Olympus E-P2 vs Pentax K-3 II

In this write-up, we are reviewing the Olympus E-P2 versus Pentax K-3 II, former being a Entry-Level Mirrorless while the other is a Advanced DSLR by competitors Olympus and Pentax. There exists a substantial gap between the sensor resolutions of the E-P2 (12MP) and K-3 II (24MP) and the E-P2 (Four Thirds) and K-3 II (APS-C) enjoy totally different sensor dimensions.

The E-P2 was released 6 years before the K-3 II and that is quite a big difference as far as technology is concerned. Both of the cameras offer different body type with the Olympus E-P2 being a Rangefinder-style mirrorless camera and the Pentax K-3 II being a Mid-size SLR camera.

Before diving in to a in depth comparison, below is a quick view of how the E-P2 scores versus the K-3 II with respect to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Olympus PEN E-P2 & Pentax K-3 II. The complete galleries are viewable at Olympus E-P2 Gallery & Pentax K-3 II Gallery.

If you're looking to carry your camera, you're going to have to think about its weight and measurements. The Olympus E-P2 has got external measurements of 121mm x 70mm x 36mm (4.8" x 2.8" x 1.4") accompanied by a weight of 355 grams (0.78 lbs) whilst the Pentax K-3 II has proportions of 131mm x 100mm x 77mm (5.2" x 3.9" x 3.0") having a weight of 800 grams (1.76 lbs).

Take into consideration, the weight of an ILC will vary based on the lens you choose at that time. Below is the front view size comparison of the E-P2 compared to the K-3 II.

Taking into consideration dimensions and weight, the portability score of the E-P2 and K-3 II is 86 and 59 respectively.

More often than not, it can be tough to envision the gap between sensor sizing only by reading through technical specs. The graphic below might provide you a much better sense of the sensor sizing in the E-P2 and K-3 II.

As you have seen, both of these cameras enjoy different megapixel count and different sensor sizing. The E-P2 featuring a tinier sensor will make shooting shallow depth of field more challenging and the Pentax K-3 II will resolve extra detail as a result of its extra 12MP. Greater resolution will also make it easier to crop images far more aggressively. The older E-P2 is going to be disadvantaged when it comes to sensor tech.
