The 1s was revealed 5 years later than the GH1 and that is quite a significant difference as far as technology is concerned. Each of these cameras offer different body type with the Olympus 1s being a SLR-like (bridge) camera and the Panasonic GH1 being a SLR-style mirrorless camera.

Before delving through a thorough comparison, below is a simple synopsis of how the 1s scores against the GH1 with regard to portability, imaging, features and an overall grade.

Following is a preview of the gallery photos for Olympus Stylus 1s & Panasonic Lumix DMC-GH1. The full galleries are provided at Olympus 1s Gallery & Panasonic GH1 Gallery.

For anyone who is planning to lug around your camera regularly, you will have to factor in its weight and proportions.

Quite often, it is hard to see the difference between sensor measurements merely by going over technical specs. The graphic underneath may give you a stronger sense of the sensor sizes in the 1s and GH1.

As you can tell, each of the cameras offer the same exact megapixel count albeit not the same sensor measurements. The 1s comes with the tinier sensor which will make achieving shallower DOF more challenging. The younger 1s will have a benefit in sensor technology.
