At ISO 800 noise reduction starts having a bigger impact on the overall image quality than the lens. Therefore the difference between the two cameras' output appears to be decreasing. Having said that the Panasonic results are still visibly softer than the Canon's. The lens is soft to start with but at this sensitivity the noise reduction smearing is taking its toll as well. Nonetheless, the image is far from being noise-free. Both luminance and chroma noise are becoming quite intrusive.

There is a lot of noise in the Canon image too but at least there's some detail left and the overall result still looks relatively sharp. The SD850's ISO 800 output is perfectly usable as long as you don't expect miracles and are only looking to produce small prints.
