Sometimes, its hard to envision the difference between sensor measurements simply by going over specs. The photograph here will offer you a much better sense of the sensor sizing in the E-P1 and E70.

All in all, each of these cameras posses different resolutions and different sensor measurements. The E-P1 featuring a larger sensor will make shooting shallow depth of field easier and the Olympus E-P1 will offer extra detail as a result of its extra 2 Megapixels. Greater resolution will help you crop images somewhat more aggressively. The younger E-P1 is going to have an edge when it comes to sensor innovation.
