Can anyone post some comparison pics of the V1u versus other cameras? Specifically, shooting the same subjects and using the same fstops, gain, etc. I'd be really interested. Specifically in situations where gain must be used. Surely someone out there must have a V1U and use it in conjunction with a different camera.

Have a look at this thread which compares the FX1 and FX7. It would give you some idea of how the V1 and Z1 stack up. http://www.dvinfo.net/conf/showthread.php?t=80594
