Nikon D3100 review

Nikon's 14.2MP D3100 is a great choice for novices and those on a budget

As part of our image quality testing we've shot our resolution chart using the Nikon D3100 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 Nikon D3100 is capable of resolving up to around 22 (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 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:
