Plainly, each of the cameras have different megapixels and different sensor measurements. The 7040 having a tinier sensor will make getting shallow depth of field more challenging and the Olympus 7040 will offer greater detail having an extra 8MP. Greater resolution will also make it easier to crop images a bit more aggressively. The younger 7040 will have a benefit when it comes to sensor technology.
