Sigma Quattro vs Sony A7R Sensor Comparison

Typically, it can be difficult to picture the contrast between sensor sizes only by checking a spec sheet. The picture below may provide you a greater sense of the sensor sizes in the Quattro and A7R.

As you can see, both of these cameras have different megapixels and different sensor sizes. The Quattro using its tinier sensor is going to make achieving bokeh more difficult and the Sony A7R will give more detail using its extra 7 Megapixels. Higher resolution can also make it easier to crop pictures a bit more aggressively. The more modern Quattro should have a benefit with regard to sensor tech.
