Bloom confirmed that the GH2 is either 2 or 9, if you cross-reference his Twitter with his Facebook.
Edit: Need to stop typing quickly wrote "Boom" instead of "Bloom", which must have been a Freudian slip in reference to the spike in attention his posts garner for a given product. :)
@disneytoy both nikon and 5n has aps-c sized sensors. We know the second image is not Nikon. But if you look closely the bokeh is slightly bigger than on 3 and 9.
If 3 is the AF100 that's pretty nuts. Look at the pixelization happening to the right of her head where the light falls off, and the stairstepping in the bokeh on the left side.
9 is the smallest sensor and 1 is the largest. Just look at the Bokeh and you can tell the difference in crop factor.The larger the sensor the more compression. You have to widen from a Full-frame crop to a 2x crop to get the same frame. Wider lens = smaller bokeh.
