Honestly, im not impressed with the quality of the camera and the Fujinon lens. Images dont pop out to me even at F2, and the high ISO quality as presented on the Fuji X100 thread makes the images soft. Some say the softness gives the dreamy look of Leica lenses. But to each his own i guess - im not impressed.
Leica is fully manual focus, so I dont think its an apple to apples comparison, though they look similar. Unless you are talking about their compact range ie. Leica X1.
