The WG-3 was released 3 years prior to the A7S II which is a fairly significant gap as far as camera tech is concerned. Both of the cameras have different body design with the Pentax WG-3 being a Compact camera and the Sony A7S II being a SLR-style mirrorless camera.

Before going into a full comparison, here is a quick highlight of how the WG-3 scores against the A7S II in the way of portability, imaging, features and an overall score.

Below is a sample of the gallery pictures for Pentax WG-3 and Sony Alpha A7S II. The complete galleries are available at Pentax WG-3 Gallery and Sony A7S II Gallery.

In many cases, it's hard to imagine the gap in sensor sizes merely by looking through a spec sheet. The image underneath may give you a much better sense of the sensor measurements in the WG-3 and A7S II.

Clearly, each of the cameras provide different megapixel count and different sensor sizes. The WG-3 featuring a smaller sensor is going to make achieving bokeh tougher and the Pentax WG-3 will provide you with more detail as a result of its extra 4MP. Greater resolution will let you crop pics more aggressively. The more aged WG-3 will be disadvantaged with regard to sensor innovation.
