Hi,

from that test I cannot distinguish which one has the better
resolution. To my opinion all of them are losing real resolution
at the middle of the graphs. The bottom part is faked on the
most ones. Real resolution would mean:
Seeing 9 lines. 

Regards, Hans.

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.
