Olympus E-P3 vs Panasonic FZ300

Following is a in-depth comparison of the Olympus E-P3 and Panasonic FZ300, one is a Entry-Level Mirrorless and the latter is a Small Sensor Superzoom by companies Olympus and Panasonic. The image resolution of the E-P3 (12MP) and the FZ300 (12MP) is relatively close but the E-P3 (Four Thirds) and FZ300 (1/2.3") posses totally different sensor sizes.

The E-P3 was revealed 4 years earlier than the FZ300 which is a fairly large gap as far as camera tech is concerned. Each of these cameras feature different body design with the Olympus E-P3 being a Rangefinder-style mirrorless camera and the Panasonic FZ300 being a SLR-like (bridge) camera.

Before getting into a complete comparison, here is a short summary of how the E-P3 scores vs the FZ300 with regard to portability, imaging, features and an overall score.

The following is a preview of the gallery photos for Olympus PEN E-P3 and Panasonic Lumix DMC-FZ300. The full galleries are viewable at Olympus E-P3 Gallery and Panasonic FZ300 Gallery.

For anyone who is going to carry around your camera often, you'll need to think about its weight and volume. The Olympus E-P3 features physical dimensions of 122mm x 69mm x 34mm (4.8" x 2.7" x 1.3") along with a weight of 369 grams (0.81 lbs) and the Panasonic FZ300 has sizing of 132mm x 92mm x 117mm (5.2" x 3.6" x 4.6") along with a weight of 691 grams (1.52 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will vary depending on the lens you are employing at that moment. Following is a front view measurement comparison of the E-P3 vs the FZ300.

Considering size and weight, the portability grade of the E-P3 and FZ300 is 86 and 59 respectively.

Oftentimes, its difficult to see the gap in sensor sizes purely by looking through technical specs. The pic here might provide you a far better sense of the sensor dimensions in the E-P3 and FZ300.

As you can tell, both of the cameras come with the identical resolution albeit not the same sensor sizes. The E-P3 comes with the bigger sensor which should make achieving shallower depth of field easier. The more aged E-P3 will be disadvantaged with regard to sensor innovation.
