Olympus E-PM1 vs Pentax K10D

In this write-up, we are comparing the Olympus E-PM1 versus Pentax K10D, one being a Entry-Level Mirrorless and the other is a Advanced DSLR by manufacturers Olympus and Pentax. The sensor resolution of the E-PM1 (12MP) and the K10D (10MP) is fairly similar but the E-PM1 (Four Thirds) and K10D (APS-C) use different sensor measurements.

Photography Glossary

The E-PM1 was unveiled 5 years later than the K10D and that is quite a sizable gap as far as tech is concerned. Both of the cameras offer different body type with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Pentax K10D being a Mid-size SLR camera.

Before we go in to a comprehensive comparison, below is a concise summation of how the E-PM1 matches up versus the K10D when considering portability, imaging, features and an overall grade.

The following is a sample of the gallery pictures for Olympus PEN E-PM1 and Pentax K10D. The full galleries are viewable at Olympus E-PM1 Gallery and Pentax K10D Gallery.

In case you're looking to lug around your camera often, you have to take into account its weight and measurements. The Olympus E-PM1 has got exterior dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") and a weight of 265 grams (0.58 lbs) while the Pentax K10D has proportions of 142mm x 101mm x 70mm (5.6" x 4.0" x 2.8") along with a weight of 793 grams (1.75 lbs).

Bear in mind, the weight of an Interchangeable Lens Camera will vary depending on the lens you select at that moment. Below is the front view measurement comparison of the E-PM1 vs the K10D.

Using size and weight, the portability grade of the E-PM1 and K10D is 89 and 59 respectively.

Often, its tough to picture the gap between sensor measurements purely by reading a spec sheet. The photograph here might provide you a clearer sense of the sensor sizes in the E-PM1 and K10D.

Clearly, both of those cameras offer different megapixel count and different sensor measurements. The E-PM1 having a tinier sensor is going to make getting shallow depth of field tougher and the Olympus E-PM1 will deliver extra detail having an extra 2MP. Greater resolution will let you crop images a little more aggressively. The newer E-PM1 provides an advantage when it comes to sensor technology.
