avoid HPX302... I suffered the "rolling shutter effect" while covering an event recently. There were strobe lights on the drummer and the artifacts were clearly visible.
My client even thought my video signal to the projection is loose.
Apparently Panasonic released an update for HPX302 but I have not tried it out.
The kit lens on the 302 also cannot make it in one particular area - It breathes too much. Can't do a simple rack focus without the lens zooming on its own.
