Panasonic GM1 vs Pentax K-1 Sensor Comparison

Generally, its difficult to imagine the contrast between sensor sizes merely by reviewing technical specs. The pic here might offer you a much better sense of the sensor sizing in the GM1 and K-1.

As you can tell, both of these cameras come with different megapixel count and different sensor sizes. The GM1 because of its tinier sensor is going to make achieving shallow depth of field tougher and the Pentax K-1 will offer more detail having its extra 20MP. Higher resolution will make it easier to crop pictures a good deal more aggressively. The more aged GM1 is going to be behind in sensor tech.
