Olympus E-PM1 vs Pentax K-7

Lets take a deeper look at the Olympus E-PM1 vs Pentax K-7, one being a Entry-Level Mirrorless and the other is a Advanced DSLR by rivals Olympus and Pentax. The sensor resolution of the E-PM1 (12MP) and the K-7 (15MP) is fairly comparable but the E-PM1 (Four Thirds) and K-7 (APS-C) have totally different sensor sizing.

The E-PM1 was brought out 2 years later than the K-7 and that is a fairly large gap as far as camera technology is concerned. The two cameras have different body design with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Pentax K-7 being a Mid-size SLR camera.

Before we go straight to a full comparison, here is a brief overview of how the E-PM1 matches up against the K-7 in relation to portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Olympus PEN E-PM1 and Pentax K-7. The entire galleries are available at Olympus E-PM1 Gallery and Pentax K-7 Gallery.

When you are aiming to lug around your camera frequently, you'll have to factor in its weight and volume. The Olympus E-PM1 has got exterior dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") having a weight of 265 grams (0.58 lbs) whilst the Pentax K-7 has sizing of 131mm x 97mm x 73mm (5.2" x 3.8" x 2.9") accompanied by a weight of 750 grams (1.65 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary based on the lens you are utilising during that time. The following is a front view size comparison of the E-PM1 versus the K-7.

Looking at dimensions and weight, the portability rating of the E-PM1 and K-7 is 89 and 60 respectively.

Typically, it is difficult to envision the difference in sensor measurements only by going through specifications. The visual below will help offer you a much better sense of the sensor sizes in the E-PM1 and K-7.

To sum up, each of the cameras have different megapixels and different sensor measurements. The E-PM1 because of its smaller sensor will make shooting shallower DOF more difficult and the Pentax K-7 will produce greater detail having its extra 3 Megapixels. Greater resolution will also help you crop photos a bit more aggressively. The younger E-PM1 will have an advantage in sensor technology.
