Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.
We chose three rival cameras to the Panasonic G7 to see how it measured up in our lab tests: the Fuji X-T10, Olympus OM-D E-M10 and Sony A6000.
We carried out lab tests on the G7 across its full ISO range for resolution, noise (including signal to noise ratio) and dynamic range. We test the JPEGs shot by the camera, but we also check the performance with raw files. Most enthusiasts and pros prefer to shoot raw, and the results can often be quite different.
Panasonic G7 resolution charts
We test camera resolution using an industry-standard ISO test chart that allows precise visual comparisons. This gives us numerical values for resolution in line widths/picture height, and you can see how the G7 compares with its rivals in the charts below.
JPEG resolution analysis: The G7's 16Mp Four Thirds-type sensor gives a very good account of itself throughout the sensitivity range, even coming close to the 24Mp Sony A6000 for detail resolution.
Raw (converted to TIFF) resolution analysis: When raw files are converted using the supplied Silkypix software with no noise reduction applied, the level of detail falls a little behind that of the JPEG files; a bespoke conversion can draw out more detail.
