For many of you this might not be terribly exciting, but I'm getting pretty excited for the Micro Four-Thirds System. The G1 was nothing more than a "look what we can do!", I expect much more to come of this in the next year or so. For those of you who haven't heard, the Micro Four-Thirds is a new system developed by Olympus and Panasonic that removes the mirrors in the dSLR, making it considerably less thick and slightly less tall, at the lost of an optical viewfinder. Here's a look at some specs for those of you who haven't given this much thought or looked at all. The final camera is the numbers of the Olympus E-420 subtracting the reduction in height and thickness of the Micro system. Length Height Width Canon G10 109mm 78mm 46mm Olympus E-420* 130mm 91mm 53mm Olympus SP-560UZ 116mm 78.5mm 78mm E-420 Micro* 130mm 85mm 33mm *No lens Note that their is no lens on either dSLR. Also note that new lenses on the Micro system are going to be smaller, so it is possible that a new Micro pancake lens could be smaller than the 24mm width of the current E-420 pancake kit lens. Thoughts, opinions? I'm looking forward to a dSLR that can fit in a cargo pocket comfortably!!!
