It was clear to me that after Zeiss entered the market with the ZF lenses and Nikon with the D200, I considered switching to Nikon. And now Leica is also in the mix, announcing the Leica D 14-50 mm F2.8-F3.5 for the four-thirds system. This not only brings the newly announced Panasonic Digi-SLR into play (which is likely based on the Olympus E330), but also the entire Olympus system. So another possible choice when switching? Especially since there are quite usable adapters for Contax-Yashica for the Four-Thirds system, so that I can probably continue to use all Zeiss lenses - unlike with Canon. Interesting is then also the image stabilizer and - probably inherited from the Olympus system - the ultrasonic chip cleaner in the body.
