At ISO 400 the difference is much more obvious (well, it is at 100% on-screen, not sure it'd be so obvious in a postcard print), and it's all down to Sony and Canon's very different approach to noise reduction. Where Canon's lighter touch retains more detail but looks visibly grainy, Sony's 'take no prisoners' approach to noise produces a smoother, but less crisp result that has lost an awful lot of fine, low contrast detail (see the noise section of the review for more on this). It'd be fine for a small print but you wouldn't want to use this for anything with lots of detail or for larger prints.
