It's been four months now since I've been shooting with the Fuji 16-55 F2.8 weather sealed beauty and I'd have to say it is my most used and favourite lens to date. Fuji makes awesome prime lenses as well and I currently have the 23 and the 35 but when carrying around the 16-55 it feels as if you have four prime lenses on your camera all at once.
I do have the 23mm F1.4 as well as the 35mm F1.4 and I love them both but when I'm on an assignment and have to shoot everything from portraits to landscapes and then food I reach for the 16-55 as it is the most versatile.
So what can you photograph with it? Almost everything: architecture, street, still life, portraiture, interiors, events.. What I love about it: its excellent image quality, solid build, weather sealing and it is fast. What I don't love: it is a bit on the heavy side, however coming from the D800 and a 24-70 it is still light in comparison. Also, because Fuji does OIS so well, I wouldn't have minded if they had included it on this lens.
Here are some image samples.
