BUT moving a sensor 1 1/2" at a constant speed is no big deal in this day of linear motors and electronic speed measurement. Tilting a sensor a couple of degrees as it travels is no big deal either. The disc drive in your computer moves a read/write head to a variety of positions in a 30 degree arc in a tiny fraction of a second. It is hard to believe that all the imaginative people in Solms couldn't come up with a way make a full frame Leica, at least for lenses 50 mm or longer, perhaps a digital M3. Reserve the M8 for wide angle fanatics. I'm still hoping for a digital back to replace the film inspection door on my M series film cameras. If one sold for $1000 or less I'd buy it in a minute. Leica, are you listening? If not, Epson are you listening? Larry Z
