Those targets support well my idea that the problem with the *ist D can be the low-pass filter in front of the sensor, causing both lower moire (color artifacts) and lower resolution. When you shoot natural subjects (not optical targets), the moire is seldom a problem, while lower resolution is always visible. I believe you answered the question about the *ist D performance.
