As part of our Panasonic G3 review we shot our resolution chart at every sensitivity setting with the Panasonic Lumix G Vario 14-42mm f/3.5-5.6 ASPH MEGA OIS kit lens mounted.

These resolution chart images have been updated following the firmware update that changed the G3's output from 15.70 Mp (4576x3432 pixels) to 15.83Mp (4592x3448 pixels).

The update appears to have improved the G3's image quality very slightly.

If you download the images and view the central section at 100% (or Actual Pixels) you will see that, at ISO 100 the Panasonic G3 is capable of resolving up to 24 (line widths per picture height x100) in it's highest quality JPEG files. Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
