The GH1 was revealed 6 years before the GM5 and that is quite a significant gap as far as tech is concerned. Both of these cameras come with different body type with the Panasonic GH1 being a SLR-style mirrorless camera and the Panasonic GM5 being a Rangefinder-style mirrorless camera.

Before we go through a complete comparison, below is a concise summary of how the GH1 scores vs the GM5 with regards to portability, imaging, features and an overall grade.

Usually, it can be difficult to see the gap between sensor measurements just by reading technical specs. The graphic here may provide you a stronger sense of the sensor measurements in the GH1 and GM5.

As you can tell, both of those cameras posses the exact same sensor measurements but not the same resolution. You should expect to see the Panasonic GM5 to offer you greater detail because of its extra 4 Megapixels. Greater resolution will also help you crop photos somewhat more aggressively. The older GH1 is going to be disadvantaged in sensor tech.
