Panasonic Lumix DMC-GX7 review: Closing the gap between APS-C mirrorless rivalsBy Kevin Carter - Tuesday October 15 2013 Sensor Review
With a DxOMark Sensor score of 70 points the image quality of the GX7 is competitive and closes the gap in performance with the best APS-C size sensors used in rival mirrorless models. The sensor has high color depth (at 22.6 bits) and a wide dynamic range of 12.2 Evs. Even the Low-Light ISO score of 718 ISO is not far behind the larger APS-C size sensors used by rival offerings. Each score is similar to the firm’s high-end Lumix DMC-GH3, which is Panasonic’s best performing model, and suggests the sensor in the GX7 is a derivative rather than a completely new design.
