Normally, it can be hard to visualize the gap in sensor sizing just by researching specifications. The visual below should provide you a much better sense of the sensor sizes in the WG-2 GPS and A7c.

Plainly, each of the cameras feature different megapixels and different sensor sizing. The WG-2 GPS having a smaller sensor is going to make getting shallower depth of field more challenging and the Sony A7c will render greater detail with its extra 8 Megapixels. Greater resolution can also help you crop pics way more aggressively. The older WG-2 GPS will be disadvantaged in sensor innovation.
