Sora from OpenAI releases its first ever music video Pentax S1 vs Pentax Q-S1 Overview
On this page, we are evaluating the Pentax S1 and Pentax Q-S1, one being a Small Sensor Compact and the other is a Entry-Level Mirrorless and they are both built by Pentax. The sensor resolution of the S1 (14MP) and the Q-S1 (12MP) is fairly well matched but the S1 (1/2.3") and Q-S1 (1/1.7") provide different sensor measurements.
Snapchat Adds Watermarks to AI-Created ImagesThe S1 was released 4 years before the Q-S1 and that is quite a large gap as far as technology is concerned. Both of the cameras have different body design with the Pentax S1 being a Compact camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.
Before delving right into a full comparison, here is a simple highlight of how the S1 scores against the Q-S1 in terms of portability, imaging, features and an overall grade.

Pentax S1 vs Pentax Q-S1 Sensor Comparison
Normally, it is difficult to imagine the contrast between sensor measurements just by checking a spec sheet. The graphic here might provide you a clearer sense of the sensor dimensions in the S1 and Q-S1.
Clearly, each of the cameras provide different resolutions and different sensor measurements. The S1 due to its tinier sensor is going to make achieving shallow DOF more difficult and the Pentax S1 will resolve extra detail as a result of its extra 2 Megapixels. Greater resolution will also allow you to crop pics more aggressively. The older S1 is going to be disadvantaged with regard to sensor tech.
