Resolution Chart Comparison

Shots here are of our new 'version two' resolution chart which provides for measurement of resolution up to 4000 LPH (Lines Per Picture Height). A value of 20 equates to 2000 lines per picture height. For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected. Studio light, cameras set to aperture priority (optimum aperture selected), image parameters default. Exposure compensation set to deliver approximately 80% luminance of white area.

Measurable results

The Pentax K200D's JPEG resolution is not quite but almost on the same level as the other 10 Mp cameras in this comparison, it trails quite a bit behind the 12.2 MP Canon though. The Pentax image also shows the largest amount of color moire. Most of this can be attributed the the K200D's JPEG engine. As we've demonstrated in previous sections of this review the K200D's output improves significantly when you shoot in RAW.
