The G1 was introduced 6 years earlier than the GM5 which is a fairly big gap as far as camera tech is concerned. Each of the cameras come with different body type with the Panasonic G1 being a SLR-style mirrorless camera and the Panasonic GM5 being a Rangefinder-style mirrorless camera.

Before getting straight into a step-by-step comparison, below is a simple highlight of how the G1 scores versus the GM5 in terms of portability, imaging, features and an overall mark.

If you're going to travel with your camera, you will need to think about its weight and proportions.

Oftentimes, it can be hard to visualize the contrast in sensor dimensions just by researching specifications. The picture below may offer you a clearer sense of the sensor sizes in the G1 and GM5.

Plainly, the 2 cameras posses the exact same sensor measurements albeit different MP. You should expect the Panasonic GM5 to result in greater detail using its extra 4 Megapixels. Higher resolution will enable you to crop pictures somewhat more aggressively. The more aged G1 will be disadvantaged with regard to sensor technology.
