Rob, your Mount Stuart photo doesn't display aperture. If it's something on the sensor, that should be more obvious at high f-numbers. But also, contrast and other adjustments in pp would bring it up. Your other two shots are f/8, where such spots would not normally be visible.

Have you tried shooting a uniformly illuminated subject, eg sky, fully stopped down?
