When using the X100, it's important to note that when utilizing its hybrid viewfinder in optical mode, there will be some degree of parallax error, especially when you're closer to the subject, as the visual disparity becomes more significant. Fuji has consistently denied that the X100 is a rangefinder camera, but hey, its optical viewfinder clearly functions like one! Another reason I like the X100 is its appearance—it looks so much like a Leica! After all, Leicas are generally out of reach for the average person!
