"What the test showed more than anything is that these two little gems both create images of equal quality. Based on early web JPEGs from the X100, which appeared a little soft, I was prepared for the X100 to come up short in detail and sharpness but that was simply not the case. Surprisingly, the X100 Fujinon lens was just as sharp and in a couple of the photos I see it best the X1's Elmarit! Specifically in the b/w image, the X100 resolves much more detail on her face. "

"All in all, the test made me a believer in the Fuji X100 and its lens. That comes from someone who reviewed the X1 last year and raved about its image quality ( http://www.precision-camera.com/community/2010/06/leica-x1- –-back-to-the-future.html). Fuji did an amazing job."
