Leica X1 review: Resolution and image quality
As part of our image quality testing of the Leica X1, 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 X100 is capable of resolving up to around 18 (line widths per picture height x100) in its highest quality JPEG files and 22 (LWPPH x100) in its raw files.
Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
JPEGS
ISO 100, score: 18
ISO 200, score: 18
ISO 400, score: 18
ISO 800, score: 18
ISO 1600, score: 16
ISO 3200, score: 16
Raw
ISO 100, score: 22
ISO 200, score: 22
ISO 400, score: 22
