The 1s was introduced 2 years later than the GH3 and that is quite a big gap as far as technology is concerned. Both the cameras come with different body type with the Olympus 1s being a SLR-like (bridge) camera and the Panasonic GH3 being a SLR-style mirrorless camera.

Before going in to a in depth comparison, below is a simple highlight of how the 1s matches up vs the GH3 when considering portability, imaging, features and an overall rating.

Below is a preview of the gallery photos for Olympus Stylus 1s and Panasonic Lumix DMC-GH3. The whole galleries are provided at Olympus 1s Gallery and Panasonic GH3 Gallery.

If you are aiming to carry your camera often, you will need to consider its weight and proportions.

Typically, it can be hard to picture the difference between sensor sizing merely by reading specs. The photograph below will provide you a greater sense of the sensor measurements in the 1s and GH3.

All in all, both cameras have got different resolutions and different sensor sizing. The 1s using its tinier sensor is going to make achieving shallower DOF trickier and the Panasonic GH3 will offer more detail using its extra 4 Megapixels. Higher resolution will also allow you to crop pictures much more aggressively. The more modern 1s should have an advantage with regard to sensor tech.
