Panasonic S1R vs Panasonic GM5

Below, we are analyzing the Panasonic S1R and Panasonic GM5, one is a Pro Mirrorless and the other is a Entry-Level Mirrorless and both are built by Panasonic. There exists a significant gap among the sensor resolutions of the S1R (47MP) and GM5 (16MP) and the S1R (Full frame) and GM5 (Four Thirds) use totally different sensor dimensions.

The S1R was released 4 years after the GM5 which is a fairly sizable gap as far as camera technology is concerned. Both cameras come with different body type with the Panasonic S1R being a SLR-style mirrorless camera and the Panasonic GM5 being a Rangefinder-style mirrorless camera.

Before delving in to a detailed comparison, below is a short summation of how the S1R scores vs the GM5 in the way of portability, imaging, features and an overall mark.

Below is a sample of the gallery pictures for Panasonic Lumix DC-S1R and Panasonic Lumix DMC-GM5. The complete galleries are available at Panasonic S1R Gallery and Panasonic GM5 Gallery.

For those who are looking to travel with your camera frequently, you will need to think about its weight and size.

Do not forget, the weight of an Interchangeable Lens Camera will vary based on the lens you have attached at that moment. Below is the front view sizing comparison of the S1R against the GM5.

Using dimensions and weight, the portability rating of the S1R and GM5 is 54 and 91 respectively.

Sometimes, it's difficult to visualise the difference in sensor dimensions purely by seeing technical specs. The image below will help provide you a greater sense of the sensor measurements in the S1R and GM5.

As you have seen, both of those cameras posses different resolutions and different sensor dimensions. The S1R because of its larger sensor will make achieving shallow depth of field less difficult and the Panasonic S1R will produce extra detail as a result of its extra 31 Megapixels. Greater resolution will help you crop photos somewhat more aggressively. The more recent S1R will have an edge in sensor tech.
