unprocessed crop of the preceding
full resolution from RAW (DNG) when viewed at original size
AA filters diminish moire at the expense of sharpness
you can see the consequences of this in the wires which have an added color in a moire pattern
I am surprised at how little moire I see with this camera
the folks at Leica/Jenoptik/PhaseOne/Kodak did a fine job
an odd observation is the perfect circle just to the left of the tower near center in this crop
it is only about 5 pixels in size and appears unattached
could this be the famous circle of confusion? ;-)
