Olympus E-M1 vs Panasonic S1 Physical Comparison

		

		

			
For anybody who is looking to carry your camera regularly, you need to think about its weight and size.

Olympus E-M1 vs Panasonic S1 Sensor Comparison

		

		

			
Often, it is very difficult to visualize the contrast between sensor sizing just by checking specifications. The graphic here should give you a far better sense of the sensor sizes in the E-M1 and S1.
Plainly, each of the cameras have different megapixel count and different sensor sizing. The E-M1 using its tinier sensor is going to make shooting shallower depth of field trickier and the Panasonic S1 will resolve more detail having an extra 8 Megapixels. Higher resolution will enable you to crop photographs a bit more aggressively. The older E-M1 is going to be disadvantaged with regard to sensor technology.
