As you can see, the 2 cameras posses different megapixel count and different sensor measurements. The A550 with its larger sensor will make shooting shallower depth of field simpler and the YI M1 will show greater detail having an extra 6 Megapixels. Greater resolution will let you crop photos somewhat more aggressively. The older A550 will be behind when it comes to sensor innovation.
