Been using S270E and Z7 alongside XDCAM HD for over a year now.
Don't like them. Alas, one reason was the bundled Zeiss, which
is getting replaced, but too late for us. When we discovered
the CMOS had problems with florescent lighting we were told by
Sony Support that noticeable scrolling black bars on the screen
were a 'feature of the camera'. They later retracted that and
suggested shutter tweaks -- which worked for some office lighting
but not all.
