- because of the design of the X100′s shutter & lens, you can’t access certain shutter speed and aperture combinations. For example, you can’t use a wide aperture at a high shutter speed. The shutter speed is displayed in red in the viewfinder should you go outside the range that the camera’s shutter & lens design is capable of.
Final overview:
The camera is a delight in terms of its build and physical look and design.
The lens is superb as well, despite a tendency to flare easily with back-lighting.
Image quality is surprisingly good. I would say unexpectedly good. Check the review: Fuji X100 at a wedding where there is a full-res file shot at 6400 ISO.
The only downside is the menu system and some firmware / software quirks which affects its behaviour.
My final summary: Fuji really created a camera here capable of professional quality images, in a compact body. It’s a camera that is (mostly) a delight to use, and I can see how this specific camera will get a huge and loyal fanbase.
