Interesting that the 2 most popular lenses are the 16-35 and 70-200. My guess is that they are the most useful for storytelling, and make an efficient combination together.
Most of the photojournalists and wedding photographers I know/have seen work use the 16-35mm and the 70-200 combo. I think it's largely because 40-65mm tends to be a kind of boring range. It's the normal range that we are all used to seeing. 16-35mm is great for capturing a subject and their environment, and 70-200mm is great for subject isolation (and getting closer when you physically can't). It's the combo I would choose to shoot with if I did photojournalism.
