Pentax Q vs Pentax Q-S1 Overview

Let's look a little more in depth at the Pentax Q and Pentax Q-S1, both Entry-Level Mirrorless cameras and they are both designed by Pentax. The sensor resolution of the Q (12MP) and the Q-S1 (12MP) is very close but the Q (1/2.3") and Q-S1 (1/1.7") possess totally different sensor dimensions.

The Q was manufactured 4 years prior to the Q-S1 which is a fairly serious gap as far as camera tech is concerned. Both the cameras come with the identical body type (Rangefinder-style mirrorless).

Before going in to a comprehensive comparison, below is a quick synopsis of how the Q scores versus the Q-S1 when it comes to portability, imaging, features and an overall score.

Pentax Q vs Pentax Q-S1 Sensor Comparison

Often, it is difficult to visualise the contrast in sensor sizes just by looking through a spec sheet. The pic here will help provide you a clearer sense of the sensor dimensions in the Q and Q-S1.

As you can see, the 2 cameras posses the exact same resolution but not the same sensor sizes. The Q provides the smaller sensor which is going to make achieving shallow depth of field tougher. The more aged Q will be disadvantaged in sensor innovation.
