We are not talking about advertizement, we are talking about rumors about specifications - and the GH2 sensor is indeed specified as 18 mpix.

Sure, in the spec sheets it says 18 MP total pixel count, but it also says 16 MP effective pixel count, and that's the number that was quoted in the advertising. In the original press release, for example, you can read about "the newly developed 16.05-megapixel multi-aspect Live MOS Sensor". And that's how people usually talk about the pixel count of sensors. The GH3 or E-PL5, for example, have never been referred to as 17 MP cameras, neither in advertising, reviews or on rumor sites. They're 16 MP cameras, because that's the size of the images they output.

In other words, the GX2 sensor most likely have an effective pixel count of 18 MP. Of course, if you use the entire GH2 sensor, you do get 18 MP, but the image circle doesn't cover the whole sensor, which is slightly larger than a standard 4/3 sensor. The corners of the sensor aren't covered. This suggests a new 18 MP sensor is being used in the GX2.

for a long ,i want to know ,how many size of area image circle ?,please scale to mm/cm

of radius or circle (2*Pi*r)  ,thank very much.

Ahem, if you read down a bit "Of course being rumours they may be making up the highest resolution claim themselves but at this point we can't know one way or the other."


6) Low quality EVF, maybe 200kpix unit from LF1, or sequential junk from G-series - high probability (have to fit it over screen somehow).

What's wrong with those EVFs? The quality is great even at 640x480, an 800x600 or 1024x768 version would be outstanding. (Unless you also think all sequential DLP projectors are junk too).

What is wrong? Low real resolution (400kpix or so) and crazy sh!t colors when panning. We are comparing with E-M5 and VF-4, which are simply so much better.

Actually it's a full colour resolution 800x600 EVF, which is technically the same as a full resolution colour 1.44M dot EVF (800x600x3). I think many 1.44M dot EVFs use sub pixel rendering which brings their perceptual resolution up somewhat, but not by a huge amount.

As for colour tearing it's no worse than popular DLP projectors.

Everyone might want it and Panasonic won't make enough of them to satisfy demand. Stores will jack up the price massively and then everyone who doesn't have one will say the OMD has better IQ because of its retro design.

I think the OP should relax. All these fears about what might go wrong are not good for a person. The camera will come. It will have good things, and things that we might find disappointing. It is not worth worrying, or the nit picking of rumours, or being swept away by negative emotions. Go outside and take a few photos. Enjoy the day!

Again, we are NOT talking about advertising or press releases. What is so hard to understand?

As I said, it's not just in advertising, but also in reviews and on rumor sites. I have never seen a rumor about an upcoming camera, that states the total pixel count of the sensor. They always state the effective pixel count, since that's what matters. Again, noone has ever referred to the GH3, E-M5 or E-PL5 as 17 MP cameras, not on rumor sites or anywhere else that I have seen; they have always been referred to as 16 MP cameras. Why then should the pixel count of the GX2 be interpreted as the total, and not the effective pixel count?
