Olympus E-M1 vs Olympus SP-620 UZ

Let's look a little more closely at the Olympus E-M1 and Olympus SP-620 UZ, one being a Pro Mirrorless and the other is a Small Sensor Superzoom and they are both created by Olympus. The image resolution of the E-M1 (16MP) and the SP-620 UZ (16MP) is fairly similar but the E-M1 (Four Thirds) and SP-620 UZ (1/2.3") boast different sensor dimensions.
