[Matt Devino] "looks about 3 stops more sensitive"

THREE STOPS? Forgive me for doing a spit-take here, but -- three stops? I just spent a couple of days with both of these cameras side by side, and I did have a waveform monitor and a vectorscope and my DSC charts, etc., and sensitivity is one test that I ran. When both cameras were configured to deliver a fundamentally identical image (i.e., comparable gamma, comparable color rendition, both in 1080/24p mode, both in 180-degree shutter) the EX1 was more sensitive -- by 1/2 of one stop. 0.5 stops. Not three stops! One half of one stop.

Granted it is more sensitive, but not by the Paul Bunyan-sized tales that are being spread about it. It is much cleaner in noise though. If you push the EX1 to 6dB, it's about as noisy as the HVX is, so if you want a noise-to-noise sensitivity comparison I could see claiming 1.5 stops. But three stops is just... not realistic.
