Just kidding. It's also way too big (77mm filters!), especially when compared to the 18-55, which is just one stop slower at the long end. I wish they would update the 18-55 with weather-sealing...
I doubt that Fuji will sell a lot of these if they don't add an in-body IS to their cameras (what I definitely want them to do! With Oly E-M5II-style pixel-shifting please! ).
