Panasonic GH5S vs Pentax S1

Below is a complete comparison of the Panasonic GH5S and Pentax S1, former being a Pro Mirrorless while the latter is a Small Sensor Compact by manufacturers Panasonic and Pentax. There exists a considerable gap between the sensor resolutions of the GH5S (10MP) and S1 (14MP) and the GH5S (Four Thirds) and S1 (1/2.3") provide different sensor sizes.

Photography Glossary

The GH5S was released 6 years later than the S1 and that is quite a large difference as far as technology is concerned. Each of the cameras have different body design with the Panasonic GH5S being a SLR-style mirrorless camera and the Pentax S1 being a Compact camera.

Before we go right into a in depth comparison, here is a brief overview of how the GH5S matches up against the S1 when considering portability, imaging, features and an overall grade.

Take into consideration, the weight of an ILC will vary based on the lens you have at that moment. Below is a front view sizing comparison of the GH5S compared to the S1.

Taking into account dimensions and weight, the portability rating of the GH5S and S1 is 62 and 93 respectively.

Sometimes, it is difficult to imagine the difference between sensor measurements only by looking at a spec sheet. The graphic below should offer you a more clear sense of the sensor sizing in the GH5S and S1.

As you can see, each of the cameras provide different resolutions and different sensor measurements. The GH5S because of its bigger sensor is going to make shooting shallow DOF simpler and the Pentax S1 will resolve greater detail as a result of its extra 4MP. Higher resolution will also make it easier to crop photographs more aggressively. The more modern GH5S should have an advantage with regard to sensor tech.
