The A7S was introduced 18 months prior to the RX1R II making the cameras a generation away from one another. Each of the cameras offer different body type with the Sony A7S being a SLR-style mirrorless camera and the Sony RX1R II being a Large Sensor Compact camera.

Before diving through a more detailed comparison, below is a brief view of how the A7S scores versus the RX1R II with regards to portability, imaging, features and an overall mark.

This is a sample of the gallery pics for Sony Alpha A7S and Sony Cyber-shot DSC-RX1R II. The whole galleries are available at Sony A7S Gallery and Sony RX1R II Gallery.

For anybody who is aiming to travel with your camera often, you're going to have to take into account its weight and measurements.

Bear in mind, the weight of an Interchangeable Lens Camera will differ dependant on the lens you choose during that time. Underneath is the front view dimension comparison of the A7S compared to the RX1R II.

Sometimes, it is tough to see the difference between sensor dimensions only by reading a spec sheet. The image here may offer you a more clear sense of the sensor sizing in the A7S and RX1R II.

Clearly, both of these cameras offer the same exact sensor sizing but not the same resolution. You should expect to see the Sony RX1R II to offer extra detail using its extra 30 Megapixels. Greater resolution will also make it easier to crop pics a little more aggressively. The more aged A7S is going to be disadvantaged in sensor innovation.
