Panasonic GM1 vs Sigma fp

Let's look a little more closely at the Panasonic GM1 versus Sigma fp, one is a Entry-Level Mirrorless and the other is a Advanced Mirrorless by rivals Panasonic and Sigma. There is a huge difference between the sensor resolutions of the GM1 (16MP) and fp (25MP) and the GM1 (Four Thirds) and fp (Full frame) come with different sensor sizes.

The GM1 was announced 6 years before the fp which is quite a significant gap as far as tech is concerned. Both cameras come with the identical body type (Rangefinder-style mirrorless).

Before diving straight into a comprehensive comparison, below is a brief summation of how the GM1 grades against the fp in relation to portability, imaging, features and an overall score.

When you are looking to carry around your camera, you need to factor its weight and measurements. The Panasonic GM1 offers external dimensions of 99mm x 55mm x 30mm (3.9" x 2.2" x 1.2") accompanied by a weight of 204 grams (0.45 lbs) whilst the Sigma fp has proportions of 113mm x 70mm x 45mm (4.4" x 2.8" x 1.8") with a weight of 422 grams (0.93 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you have attached during that time. Underneath is the front view over all size comparison of the GM1 compared to the fp.

Using size and weight, the portability grade of the GM1 and fp is 93 and 84 respectively.

Oftentimes, it can be hard to picture the difference between sensor sizes merely by going over technical specs. The picture below will provide you a clearer sense of the sensor sizes in the GM1 and fp.

As you have seen, both the cameras have got different megapixels and different sensor sizes. The GM1 having a tinier sensor is going to make achieving shallower DOF more challenging and the Sigma fp will offer you greater detail with its extra 9MP. Greater resolution will make it easier to crop images much more aggressively. The more aged GM1 is going to be disadvantaged with regard to sensor tech.
