The 18mm f2 is a damn good lens. It's just that if you lined it up with the 35mm and the 60mm it would come in last place. Sort of like winning bronze in the Olympics. With the quality of Fuji's optics, I see no reason to resort to third party glass unless you want a full time MF lens or a focal length that Fuji doesn't make yet. According to the roadmap we should see a pretty good selection of lenses by the end of next year. Really I'll be happy when they come out with the ultra wide. After that, I'm pretty much done.
