i don't remember which link talked about the sensor size. i have read so many. i was lead to believe that the sensor was to be closer to the aps size found in the dslr.
i certainly didn't mean to imply that the new pen is any different than other 4:3 systems, but that it is suppose to be a larger sensor than the consumer point and shoot camera.
For myself. i have been wanting to replace an older coolpix camera. I have been looking at the g10, and i did take a look at the gh-1 which is larger than my needs as i already have several other cameras .
the sigma dp is suppose to have one of the largest sensor in the point and shoot range, which attraches me, but other than that i have seen much else to encourage me to purchase.
