I am fully sold on m4/3 for my main system. But like in my 35mm film days, I liked having the Fuji fixed lens medium format camera around for high quality, high detailed landscapes. I that vein, there are 2 intriguing compact digital cameras that could fill that niche: The Sigma DP2 Merrill with the highly touted Foveon processor at 15MP (x3) and the Sony RX1 - the first full frame fixed lens compact. Price aside, I am interested if what people on this site think about the 2 offerings. Does a ASP-C Fovoen sensor best the FF Sony? Optics? Anyone here use the Sigma? I think both cameras will be unwieldy compared to the OM-D system that I use, and certainly not as versatile. However, like with medium format cameras of yore, with patience, the end result can be special.
