Olympus E-P5 vs Pentax Q-S1

On this page, we will be contrasting the Olympus E-P5 versus Pentax Q-S1, both Entry-Level Mirrorless digital cameras by brands Olympus and Pentax. There exists a noticeable gap between the image resolutions of the E-P5 (16MP) and Q-S1 (12MP) and the E-P5 (Four Thirds) and Q-S1 (1/1.7") boast totally different sensor dimensions.

The E-P5 was revealed 10 months before the Q-S1 and they are both of a similar age. The two cameras have the same body design (Rangefinder-style mirrorless).

Before going into a in-depth comparison, here is a short summary of how the E-P5 matches up against the Q-S1 with regard to portability, imaging, features and an overall grade.

The following is a preview of the gallery images for Olympus PEN E-P5 & Pentax Q-S1. The full galleries are available at Olympus E-P5 Gallery & Pentax Q-S1 Gallery.

If you're intending to lug around your camera, you will want to consider its weight and proportions.

Keep in mind, the weight of an ILC will vary based on the lens you select at that moment. Here is a front view overall size comparison of the E-P5 vs the Q-S1.

Considering dimensions and weight, the portability rating of the E-P5 and Q-S1 is 85 and 92 respectively.

Normally, it is very difficult to see the contrast between sensor measurements simply by going over technical specs. The visual here should provide you a better sense of the sensor measurements in the E-P5 and Q-S1.

As you have seen, both of the cameras provide different megapixels and different sensor measurements. The E-P5 with its bigger sensor will make achieving shallower DOF simpler and the Olympus E-P5 will deliver greater detail because of its extra 4MP. Higher resolution will let you crop shots more aggressively. The older E-P5 is going to be disadvantaged with regard to sensor innovation.
