That's funny. A bikini shoot on a hot and very humid cruise ship 8 years ago is the whole reason I dumped my Tamron and bought the Canon L equivalent. The front element didn't just fog, but all the internals too. My lens was useless for 2 hours. One of the other shooters had the 24-70L and he was fine after 5 minutes. I don't regret purchasing L glass since then. They are built like tanks and work in ANY environment or conditions.
I would get the 16-35 before the 14mm though. That 2 mm is not that big of a deal and the flexibility of the zoom is nice. Having said that, they are nowhere near as wide as 8 or 11...if you need that wide, there are only a few choices.
Temperature change has nothing to do with Canon L weather sealing, all glass, plastics & metals have a tendency to introduce moisture when introduced to extreme temperature changes, get the facts straight, The Cannon L series does not include or exclude temperature extremes that can produce moisture from Below zero 0 °C freezing to 100 °C Celsius boiling, actually many L lenses are not weather proof, in fact mold can grow inside any lens, Going from one extreme to the next, The Canon L lenses or more about Rain and water resistants... if that.
If you find yourself in extreme weather conditions it is recommended to slowly introduce your gear/lenses to the weather in a gradual way, I.E. Do not pull your lens from a warm Backpack into freezing conditions instantaneously.
FYI: This works both ways, Visa-Versa from Cold to Hot, Hot to Cold.
