Generally, it can be hard to picture the contrast between sensor sizes simply by reading specifications. The image here should offer you a clearer sense of the sensor dimensions in the SL and E-M1 III.

To sum up, the two cameras come with different megapixels and different sensor sizes. The SL featuring a larger sensor is going to make achieving shallow depth of field easier and the Leica SL will deliver greater detail utilizing its extra 4 Megapixels. Greater resolution can also allow you to crop images a good deal more aggressively. The more aged SL is going to be behind when it comes to sensor innovation.
