In terms of manual-focus control and smooth zoom

start/stops, this is true - but in terms of sharpness,

the VX2000 lens reaches diffraction-limiting around f4,

and is excellent even wide open (and it is also low in

flare and has good contrast) - so in terms of optical

quality only, there should be not a lot of difference

(though a MUCH sharper lens will give a bit more on-tape

resolution shot wider than f4...).

In terms of resolution, again there should be little

difference, since both are limited to 480x720 (or

about 540 TV lines horizontal), and the VX2000

approaches this limit fairly closely (with 520-530

lines at optimum stop). The larger CCD offers advantages

in tonality, though the difference between 1/3" and 1/2" chips is not great - and Sony uses "HAD" chips, with their

greater sensitivity (and, I think, slightly better color).

A bit of "advertising" before the shoot on "how good these

newer, smaller digital cameras can be" may get you past

this...

The better tonality of the larger camera can help here...

These formats are the same, in terms of video and audio

signal quality...

This can be very useful. You will likely see minor

differences, but these are easily corrected...

????

For any "set-up" work, manual auto levels are preferable,

as are proper mics for the job, but for many purposes,

the VX2000 built-in omni mic is excellent, as is the AGC...

With DV/DVCam, though, the headroom is non-existent, so

"pushing up the gain" while recording can have disasterous

results (better to do this while editing, so you can

reduce the peaks to avoid clipping...).
