As you can see, the two cameras posses the exact same sensor measurements albeit different MP. You should count on the Pentax RZ18 to give you more detail having its extra 4MP. Higher resolution can also make it easier to crop photographs somewhat more aggressively. The older E85 is going to be behind in sensor tech.
