed ziplock bag before bringing it outside.  Once outside, allow the gear to warm up before opening the bag.   You will find that your gear no longer fogs up.

The reason your gear fogs up when you go outside, is that the gear is colder than the outside air dew point.

Do not put the gear back into the bags when you go inside.  You only need the bags when going from a colder environment to a moist warm environment.  You want to make sure the bags contain air from the colder environment.
