Again, there is not an awful lot of difference between the two cameras' output, you'll only see any when 'pixel-peeping'. The Canon retains a relatively large amount of detail at higher sensitivities by only mildly blurring luminance noise (grain) while the Panasonic targets luminance noise in a more determined manner. This results in smoother and less noisy but also softer and less detailed images.
