Olympus E-PM1 vs Panasonic G100 Sensor Comparison

More often than not, it is very tough to visualise the difference between sensor measurements simply by checking technical specs. The visual here will offer you a more clear sense of the sensor sizes in the E-PM1 and G100.

As you have seen, both of the cameras feature the identical sensor size but not the same MP. You should anticipate the Panasonic G100 to give you greater detail using its extra 8 Megapixels. Greater resolution will let you crop pics way more aggressively. The older E-PM1 is going to be disadvantaged when it comes to sensor technology.
