Keith, The answer is, yes.
From: Leica Camera AG - Photography - LEICA MThe new Leica M is the first ever M to feature Live View and Live View Focusing. This means that now, for the first time, images can be composed using the actual image produced by the lens – with complete control of depth of field, exposure, precise framing and focusing. Its large, high-resolution 3" monitor allows precise assessment of the subject seen through the lens. This opens up entirely new opportunities for M-Photographers that previously lay far beyond the limitations of rangefinder photography, like macro and telephoto exposures, or using the monitor as a viewfinder.
