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.

As part of our image quality testing for the Nikon D800 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 D800 is capable of resolving up to around 36 (line widths per picture height x100) in its highest quality JPEG files. It produces some of the best results we have ever seen from a full-frame SLR.
