Panasonic G100 vs Panasonic GM1

Here is a thorough overview of the Panasonic G100 vs Panasonic GM1, both Entry-Level Mirrorless digital cameras and they are both designed by Panasonic. There exists a huge gap between the resolutions of the G100 (20MP) and GM1 (16MP) but they use the exact same sensor measurements (Four Thirds).

The G100 was manufactured 6 years later than the GM1 and that is quite a significant gap as far as technology is concerned. Both cameras come with different body type with the Panasonic G100 being a SLR-style mirrorless camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before we go straight into a complete comparison, below is a concise summary of how the G100 scores vs the GM1 with regard to portability, imaging, features and an overall rating.

Normally, it can be difficult to envision the gap between sensor sizing purely by looking at a spec sheet. The photograph here will give you a more clear sense of the sensor measurements in the G100 and GM1.

As you can see, both of the cameras posses the exact same sensor measurements albeit not the same megapixels. You should count on the Panasonic G100 to give you more detail due to its extra 4 Megapixels. Higher resolution will also make it easier to crop shots somewhat more aggressively. The more recent G100 is going to have a benefit in sensor innovation.
