The E-P3 was revealed 3 years before the TG-3 which is quite a large difference as far as tech is concerned. Both of the cameras offer different body type with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Olympus TG-3 being a Compact camera.

Before going straight into a detailed comparison, below is a brief highlight of how the E-P3 matches up vs the TG-3 when considering portability, imaging, features and an overall mark.

Here is a sample of the gallery pics for Olympus PEN E-P3 & Olympus Tough TG-3. The full galleries are provided at Olympus E-P3 Gallery & Olympus TG-3 Gallery.

Clearly, both of those cameras enjoy different megapixels and different sensor dimensions. The E-P3 using its larger sensor will make shooting shallow DOF simpler and the Olympus TG-3 will offer you greater detail because of its extra 4MP. Greater resolution can also make it easier to crop images far more aggressively. The more aged E-P3 is going to be disadvantaged with regard to sensor tech.
