Olympus PEN-F vs Pentax K100D S

Let's look a bit more closely at the Olympus PEN-F vs Pentax K100D S, one is a Advanced Mirrorless and the latter is a Entry-Level DSLR by manufacturers Olympus and Pentax. There exists a significant gap between the sensor resolutions of the PEN-F (20MP) and K100D S (6MP) and the PEN-F (Four Thirds) and K100D S (APS-C) have different sensor measurements.

The PEN-F was unveiled 8 years after the K100D S which is quite a sizable gap as far as technology is concerned. Both of the cameras feature different body design with the Olympus PEN-F being a Rangefinder-style mirrorless camera and the Pentax K100D S being a Compact SLR camera.

Before we go straight to a in depth comparison, here is a brief overview of how the PEN-F grades vs the K100D S for portability, imaging, features and an overall mark.

This is a preview of the gallery photos for Olympus PEN-F and Pentax K100D Super. The full galleries are available at Olympus PEN-F Gallery and Pentax K100D S Gallery.

In case you're aiming to travel with your camera often, you need to factor its weight and proportions.

Bear in mind, the weight of an Interchangeable Lens Camera will differ based on the lens you have attached at that moment. Following is a front view over all size comparison of the PEN-F and the K100D S.

Looking at dimensions and weight, the portability score of the PEN-F and K100D S is 84 and 65 respectively.

Quite often, it is very tough to picture the difference between sensor dimensions just by going over specifications. The picture below will help provide you a far better sense of the sensor sizing in the PEN-F and K100D S.

To sum up, both the cameras feature different megapixel count and different sensor dimensions. The PEN-F with its tinier sensor is going to make achieving shallower DOF harder and the Olympus PEN-F will deliver more detail having an extra 14 Megapixels. Higher resolution will let you crop pictures way more aggressively. The more modern PEN-F should have an advantage in sensor innovation.
