Olympus E-PL7 vs Pentax K20D

Here, we will be contrasting the Olympus E-PL7 vs Pentax K20D, one is a Entry-Level Mirrorless and the latter is a Advanced DSLR by manufacturers Olympus and Pentax. The resolution of the E-PL7 (16MP) and the K20D (15MP) is relatively well matched but the E-PL7 (Four Thirds) and K20D (APS-C) have totally different sensor sizing.

Photography Glossary

The E-PL7 was manufactured 6 years after the K20D which is quite a sizable gap as far as tech is concerned. Both of these cameras feature different body design with the Olympus E-PL7 being a Rangefinder-style mirrorless camera and the Pentax K20D being a Mid-size SLR camera.

Before getting straight to a full comparison, here is a quick introduction of how the E-PL7 scores vs the K20D in relation to portability, imaging, features and an overall mark.

The following is a preview of the gallery photos for Olympus PEN E-PL7 and Pentax K20D. The entire galleries are viewable at Olympus E-PL7 Gallery and Pentax K20D Gallery.

In many cases, it is hard to see the difference between sensor dimensions merely by reading through technical specs. The picture below will provide you a clearer sense of the sensor sizing in the E-PL7 and K20D.

As you can tell, the 2 cameras feature different resolutions and different sensor dimensions. The E-PL7 due to its tinier sensor will make getting shallow depth of field more challenging and the Olympus E-PL7 will resolve extra detail due to its extra 1MP. Higher resolution can also make it easier to crop photographs way more aggressively. The more recent E-PL7 is going to have an advantage when it comes to sensor tech.
