Doesn't look any different to a NEX-5n. It still has that rather unsatisfying softness to the image and the 'jello' is still there.
I am led to understand that the main drawback with the NEX series is that, despite having an excellent sensor, it is the amount of information that is discarded in order to write to the SD card that degrades the recorded image. This is why the GH2 hacks with their increased data flow are producing such stunning results. Mind you, the GH2 produces cleaner, sharper video than the NEX anyway.
Unfortunately, the GH2 appears to be in short supply - and overpriced if you can find one.
I am wondering if the NEX HDMI output is coming straight from the sensor. If it is then an HDMI digital recorder might capture everything and deliver properly impressive HD.
