The transformation from film to digital required some fundamental changes, of course. These are most noticeable on the camera back, which has a bright, 2.5-inch, 230,000-pixel LCD screen surrounded by 10 buttons and a control wheel. (As with most D-SLRs, the screen isn't "live," so you use it only for image playback and menu navigation.) This simple layout provides immediate access to the top level of the onscreen menu, allowing you to check and change most settings quickly. The more familiar controls are in their customary places: the shutter-speed dial, shutter release, and frame counter on the top deck, the lens release and viewfinder frame line selector on the front. As usual with a Leica, these controls operate with a satisfying smoothness and precision.
