The E-M1 was brought out 22 months after the TS20 making them a generation away from each other. Both of these cameras have different body design with the Olympus E-M1 being a SLR-style mirrorless camera and the Panasonic TS20 being a Compact camera.

Before getting straight to a in depth comparison, here is a brief overview of how the E-M1 grades versus the TS20 with regard to portability, imaging, features and an overall mark.

The following is a sample of the gallery pics for Olympus OM-D E-M1 and Panasonic Lumix DMC-TS20. The entire galleries are viewable at Olympus E-M1 Gallery and Panasonic TS20 Gallery.

If you are looking to travel with your camera frequently, you're going to have to take into account its weight and volume.

Oftentimes, it is tough to visualise the difference in sensor dimensions only by researching a spec sheet. The pic underneath will give you a clearer sense of the sensor measurements in the E-M1 and TS20.

As you can see, both of those cameras provide the same resolution but not the same sensor dimensions. The E-M1 has the larger sensor which should make obtaining shallower depth of field easier. The younger E-M1 will have a benefit in sensor technology.
