With some (all Sony camcorders), it may be useful to leave the

stabilizer on with a tripod to smooth its action - though care during

stopping must be taken to avoid framing "bounce-back". Some

stabilizers "swim" the image when a tripod is disturbed, and these

should be turned off...

Yes, and this may be where the OP's complaint arises. The VX2100

image is sharp enough to risk "mosquito" effects with fine textures,

and adding the WA, if sharp enough, can reduce some detail scale

to the point of causing these effects (but they would also occur

without the WA converter if the camera were drawn further away

[without changing anything else] to the point where the detail scale

was the same as it would be with it). Adding the WA converter in

itself does not cause problems with this, though - it is an accident

of scale. The fixed scan-line number (and resultant resolution limit)

can also cause scale-related differences in the image appearance,

but here, also, it is an accidental matter of subject-detail scale...
