The GX100 is based loosely on the legendary GR-D, the first compact with a prime lens. 24mm wide end with a converter to get down to 19mm, widest yet in a compact. But the cute bit is the optional electronic viewfinder which plugs in to the hot shoe. Brilliant idea and it flips up for discrete look-down shooting. Good street shooter. However, it is a small 1/2.5" sensor so 400 ISO and up is noisy. There's a price for small.
