That's the point, isn't it. We used to have cameras that were not guaranteed to work in even moderately bad weather. Then there was a lot of raving over images obtained under conditions that were outside warranty. Now that materials have approved, people go whining about the folly of taking the same risks. The only thing camera improvement seems to spawn is ever more demanding customers.
