Olympus E-P1 vs Pentax WG-2

The following is a comprehensive review of the Olympus E-P1 versus Pentax WG-2, one is a Entry-Level Mirrorless and the latter is a Waterproof by competitors Olympus and Pentax. There is a significant difference among the resolutions of the E-P1 (12MP) and WG-2 (16MP) and the E-P1 (Four Thirds) and WG-2 (1/2.3") use different sensor sizing.

The E-P1 was announced 3 years before the WG-2 which is a fairly sizable gap as far as camera tech is concerned. Both of the cameras come with different body type with the Olympus E-P1 being a Rangefinder-style mirrorless camera and the Pentax WG-2 being a Compact camera.

Before delving through a full comparison, below is a quick highlight of how the E-P1 grades against the WG-2 in relation to portability, imaging, features and an overall mark.

For those who are going to travel with your camera, you'll need to consider its weight and dimensions. The Olympus E-P1 provides outside dimensions of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") along with a weight of 355 grams (0.78 lbs) whilst the Pentax WG-2 has dimensions of 122mm x 61mm x 30mm (4.8" x 2.4" x 1.2") and a weight of 192 grams (0.42 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilising during that time. Here is the front view over all size comparison of the E-P1 compared to the WG-2.

Factoring in size and weight, the portability score of the E-P1 and WG-2 is 86 and 91 respectively.

Oftentimes, its tough to picture the contrast in sensor dimensions simply by viewing technical specs. The picture here should provide you a far better sense of the sensor sizes in the E-P1 and WG-2.

As you can tell, both of those cameras posses different resolutions and different sensor dimensions. The E-P1 having a bigger sensor is going to make achieving shallower DOF easier and the Pentax WG-2 will render more detail with its extra 4 Megapixels. Higher resolution will let you crop photographs somewhat more aggressively. The more aged E-P1 will be disadvantaged when it comes to sensor tech.
