Hi Paul - welcome to the forum. If you want pro XLR mic inputs, manual audio level control, a headphone jack, autofocus, a power zoom, an articulated LCD and moire-free images - save yourself a few $ and get the
$1950 XA10.
If you want "cinematic shallow depth of field" - and are prepared to deal with moire, the lack of XLR inputs, no headphone jack, no autofocus in video mode, manual zoom only, a 12 minute shot duration limit and a fixed LCD, get the
$1990 5D Mark II and be prepared to shell out more money for lenses and external audio recording equiment.
Since you're coming from camcorders, I think you'll be most comfortable with the XA10 - or perhaps choosing a less expensive DSLR. DSLT or DSLM such as the
$836 Panasonic GH2.
Hope that's helpful,
Bill
