What can the ISO 12233 test diagram do?

The ISO 12233 Test Chart is the I3A/ISO standard for measuring the resolution of electronic still imaging cameras. The chart I am using is a very expensive, finely printed variation of the ISO 12233 standard that extends resolution to 4,000 lines per picture height (l/ph) and features other benefits as well. This iso test chart serves as a good visual indicator of sharpness as well as CA (Chromatic Aberration) and distortion.

3nh provides one-stop service on enhanced ISO 12233 standard 4000 lines resolution test chart (0.5x, 1x, 2x, 4x, 8x), and iso standard 2000 lines resolution test chart (0.5x, 1x, 2x, 4x, 8x), including the reflective and transparency charts, test light source and test software.
