Minolta's successor to the 7hi, the A1 here (http://www.dpreview.com/articles/minoltadimagea1/).
What's interesting about this is the image stablization is built in the camera. The CCD actually moves up/down and side to side. I know I'm not as smart as the engineers, but how do they keep it from vignetting? Or having the CCD not in the center of the optical path. I would think image quality might deteriorate.

The lens has excess coverage, much like a 35mm lens on the Canon 10D or Nikon D100. The image circle is about 40mm in diameter and the long dimension of the chip is about 22mm. As long as the chip remains within the circle, no vignetting.
