Noise, resolution and sensitivity

These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured using matching 105mm macro lenses. We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution is at the specified sensitivity setting.

As you would imagine, by packing 12.3 million photosites onto a Four Thirds-size sensor, the Panasonic Lumix DMC-G2 is capable of resolving as much, if not more detail than it’s APS-C-format counterparts.

At a sensitivity of ISO 100 and 200, JPEG images are capable of resolving detail just past 24 on our resolution chart.

Raw files shot at ISO 3200 on the G2 are capable of resolving just beyond 18 on our test chart, albeit with a slight degradation in quality due to the default level of noise reduction. At the maximum ISO 6400 setting, the camera only really reaches 16, but it still gives the impression of detail at 24.

Noise is well controlled and is only really obvious at ISO 6400. In well-exposed areas, it isn’t a problem and is well disguised with a slight smudging of detail. Underexposed areas do suffer from cyan and magenta patches of noise, as well as an impressionistic smudging effect caused by noise reduction.

UNDERSTANDING THE GRAPH: This graph shows the brightness values recorded by the test camera when it is used to photograph a stepped graduation wedge. The wedge has transmission values in 1⁄2EV steps ranging from 0 to 12EV. The camera’s exposure is set so the 12EV section in the wedge has a brightness value of 255. Software analysis of the image then determines the recorded brightness values of all the other steps and calculates the camera’s dynamic range.
