The E-P3 was introduced 9 years prior to the G100 and that is quite a large gap as far as technology is concerned. Both the cameras offer different body type with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Panasonic G100 being a SLR-style mirrorless camera.

Before getting through a complete comparison, below is a short synopsis of how the E-P3 grades vs the G100 in relation to portability, imaging, features and an overall rating.

The following is a preview of the gallery photos for Olympus PEN E-P3 and Panasonic Lumix DC-G100. The whole galleries are available at Olympus E-P3 Gallery and Panasonic G100 Gallery.

In case you're intending to carry your camera, you'll need to factor in its weight and proportions.

Sometimes, its tough to visualise the gap between sensor sizing just by checking a spec sheet. The photograph here will help offer you a more clear sense of the sensor sizing in the E-P3 and G100.

Clearly, each of these cameras offer the same exact sensor sizing albeit not the same resolution. You should count on the Panasonic G100 to resolve more detail using its extra 8MP. Higher resolution can also help you crop shots a little more aggressively. The older E-P3 is going to be disadvantaged when it comes to sensor tech.
