Often, it is very tough to visualize the difference in sensor sizing just by going through a spec sheet. The graphic underneath should give you a much better sense of the sensor measurements in the E-PL5 and K-1.

As you can see, both of these cameras offer different megapixels and different sensor sizing. The E-PL5 featuring a smaller sensor is going to make shooting shallow depth of field tougher and the Pentax K-1 will produce more detail as a result of its extra 20 Megapixels. Greater resolution can also let you crop photos a little more aggressively. The older E-PL5 will be behind with regard to sensor innovation.
