Well done. You ask of the 16-50 XC
I got mine with my first Fuji ILC the X-A1. I probably WOULDN'T have purchased it at all, but I couldn't buy the camera without it. I'm glad that's the case because it is one of the lenses I use most often (other than the 10-24/4). The 18-55 is a great lens, but the advantage of those extra 2mm of wide angle and the excellent image quality and OIS of the XC lens make it a STEAL for the price. The f/2.8 is wonderful as well as I'm sure the 16/1.4, but the 2.8 is a behemoth the likes of which I left behind with my DSLR mirrors and the 1.4 is a much more expensive prime. For the price, size, wide angle and quality, the XC is hard to beat even though I have the much 'nicer' lenses on hand as well.
