The A7S was revealed 7 years prior to the a1 which is a fairly serious gap as far as camera technology is concerned. Both the cameras have the same body design (SLR-style mirrorless).

Before diving right into a full comparison, here is a simple overview of how the A7S scores vs the a1 for portability, imaging, features and an overall mark.

Below is a preview of the gallery photos for Sony Alpha A7S and Sony Alpha a1. The full galleries are provided at Sony A7S Gallery and Sony a1 Gallery.

If you are intending to travel with your camera often, you will have to think about its weight and volume.

Normally, it can be hard to visualize the difference in sensor dimensions just by looking through a spec sheet. The image here should provide you a greater sense of the sensor sizes in the A7S and a1.

Clearly, both of those cameras provide the same sensor dimensions albeit different MP. You should count on the Sony a1 to result in greater detail because of its extra 38 Megapixels. Higher resolution will also help you crop photographs more aggressively. The more aged A7S will be disadvantaged in sensor technology.
