The X-Pro1 and the X-E1 are great cameras, but when it comes to street photography, I keep coming back to the X100. It's a couple of things really, like the 23mm lens (35mm full frame wise) and the extremely quiet leaf shutter. The 35mm and the 18mm are great lenses, but for me, on the street, I like the classic 35mm angle of view. But then the title of the blog might have given that away!
