As you can see, both cameras come with the identical sensor size but not the same resolution. You can anticipate the Panasonic GX850 to provide you with extra detail due to its extra 4MP. Greater resolution can also help you crop images a good deal more aggressively. The more aged E-P1 will be behind in sensor technology.
