Olympus E-P1 vs Olympus TG-3

Its time to look a bit more closely at the Olympus E-P1 versus Olympus TG-3, former being a Entry-Level Mirrorless while the latter is a Waterproof and both are offered by Olympus. There is a substantial difference between the sensor resolutions of the E-P1 (12MP) and TG-3 (16MP) and the E-P1 (Four Thirds) and TG-3 (1/2.3") boast totally different sensor sizing.

The E-P1 was introduced 5 years before the TG-3 and that is quite a big difference as far as tech is concerned. Each of these cameras have different body design with the Olympus E-P1 being a Rangefinder-style mirrorless camera and the Olympus TG-3 being a Compact camera.

Before going into a step-by-step comparison, here is a short summary of how the E-P1 grades vs the TG-3 in the way of portability, imaging, features and an overall rating.

Generally, it can be hard to envision the difference between sensor sizing just by reading through specs. The photograph underneath will help give you a more clear sense of the sensor dimensions in the E-P1 and TG-3.

All in all, both the cameras provide different megapixel count and different sensor sizing. The E-P1 using its bigger sensor will make achieving shallower depth of field less difficult and the Olympus TG-3 will give more detail using its extra 4MP. Higher resolution can also let you crop shots more aggressively. The older E-P1 is going to be disadvantaged in sensor tech.
