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.

Fogging is caused by a difference in temperature.

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

Don't be--they are sealed.

Actually do be concerned.  They may be sealed, to a degree, but they are not airtight and the condensation that forms inside is due to the passage of humid air into the body / lens.  Although the EOS-1D Series have internal components and electrical connections that are to a degree protected against some moisture, they could eventually fail due to corrosion if subjected to this repeatedly.

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

Here is my question,

What period of time is safe to "assume" that all moisture is off all internal/external lenses and mirrors in the bodies... With the cameras sitting in the sun to dissipate moisture?

I'm sure even slight remanents and effect focus and electronic contacts... Thank you.

If your room in the tropics were at the same temperature as the outside, then the lenses would not fog !!
