BTW - are you sure that the focus not is on the wall for the pictures?

As sure as I can be I selected the af point my self, and my tripod is professional line from manfrotto. Its possible the camera is playing tricks with AF

This is an annoying thing with Bayer CFA cameras. In order to improve sharpness, the software uses tricks, like edge detection. But, soft flowers do not really have any nice edges.

This means that the wall, that has edges in the patterns, can actually be sharper, even if it is more out of focus.

I would really like a non Bayer CFA camera for that reason. Therefore I have been interested in the Sigma/Foveon cameras. And they can deliver a uniform sharpness. They have other problems though.
