Olympus E-PM1 vs Pentax P70

Below, we are contrasting the Olympus E-PM1 versus Pentax P70, former being a Entry-Level Mirrorless while the other is a Ultracompact by competitors Olympus and Pentax. The sensor resolution of the E-PM1 (12MP) and the P70 (12MP) is fairly well matched but the E-PM1 (Four Thirds) and P70 (1/2.3") come with totally different sensor measurements.

The E-PM1 was unveiled 2 years later than the P70 and that is quite a significant difference as far as tech is concerned. Each of the cameras come with different body type with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Pentax P70 being a Ultracompact camera.

Before we go through a thorough comparison, below is a simple synopsis of how the E-PM1 grades versus the P70 in the way of portability, imaging, features and an overall grade.

For anyone who is planning to lug around your camera often, you are going to need to factor in its weight and proportions. The Olympus E-PM1 comes with external dimensions of 110mm x 64mm x 34mm (4.3" x 2.5" x 1.3") along with a weight of 265 grams (0.58 lbs) while the Pentax P70 has measurements of 97mm x 54mm x 22mm (3.8" x 2.1" x 0.9") along with a weight of 155 grams (0.34 lbs).

Remember, the weight of an ILC will vary depending on the lens you have attached at the time. The following is the front view proportions comparison of the E-PM1 against the P70.

Considering size and weight, the portability rating of the E-PM1 and P70 is 89 and 95 respectively.

Usually, its tough to see the difference between sensor measurements only by looking at a spec sheet. The graphic below will help offer you a clearer sense of the sensor sizes in the E-PM1 and P70.

Clearly, both of these cameras have got the exact same resolution but not the same sensor measurements. The E-PM1 uses the larger sensor which is going to make obtaining shallower depth of field easier. The more modern E-PM1 will have an edge with regard to sensor technology.
