This shot shows that at f22, the minimum aperture possible, diffraction is not ruining a 17mm view on the A900 with its relatively large pixel pitch. The point of focus is easily found, in the first third of the boat where there is some rope above very sharply detailed textured boat floor. f22 is not enough to keep the prow sharp, or the background view. Remember, when viewing this on a 96dpi monitor, you are viewing a 'print' over five feet high close up!
