Panasonic S1 vs Panasonic GM1

Below, we are contrasting the Panasonic S1 versus Panasonic GM1, one being a Pro Mirrorless and the other is a Entry-Level Mirrorless and both are offered by Panasonic. There is a crucial difference between the sensor resolutions of the S1 (24MP) and GM1 (16MP) and the S1 (Full frame) and GM1 (Four Thirds) feature totally different sensor dimensions.

The S1 was brought out 5 years later than the GM1 and that is quite a serious gap as far as tech is concerned. Both of the cameras come with different body type with the Panasonic S1 being a SLR-style mirrorless camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before diving in to a detailed comparison, below is a brief view of how the S1 grades versus the GM1 in terms of portability, imaging, features and an overall rating.

Often, it is hard to envision the gap between sensor sizing purely by going over a spec sheet. The photograph here should provide you a more clear sense of the sensor dimensions in the S1 and GM1.

Clearly, each of these cameras posses different megapixels and different sensor sizing. The S1 due to its larger sensor will make achieving shallower depth of field easier and the Panasonic S1 will deliver more detail having its extra 8MP. Greater resolution will also make it easier to crop pics somewhat more aggressively. The newer S1 is going to have a benefit when it comes to sensor tech.
