You asked "what would you get", and I would get the 70-200 because I love that focal length range. Great for portraits and a nice compliment to the 100mm macro for closeup nature photography. The great IQ of the 70-200 is a bonus.


Of course, what matters is what *you* should get. If you had nothing, I would say the 24-105 is more important. But you have the 18-55 already, and you have no long lenses. The 70-200 gives you something different from what you already have, while the 24-105 is just an upgrade.


If I were you, I'd get the one I was more excited about, and not worry about being sensible. Either choice is sensible.
