The GM1 was released 12 months later than the ZS25 so they are both of a similar generation. Both cameras have different body design with the Panasonic GM1 being a Rangefinder-style mirrorless camera and the Panasonic ZS25 being a Compact camera.

Before going right into a thorough comparison, here is a quick synopsis of how the GM1 matches up against the ZS25 in regards to portability, imaging, features and an overall rating.

The following is a preview of the gallery images for Panasonic Lumix DMC-GM1 and Panasonic Lumix DMC-ZS25. The complete galleries are viewable at Panasonic GM1 Gallery and Panasonic ZS25 Gallery.

Generally, it is very tough to picture the difference in sensor sizing merely by seeing technical specs. The photograph here should give you a far better sense of the sensor sizes in the GM1 and ZS25.

As you can tell, both cameras provide the same MP albeit different sensor sizing. The GM1 has the bigger sensor which will make obtaining shallow DOF simpler. The younger GM1 should have a benefit in sensor innovation.
