As you can see, both cameras have got different megapixels and different sensor measurements. The E-3 with its tinier sensor will make achieving bokeh trickier and the Pentax K-5 will deliver extra detail with its extra 6MP. Higher resolution can also help you crop photographs much more aggressively. The older E-3 is going to be behind when it comes to sensor tech.
