For measuring image resolution, the ISO-12233 compliant I3A/ISO Camera Resolution Chart was used. Purpose of this test is to acquire an objective and qualitative appraisal on sensor performance in the areas of resolution and lens quality.

ISO Resolution Chart for Electronic Still Cameras

The numbers labeled on the chart signify a 1/100-line per picture height. A value of 10 represents 1000 lines per picture height (LPH). From a series of images taken of the chart using the kit lens at different aperture settings, the sharpest image would be selected to determine the resolution quality of the Canon 400D. From the sample shot chosen, fine lines were still visible pass 1750 H on both horizontal and vertical LPH, reflecting the impressive resolution quality of the Canon 400D.
