Don, I missed the thread where you explained why you changed to the Ricoh GXR. Can you direct me to where I can find that explanation. Not that you need to explain yourself, I just assume that you did. Perhaps I am assuming wrongly. I love the interface on the GXR. That above all causes me to keep mine. Yes, the IQ is great but so is the IQ of other cameras I have let go. I have not tried the zoom lenses. If they are good enough maybe I would not need the X10.
