Anyone with VG10 and NX70/CX700/CX760 etc. at DVinfo.net

I'm looking for a comparison of the VG10 with the kit lens against the NX70 or CX700/760. Specifically low light. With both cameras set at 1/30 shutter, wide angle with aperture wide open, and gained up to max (24dB on NX70, 27dB on VG10). If you could find a dark scene and just set the cameras side by side and shoot 5-10 seconds I'd appreciate it.

You need to be a little careful making that comparison.
The "kit" lens on the VG is a slow f 3.4
The lens on the CX cams are a fast f1.8
So, right out of the box, the CX cams will blow the VG away in low light, just based on the lens.

Not sure I would agree with this statement. The chip size, noise and light gathering capability of the individual chip will still trump the f stop benefits. With NX70U which I tried out briefly, the VG 20 is seemed much better in low light than the NX70U. I assume this is repeated in the CX line.

I've shot a lot of stage shows with a VG20 with kit lens beside a Sony CX550. The kit lens is very slow so the VG20 ramps up the gain a lot earlier and is visibly noisier, especially as you zoom in and the iris closes to f6.5. Fortunately the noise looks a lot like film grain and is not too obtrusive.

Incidentally, I also use a 3 chip Panasonic TM700 palmcorder for wide shots beside the other two and it often blows them away in terms of overall image quality.

That was also my experience comparing exactly the same cams- the VG 20 and the CX 550.
However, when I outfitted the VG20 with a 30mm f 1.8, the low light performance was outstanding.
The bottom line for me- I felt it was important to have the fast lens at least available anytime I was going to shoot low light with the VG.
