As part of our image quality testing for the Fujifilm FinePix F770 EXR, we've shot our resolution chart. If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the Fujifilm FinePix F770 EXR is capable of resolving up to around 18 (line widths per picture height x100) in its highest quality JPEG files. For a full explanation of what our resolution charts mean, and how to read them, check out our full explanation of our camera testing resolution charts. Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100: ISO 100, score: 18 (Click here to see the full resolution image) ISO 200, score: 16 (Click here to see the full resolution image) ISO 400, score: 12 (Click here to see the full resolution image) ISO 800, score: 12 (Click here to see the full resolution image) ISO 1600, score: 12 (Click here to see the full resolution image)

We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

Here we compare the Fuji FinePix F770 EXR with the Fuji FinePix F600 EXR, Canon PowerShot SX260 HS and Panasonic Lumix TZ-30.

Signal to noise ratio

These results show that the JPEG files from the Fuji FinePix F770 EXR have a lower signal to noise ratio than those from the Fuji FinePix F600 EXR,Canon PowerShot SX260 HS and Panasonic Lumix TZ-30 at almost every sensitivity, with results closest in quality to the Fuji F600 EXR.

Dynamic range

Again, the Fuji FinePix F770 EXR shows less dynamic range in its JPEG images than the Fuji FinePix F600 EXR, Canon PowerShot SX260 HSand Panasonic Lumix TZ-30. The difference is most pronounced with the Canon and Panasonic, while the Fuji F600 EXR's images are the most similar, although still better.
