All in all, both of the cameras have different megapixels and different sensor dimensions. The SP-800 UZ having a tinier sensor is going to make shooting bokeh more difficult and the Pentax 645D will resolve extra detail using its extra 26MP. Higher resolution can also make it easier to crop pictures a bit more aggressively.
