Olympus E-P2 vs Pentax WG-3

Its time to look a bit more closely at the Olympus E-P2 versus Pentax WG-3, one being a Entry-Level Mirrorless and the latter is a Waterproof by companies Olympus and Pentax. There is a big difference between the sensor resolutions of the E-P2 (12MP) and WG-3 (16MP) and the E-P2 (Four Thirds) and WG-3 (1/2.3") have different sensor measurements.

Photography Glossary

The E-P2 was introduced 4 years earlier than the WG-3 and that is quite a big gap as far as tech is concerned. Both of the cameras feature different body design with the Olympus E-P2 being a Rangefinder-style mirrorless camera and the Pentax WG-3 being a Compact camera.

Before we go into a full comparison, here is a simple summary of how the E-P2 matches up versus the WG-3 with respect to portability, imaging, features and an overall rating.

Below is a preview of the gallery photos for Olympus PEN E-P2 and Pentax WG-3. The whole galleries are provided at Olympus E-P2 Gallery and Pentax WG-3 Gallery.

If you're intending to carry your camera regularly, you have to factor in its weight and size. The Olympus E-P2 has exterior dimensions of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") with a weight of 355 grams (0.78 lbs) while the Pentax WG-3 has specifications of 124mm x 64mm x 33mm (4.9" x 2.5" x 1.3") having a weight of 230 grams (0.51 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will change depending on the lens you select at that time. The following is a front view dimension comparison of the E-P2 against the WG-3.

Taking into consideration size and weight, the portability score of the E-P2 and WG-3 is 86 and 90 respectively.

Generally, it's difficult to visualize the contrast between sensor sizing merely by reading through a spec sheet. The graphic below will give you a more clear sense of the sensor sizes in the E-P2 and WG-3.

Clearly, both of those cameras feature different megapixel count and different sensor sizing. The E-P2 using its bigger sensor is going to make shooting bokeh easier and the Pentax WG-3 will give extra detail using its extra 4MP. Higher resolution can also enable you to crop pictures way more aggressively. The older E-P2 is going to be behind in sensor tech.
