Olympus E-PM1 vs Panasonic GX9 Sensor Comparison

More often than not, it is very difficult to visualise the contrast between sensor measurements merely by reading through a spec sheet. The graphic below will help offer you a more clear sense of the sensor sizing in the E-PM1 and GX9.

As you can see, each of the cameras feature the identical sensor size but not the same MP. You should anticipate the Panasonic GX9 to resolve greater detail due to its extra 8 Megapixels. Greater resolution will help you crop photos way more aggressively. The older E-PM1 is going to be behind in sensor technology.
