The sensor in that image looks a lot smaller to me.

It does??? Look at above comparison Lomskij has made. That for sure looks like 2.5/2.6x crop.
Look at the red and the yellow:
![[Image: Sensor-size-diagram.png]](http://nikonrumors.com/wp-content/uploads/2011/05/Sensor-size-diagram.png)
Matches what Lomskij has posted just about perfectly.
Besides that, there have been a lot of lens patents filed which point to a 2.5x sensor- camera.
Take this patent application for instance:
http://appft.uspto.gov/netacgi/nph-Parse...0090147376
"Preferably, in the optical system (zoom lens system) in accordance with the embodiment, the distance (back focus) on the optical axis from the image-side surface of the lens component arranged closest to the image to the image surface in the shortest state is about 10 to 30 mm. In the optical system (zoom lens system) in accordance with the embodiment, the image height is preferably 5 to 12.5 mm, more preferably 5 to 9.5 mm."
So... lens designed for use with an image height between 5 to 9.5 mm.
"FIG. 13A is an aberration chart upon focusing at infinity in the wide-angle end state (f=30.00 mm). FIG. 13B is an aberration chart upon focusing at infinity in the intermediate focal length state (f=66.44 mm). FIG. 13C is an aberration chart upon focusing at infinity in the telephoto end state (f=107.09 mm)"
So... a zoom lens with a 30-107mm focal length range.
"Preferably, the zoom lens system ZL in accordance with this embodiment is a so-called telephoto zoom lens system including long focal lengths such as about 80 mm at the wide-angle end and about 300 mm at the telephoto end in terms of 35-mm film format. More preferably, the zoom lens system ZL in accordance with this embodiment has a variable power ratio of about 3 to 4. More preferably, in the zoom lens system ZL in accordance with this embodiment, the distance from the image-side surface of the lens component arranged closest to the image to the image surface in the shortest state (the wide-angle end state in each of examples which will be explained later) is about 10 to 30 mm."
They talk about 135 format (35mm) equivalent of about 80-300mm.
300mm would make it a 2.8x crop sensor. The 5 to 9.5mm image height make that crop factor a bit flexible.
The sensor in that image looks a lot smaller to me.
