In comparing images shot with both the G1 and G2 (shot at roughly the same time) I am struck with the difference in character. The color differences have been covered in the G2 reviews but not enough has been said relating to the sharpness/acutance differences. (Acutance is commonly described as how distinct an edge there is between adjacent light and dark areas.)
The G2 is “sharper”. There is much more detail than the mere addition of a few pixels can explain. Yet oddly, the G1 photos seem sharper when viewed from a distance. There seems to be a certain amount of “edge sharpening” going on in the G1 even if “sharpening” is set = Low.
The G2 images are more like the D-30 images that I have seen. They can look softer if you don’t examine the detail. (Of course it’s easy enough to add that “acutance” to the G2 and D30 shots and replicate the “bright and snappy” sharpness that the G1 shots have…)
Is anyone else noticing this?
There are several good general comments on sharpness v acutance at:

Six months ago I ran a search on “sharpening” to learn what values to use in the “unsharp mask” feature in photoshop. I now know at least 12 ways to adjust sharpness in photoshop, with I don’t want to calculate how many variations. Isn’t this a wonderful hobby?
