Sony Alpha A77 review

24Mp and a groundbreaking viewfinder, bring it on!

As part of our image quality testing fo the Sony Alpha 77, we've shot our resolution chart with a Sigma 50mm f/1.4 EX DG HSM 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 100 the Sony Alpha 77 is capable of resolving up to around 28 (line widths per picture height x100) in its highest quality JPEG files. Although the resolution lines are clearly distinguishable there is, however, some disruption from about 24 LW/PH x100 onwards.

For a full explanation of what our resolution charts mean, and how to read them please take a look at the resolution charts article.

Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
