On this page, we will be analyzing the Sony A7S II and Sony W310, one is a Pro Mirrorless and the latter is a Ultracompact and they are both designed by Sony. The image resolution of the A7S II (12MP) and the W310 (12MP) is relatively comparable but the A7S II (Full frame) and W310 (1/2.3") provide totally different sensor measurements.

The A7S II was revealed 5 years after the W310 which is a fairly serious gap as far as camera technology is concerned. Both of these cameras have different body design with the Sony A7S II being a SLR-style mirrorless camera and the Sony W310 being a Ultracompact camera.

Before going straight to a detailed comparison, here is a brief summary of how the A7S II scores versus the W310 in terms of portability, imaging, features and an overall mark.

Here is a preview of the gallery photos for Sony Alpha A7S II and Sony Cyber-shot DSC-W310. The full galleries are viewable at Sony A7S II Gallery and Sony W310 Gallery.

If you are looking to travel with your camera, you are going to need to think about its weight and size.

Do not forget, the weight of an Interchangeable Lens Camera will change based on the lens you have attached during that time. The following is a front view physical size comparison of the A7S II compared to the W310.

Taking into account dimensions and weight, the portability grade of the A7S II and W310 is 68 and 96 respectively.

Normally, its tough to visualise the difference in sensor dimensions purely by going through a spec sheet. The picture underneath will help give you a better sense of the sensor dimensions in the A7S II and W310.

Clearly, the two cameras have the same megapixel count albeit not the same sensor dimensions. The A7S II has the bigger sensor which is going to make getting shallower depth of field less difficult. The more recent A7S II will have an edge in sensor tech.
