Sony NEX-7 review

Our results from the labs data have been compared against the Panasonic Lumix GH2, Olympus E-P3 and Nikon V1, all top of the range compact system cameras from their respective manufacturers.

The results show that all four cameras produce good results, but the Sony NEX-7's raw (after conversion to TIFF) results for both noise and dynamic range show that it's a cut above the competition.

Resolution

As part of our image quality testing for the Sony NEX-7, we've shot our resolution chart with the Sony 18-55mm f/3.5-5.6 kit lens mounted.

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 200 the Sony NEX-7 is capable of resolving up to around 26 (line widths per picture height x100) in its highest quality JPEG files.
