Oftentimes, it can be hard to imagine the contrast in sensor sizes simply by checking out specs. The picture here should provide you a better sense of the sensor sizing in the 1s and A77.

All in all, each of the cameras offer different resolutions and different sensor sizes. The 1s using its smaller sensor is going to make shooting shallow DOF more challenging and the Sony A77 will provide more detail with its extra 12MP. Greater resolution can also help you crop pics a little more aggressively. The more recent 1s should have an advantage in sensor technology.
