Olympus E-PM1 vs Pentax KP

Its time to look a bit more closely at the Olympus E-PM1 vs Pentax KP, one being a Entry-Level Mirrorless and the latter is a Advanced DSLR by companies Olympus and Pentax. There is a huge difference between the sensor resolutions of the E-PM1 (12MP) and KP (24MP) and the E-PM1 (Four Thirds) and KP (APS-C) offer totally different sensor measurements.

The E-PM1 was manufactured 6 years before the KP and that is quite a significant gap as far as tech is concerned. Each of the cameras feature different body design with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Pentax KP being a Mid-size SLR camera.

Before going straight to a thorough comparison, here is a concise synopsis of how the E-PM1 matches up vs the KP in the way of portability, imaging, features and an overall rating.

This is a preview of the gallery photos for Olympus PEN E-PM1 and Pentax KP. The entire galleries are provided at Olympus E-PM1 Gallery and Pentax KP Gallery.

When you are looking to carry your camera, you have to take into account its weight and measurements. The Olympus E-PM1 enjoys outside measurements of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") accompanied by a weight of 265 grams (0.58 lbs) while the Pentax KP has proportions of 132mm x 101mm x 76mm (5.2" x 4.0" x 3.0") and a weight of 703 grams (1.55 lbs).

Keep in mind, the weight of an Interchangeable Lens Camera will vary based on the lens you have attached at the time. The following is a front view over all size comparison of the E-PM1 compared to the KP.

Looking at size and weight, the portability rating of the E-PM1 and KP is 89 and 61 respectively.

In many cases, it is very hard to envision the gap between sensor sizing only by checking technical specs. The photograph here may give you a stronger sense of the sensor sizing in the E-PM1 and KP.

As you can tell, both of these cameras feature different megapixel count and different sensor sizing. The E-PM1 because of its tinier sensor will make achieving shallow DOF more difficult and the Pentax KP will give more detail due to its extra 12MP. Higher resolution will also let you crop shots way more aggressively. The older E-PM1 is going to be disadvantaged when it comes to sensor technology.
