Dpreview just posted the new Canon 60D review. The good news is that they compared the noise perofrmance with “our” new Panasonic GH2: http://www.dpreview.com/reviews/canoneos60d/page11.asp. It’s doing pretty well! Maybe we should not pay to much attention at what DxOmark says 🙂
For out japanese readers: Ascii.jp posted a GH2 review!

Why no attention to DXOmark?
The result from dpreview matches with dxo. GH2 is 1/3 – 2/3 stops worse than Canon 60D. If you look carefully to the raw tests you’ll see that.
A good many valubales you\’ve given me.
I just checked out D7000 sensor vs. Panasonic GH2 and Olympus E-P2 one on DxO website. And dynamic range of that new Sony sensor is huge. The question is that DxO measuring are visible on real life photos (RAW processed)? Is the DxO reliable or it’s better to forget about it and just take photos? New MFT/FT sensor with 14 EV would be great.
The big adversary worth to take in account is not Canon but cameras equipped with Sony sensor (Sony, Kodak, Nikon).
Even with this remark I also think GH2 is a pretty good image quality camera.
DxOmark tests only sensor which is only one third of what makes the final image. The optics and the photographer are the other two thirds, as usually disregarded. (The usual reference: http://www.amazon.com/Best-Camera-One-Thats-You/dp/0321684788/ )
I think for the photography as an art, this are the most exciting, yet at the same time, the direst times. Exciting because capacities to experiment were greatly expanded in the last years. Dire because people pay more attention to the progress of the technology than to the outcome, the images.
After two years with E-520, I pretty much never exhausted capabilities of the camera. It took me some time to realize that my photos are lacking not because of the poor sensor (and poor it is), but because I simply fail as an artist. (I really felt that I hit the wall – and it is not the camera’s fault. Many great moments were wasted.) I guess same goes for many others, and that is why in the end, as humans, we pay more attention to what we can grasp not what we cannot: the tech, not the art.
I know it has been said gazilion times but
We need fixed aperture/shutter speed + variable ISO to determine the true noise levels,
Each camera’s ISO value is different (for example:GH2 ISO 400 is like ISO 300 on GH1)
EOS 60D and GH2 has very similar measured ISO values though.
True about different real ISO makes those tests irrelevant 🙁
*just a little ,not completely.
Perhaps you didn’t fail as an artist so much as you haven’t found the artist within you yet.
DxOmark is very solid and there is no reason their results should not be trusted.
That said, what DxOmark do is like testing just a car’s engine: no matter how powerful it is the ‘real’ results delivered by it will always depend on many other factors like tires, brakes, suspension, driver’s experience, track, traffic, weather and so on.
DxOmark just tell a part of the history, and that’s why most of the time huge differences in sensor performance may not be so big in the real life. Whoever buys a camera based in DXOmark results alone, is fooling himself.
people who pay attention to dxo scores are:
1- people who make their own body using a camera sensor with their own coded software so probably noone….
2- people who didn’t and probably never shoot nice photos, but instead browsing forums all day. (gearhead, trolls)
According to dxo scores, besides ISO sony a55 sensor is better then nikon d3s
what does that means? you can get higher IQ with a55. NO
very ture
Why to pay attention?
=> Because you know, what you can do with the camera!
(what is senzor capable .. but DxO results will not tell you how to use it)
There are differences between manufacturers: mainly different exposition and different approach to DR handling (not only noise reduction during JPEG creation), which have bigger impact how most people is able to imagine.
Evaluation of RAW data is not influenced via this processing => you can get imagination what is possible with the right RAW converter
>People who pay attention to dxo scores are:
3) People who shoot in RAW!
You completely forgot about that did you?
I don’t know about you, but I use a camera, not a sensor. DxO is only part of the picture, as it were.
> According to dxo scores, besides ISO sony a55 sensor is better then nikon d3s

Why not?
D3s is optimize for high ISO. Why A55 can not be better in low ISO?
check these crops from http://www.imaging-resource.com reviews on ISO 1600:
1000D: http://www.imaging-resource.com/PRODS/T1I/ZXSIhSLI1600-LEAF.JPG
7D: http://www.imaging-resource.com/PRODS/E7D/ZE7DhSLI01600_NR_2D-LEA.JPG
You think this can not be true? Check DxOmark color graphs…
For those of us interested in DxOMark, there is a site extracting more information out of those data.
Please have a look at http://www.sensorgen.info to explore various cameras measures of quantum efficiency, the read noise and the saturation capacity.
Looking at these data, certainly the Olymous and to a lesser extent Panasonic would benefint from a further evolution in sensor technologies.
I think the DPReview raw results seem to agree with DxOMark on high-ISO performance: the GH2 is around 1 stop better than the G2 and significantly below the Nikon D7000. Pity that the GH1 isn’t incorporated in the DPReview widget, but I suspect that the GH2 and GH1 will be very much alike. I never look at jpeg results because I shoot in raw and I don’t like what noise reduction does to a picture.
I have pre-ordered the GH2 but I’m reconsidering if I want to spend that amount of money for a mere 1 stop improvement over my G1. I know that the GH2 offers (probably superb) video, faster AF and a somewhat better viewfinder, but still it’s a lot of money.

I also don’t see this in the Dpreview (RAW) results.

NEX-5 is really ahead GH2 too.
