Olympus E-PL9 vs Pentax K-01

Its time to look much closer at the Olympus E-PL9 versus Pentax K-01, both Entry-Level Mirrorless digital cameras by competitors Olympus and Pentax. The sensor resolution of the E-PL9 (16MP) and the K-01 (16MP) is pretty similar but the E-PL9 (Four Thirds) and K-01 (APS-C) feature totally different sensor sizes.

The E-PL9 was introduced 5 years after the K-01 which is quite a sizable difference as far as tech is concerned. Both of these cameras offer different body type with the Olympus E-PL9 being a Rangefinder-style mirrorless camera and the Pentax K-01 being a SLR-style mirrorless camera.

Before diving straight into a full comparison, below is a quick highlight of how the E-PL9 matches up against the K-01 in relation to portability, imaging, features and an overall score.

Take into consideration, the weight of an ILC will vary based on the lens you are using during that time. The following is the front view dimensions comparison of the E-PL9 vs the K-01.

Considering size and weight, the portability grade of the E-PL9 and K-01 is 85 and 76 respectively.

Generally, it's tough to visualise the gap between sensor sizes only by going over technical specs. The pic here might give you a greater sense of the sensor sizing in the E-PL9 and K-01.

As you have seen, each of these cameras enjoy the same exact resolution albeit not the same sensor sizes. The E-PL9 has got the tinier sensor which should make obtaining shallower depth of field more challenging. The younger E-PL9 will have an advantage in sensor innovation.
