Olympus E-400 vs Sony A37 Sensor Comparison

Often, it can be tough to envision the gap between sensor sizing simply by reviewing technical specs. The photograph here will help provide you a clearer sense of the sensor sizing in the E-400 and A37.

As you have seen, the two cameras offer different megapixel count and different sensor sizing. The E-400 using its tinier sensor will make shooting shallow DOF more difficult and the Sony A37 will offer more detail using its extra 6 Megapixels. Greater resolution can also allow you to crop images a little more aggressively. The older E-400 is going to be disadvantaged in sensor innovation.
