Leading the way: there is nothing better for X-E1 / E2-X / X-Pro1, etc. The fastest among the Fuji - lenses ... felt 5 times faster than the lame XF35, while almost as sharp (which is totally sufficient) and are adequate for most situations. Only in dark rooms, it has a disadvantage compared to the 35s. I have now - except in the evening), only the 18-55 here. Just buy it, especially as the price for this little marvel with the great Metallhaptik, the fast AF and the barely audible noise is more than fair!
