I chose the 9-18 over the 7-14 ...

That's definitely the reason to go with the 9-18. It's a very nice lens. Incredible in what it does for the size. Add the 40-150 M. Zuiko and you've got a two lens combination capable of a wide range of photography that weighs nothing.

Compared to the size of the Olympus four-thirds 7-14mm f4 that I owned for around 13 months back in 2006-2007, the Panasonic 7-14mm f4 is pretty darn incredible too for what it does. The Zuiko is just so tiny.
