Oftentimes, its tough to visualize the contrast between sensor dimensions only by going over a spec sheet. The picture here should offer you a much better sense of the sensor sizes in the a1 and H20.
Clearly, the 2 cameras posses different resolutions and different sensor dimensions. The a1 with its larger sensor is going to make achieving bokeh less difficult and the Sony a1 will offer you extra detail because of its extra 40 Megapixels. Greater resolution will let you crop images somewhat more aggressively. The newer a1 provides a benefit in sensor innovation.
