The new firmware fixes the following problem: “If the images are shot with ISO Bracketing mode when “QUICK START MODE”(*1) is set to “ON” and turn off the camera,the camera cannot be turned on again even with ordinary operation.“

There is also a new review by David Pogue from the New Yor Times: “Real photo devotees don’t see a fixed lens as a huge detriment. They see it as a limit that inspires compositional creativity, like the 140-character limit on Twitter. And on the X100, the lens is the equivalent of a 35-millimeter film lens, perfect for portraits and a nice balance for landscapes. If you know how to use aperture and shutter speed controls, no camera on earth gives you quicker and more direct access. “
