More MP does not translate into "bigger sensor". The specs do not indicate the sensor size except for the fact that they are M4/3. So, I believe both cameras have the same exact sensor in terms of size but the GH1 cramps up more MP on it.

Wrongggg.

I never believe what pseudo gurus (99, 999 or more) from internet say.

GH1 HAS THE BIGGER CHIP! Even if Panasonic is silent



Sorry - I believe what I see (or min. 98.5% of that)
PS: above these are MY G1/GH1 - perhaps Japanes GH1's have smaller sensor (they are cheaper )

You are both partly right.

At 4/3 the amount of sensor used is the same (18 x 13.5 mm) however when it goes to one of the wider options then to keep within the image circle so making the best use of the lens. Other systems sometimes just chop off the top and bottom losing pixels.

So the sensor is larger but only comes into play when using different aspect ratios and not a single ration uses all the available pixels otherwise it would be outside the image circle and you would get light fall off (vignetting).

I'm still not fully convinced. Looking at the two images, it appears that the sensor on the G1 is mounted slightly further back than on the GH1 (notice the ridges to the side of the sensor on the G1 but not on the GH1). If that's indeed the case, even though the images align pretty good, the size of the G1 sensor will seem smaller simply because it is further from the camera taking the shot than the other sensor. I think it would be advantageous for Panasonic to advertise that the GH1 has a bigger sensor size if that's really the case. It would add another significant difference between the two cameras, which in turn would help justify the price difference. A bigger sensor is always a good selling point.

No. Sensor is marked outside of camera - it is SAME distance :-)

And distance for Micro Four Thirds is ALWAYS 20mm (and must be 20mm)

Awesome shots! How long did you keep the exposure for?
