This has been one of my complaints with these nifty-and-surprisingly-

good-but-not-perfect "small" 3-CCD Mini-DV camcorders. Not so

much that a fairly slow zoom rate is not available (the VX2000 is

OK for this), but that the start/stop is abrupt. Using the manual ring,

you can start/stop the zoom progressively (so the electronics are

there to do this), but you cannot maintain an even zoom speed

over much range with it. Using a Lanc controller does not help

(though the Varizoom permits accelerations/decelerations, but

not to/from 0) since through it, there is a minimum zoom speed

that is the same as the one offered by the good rocker on these.

Too bad, since the ring action indicates that it might have been

possible to have wired the Lanc and rocker to have had a lower

available zoom speed at least (but both [except with the Varizoom]

offer incremental speed changes, which also do not look good).

BTW, I generally combine a zoom with a pan/tilt when shooting,

and the additional picture motions can help conceal the zoom

start/stop limitations. Also, it is unwise in this medium to try to

"zoom in post", as someone else suggested - the resolution does

not permit doing this well, and even slight zooms within the picture

result in undesirable artifacting in addition to noticeably lowered

overall resolution. Ah, well, what price convenience...;-)
