Olympus E-PM2 vs Pentax K20D

Let's take a more detailed look at the Olympus E-PM2 and Pentax K20D, former is a Entry-Level Mirrorless while the latter is a Advanced DSLR by brands Olympus and Pentax. The resolution of the E-PM2 (16MP) and the K20D (15MP) is pretty well matched but the E-PM2 (Four Thirds) and K20D (APS-C) offer totally different sensor sizes.

The E-PM2 was unveiled 4 years after the K20D which is quite a big difference as far as technology is concerned. Each of the cameras have different body design with the Olympus E-PM2 being a Rangefinder-style mirrorless camera and the Pentax K20D being a Mid-size SLR camera.

Before diving straight to a in-depth comparison, here is a quick summary of how the E-PM2 matches up against the K20D for portability, imaging, features and an overall mark.

This is a preview of the gallery images for Olympus PEN E-PM2 & Pentax K20D. The full galleries are provided at Olympus E-PM2 Gallery & Pentax K20D Gallery.

If you are aiming to travel with your camera often, you have to factor in its weight and proportions. The Olympus E-PM2 has got outer dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") having a weight of 269 grams (0.59 lbs) while the Pentax K20D has measurements of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") along with a weight of 800 grams (1.76 lbs).

Take into consideration, the weight of an ILC will differ dependant on the lens you have at the time. Underneath is a front view measurement comparison of the E-PM2 and the K20D.

Considering dimensions and weight, the portability rating of the E-PM2 and K20D is 89 and 59 respectively.

Normally, it can be difficult to visualise the difference between sensor dimensions simply by reading through a spec sheet. The picture here will offer you a greater sense of the sensor dimensions in the E-PM2 and K20D.

As you can see, both of those cameras have different megapixel count and different sensor dimensions. The E-PM2 having a tinier sensor will make getting bokeh harder and the Olympus E-PM2 will give you extra detail having an extra 1 Megapixels. Higher resolution will also allow you to crop photographs a bit more aggressively. The fresher E-PM2 is going to have an edge in sensor technology.
