GH2 - isn't sharpness too strong ??

I find it better yes, about noise it's maybe not extra, but simply we see it bigger because we're not downsampling the sensor size.
 
Come on just look at the awful noise in the second film on E-T-C, if you are talking about wide angle hand held filming it may give the results you like.

You realy find the image better with E-T-C http://www.youtube.com/watch?v=rje_9Dzta-k

http://www.youtube.com/watch?v=c7tecfq_830 we must own different cameras,those tests of mine show the extra noise with E-T-C

Are you zooming when etc is off to match the framing of etc on ? maybe if you have the camera in auto settings it uses higher ISO when you zoom ? I don't see noise difference from etc on or off. Not considerable differences..

I can make a similar test tomorrow, now my batt are charging. But from what I tried tonight I don't remember any visible difference.
 
c'mon, it's a less than 1000$ cam.. and it's limited, yes. same as GH13, and the Canons.
do what you can with it, and don't get such big hopes on a savior firmware/hack any time soon.
 
I find very hard to do what I can't, even if i would like to, but thanks for the suggestion ;-)
firmware ? the sooner the better.

On my HD tvs its very noticable,in the first link you will see the camera was set at the same zoom without E-T-C to compensate,but i am happy overall with my GH and what Roeiz says is true.

Robbie, could you perhaps show us a screen capture of the halos you're seeing? Thanks.

nothing here at the moment but they looks like any over digitally sharpened image in photoshop... to make it sharper the filter create more light difference between dark and bright pixels... very bad if there is ssome aliasing
 
I found that with the stock settings the GH2 has some haloing which is a bit less if you dial down the sharpening. The image looks sharper, but the pans are a bit choppy. The GH13 has the smooth pans, but looks slightly less sharp until you sharpen to taste.

...Robert, I processed your footage with the NeatVideo plug-in and rendered as 24 Mbit with the MainConcept AVC-MP4 CODEC. Here's a download link:

Roberts's Footage Processed with NeatVideo

It's obvious that the GH-2 version of the AVCHD CODEC is struggling with the mottled tones of the chair and the wall section on the left ( just too much tonal detail to render with only 24 Mbits ), but looking at the cleaned up footage it's really not that bad.
 
It could be the compression. One artifact of lossy compression algorithms is a trade off between softness and "ringing", which is essentially the same as sharpening. This is a tunable parameter by the algorithm designer. Panasonic may have opted for sharper. Upping the bitrate (lowering the compression) reduces the softness and/or ringing.

no I'm filming 1080i 25, the flicker is caused by digital sharpening.

It is one of the limitations of the cam. You see it when panning things that have fine deail. But overall, the IQ is very good. I suppose it is possible we are seeing some very fine grain that would otherwise not be visible--sort of a "too musch detail" thing. But some of what we are seeing is artifacts, for sure. A GH13 with the Blackout Powell patch will solve your panning issues, but for some things the GH2 is better.

I find with ETC it shines with a super sharp prime lens. I don't know why this is. The Panny 20mm works well and my Vivitar 90mm also. I just couldn't believe it the first time I tried it. Even my crappy 300 mm Sigma will pull some detail at whatever the equivalent is, like 1500mm, but the sharp primes work well. Noise wise, it is better than stopping down, for sure.
