Hello Tournesol and All,
As an F-828 user, I too am looking for a portable everyday camera.
The shootout images are very interesting.
I made some crops of the last image.
Regarding resolution, I concentrated on some rooftop antenae on the right and left of the images; and also on the little white house, with its windows about the center of the image.
To facilitate posting and viewing them I posted them on my Smugmug gallery. If this is improper I will remove them at the request of Dcresource.com
I won't state my observations to avoid leading you one way or the other.
However, regarding resolution, there appears to be a big difference between the two cameras:

I hope all this adds to the discussion, Regards, Nicholas
