This histogram shows an almost perfect distribution of tones covering about a 4 stop dynamic range — from deep shadows on the left to just short of bright highlights on the right.
This fits comfortably within the approximately 5 stop dynamic range capability of most digital imaging chips.

it's just i have to admit the DR of GF3 (quite close to GH2's) is way behind Sony NEX's, and sometimes it's possible to push to the limits.
The K5 uses the same sensor as the NEX-5N.
Great write up and comparison. Extremely informative and easy for a noob like me to understand.
When I compare photos of the K5 and GH2, I also see a subtle difference that goes beyond the objective qualities of sharpness and dynamic range (if those can be objective). While the GH2's images appear to be sharper for the most part, the GH2 also appears more "clinical" to my eyes. The K5 has more ... depth? More of a 3D? This is probably just a matter of opinion though. Not sure if it's quantifiable.
Of course, if I had to pick between the two, I'd pick the ...
I rarely find myself on that edge, so my K5 is probably going to find itself in the classifieds pretty soon.
It will be interesting to see how long it takes Panasonic to catch up to this latest generation of Sony sensor technology. As you are no doubt aware, the difference between APS-C and 4/3 sensor size isn't all that much, and the predicted DR disparity based on sensor size would be less than half a stop.
Wow, thanks, I didn't know that, apparently K5 should be real good.
I own a GF3, knowing GH2/G3 are supposed to have superior sensors with higher resolution, am I right to think that the 16MP sensor may bring more noise or some downsides than the 12MP? However GX1's 16MP ISO-1600 seems quite clean!
