Still, is the Leica IQ is better than off of the above cameras? Or has it been eclipsed by newer cameras?
I would recommend that you browse the forums here, search pbase.com for images from both cameras, and download the LFI app check out the X1 Mastershots. I have, and there is no question in my mind that it is at an entirely different level than any of the above cameras when it comes to IQ and distortion. It's certainly not the ideal camera for everyone, but I'm sure that I'll be buying it (or possibly the X2).
