Had my HV20 for 10 days now, it's replaced a Sony HC3 HDV cam.
Love it in general - noticably better PQ than the HC3, also the OIS works better than the Sony's EIS.
Don't like the chromatic abberation either - it's quite noticable on some shots.
Actually the crummy little zoom lever works quite well if you have a steady hand/finger - you can get some really slow crawls - around 25sec for full zoom - that's nice - the HC3's zoom lever is much worse than the HV20 - totally uncontrollable and only 12 secs slowest full zoom.
Oh and the audio - the built in mics are not too bad at all - good top end and separation - no good on a windy day even with the wind filter on but lots clearer than the HC3 which sounds very muffled in comparison...
A great little cam all round - but my ideal cam would be a (non-existant) HV30 - the HDV version of a GL2 - a bit bigger with more buttons/manual control and a 20x zoom - wonder when this will happen?
