I agree the Panasonics audio are definetely the best.But if your videotaping a loud concert(especially if your down in front)You'll overload the cameras preamp anyways.
On my Sony VX2100 which has manual level control and vu metering i recorded a band from the front row and showed my levels being good at around -12 and the audio was distorted cuz the internal preamp couldn't handle it.I also ran my Sony HiMD with DPA 4061's and that turned out perfect.So to be safe i would always run a seperate audio recorder,and use the video's audio as a guide to synch up your good audio later in post.
But if you doing low profile video from far away the cam will prolly suffice alone,but still won't be stellar.
