I have not personally used Zeiss bins, except to borrow them once in a while,
so this particular bit of "evidence" should be considered with that in mind.
Once I was on a "traditional commercial birding tour" which included a few
nights at a jungle lodge on a peninsula on a lake in the Peten in Guatemala.
It was relatively humid, but not rainy. The leader used 10x42 Zeiss with
what I suppose could be called internal focusing (if I remember correctly the
front lens moved in and out while you turned the wheel.) One morning his
bins were badly fogged up, internally, and he had to borrow a spare from a
fellow on the trip. Of course, they could have been old, although they didn't
look beat up.
