I was in the SF store and purchased my X Pro1. Four hours later I was working on one of my personal projects in a very dark SF bar. The camera performed well and I was able to capture over 15 portfolio quality images on my use of the camera. Yes there are complaints about focusing the camera, but considering the Leica costs $7000 before a lens is attached and the speed of rangefinders, the Fuji is a steal. I do have experience with rangefinders as I have owned a Maymia 7II for 10 years. The real dissatisfaction comes with the Fuji service. I shoot two Canon 1Ds' Mk3's and am used to Canon Professional Services. Just remember the Fuji is not built like a professional Canon. Last week I bought the new 14mm to go along with the 35mm and I love them both.
Pros: Easy to Use, Lightweight/Portable, Many Useful Features, Good for Experts, Superior Build Quality, Sturdy/Stable, Quiet, Ergonomic/Comfortable
