The GH1 was unveiled 5 years before the GM1 and that is quite a big gap as far as tech is concerned. Each of these cameras have different body design with the Panasonic GH1 being a SLR-style mirrorless camera and the Panasonic GM1 being a Rangefinder-style mirrorless camera.

Before we go right into a detailed comparison, here is a quick overview of how the GH1 grades against the GM1 with regards to portability, imaging, features and an overall grade.

All in all, both of the cameras provide the same sensor dimensions albeit not the same megapixels. You should count on the Panasonic GM1 to offer greater detail having an extra 4MP. Higher resolution will enable you to crop pictures more aggressively. The older GH1 is going to be behind when it comes to sensor technology.
