Oftentimes, it's tough to envision the contrast between sensor measurements simply by going over specs. The visual below will give you a far better sense of the sensor sizing in the GH1 and GM1.

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.
