Pentax H90 vs Pentax Q-S1

Let's look much closer at the Pentax H90 and Pentax Q-S1, former being a Small Sensor Compact while the other is a Entry-Level Mirrorless and they are both offered by Pentax. The sensor resolution of the H90 (12MP) and the Q-S1 (12MP) is fairly well matched but the H90 (1/2.3") and Q-S1 (1/1.7") enjoy totally different sensor size.

The H90 was unveiled 5 years earlier than the Q-S1 and that is quite a large difference as far as tech is concerned. Each of the cameras come with different body type with the Pentax H90 being a Compact camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.

Before we go straight into a full comparison, below is a quick summary of how the H90 scores versus the Q-S1 in terms of portability, imaging, features and an overall grade.

For anyone who is going to lug around your camera, you are going to need to think about its weight and dimensions. The Pentax H90 offers physical measurements of 101mm x 65mm x 28mm (4.0" x 2.6" x 1.1") along with a weight of 153 grams (0.34 lbs) whilst the Pentax Q-S1 has dimensions of 105mm x 58mm x 34mm (4.1" x 2.3" x 1.3") along with a weight of 203 grams (0.45 lbs).

Always remember, the weight of an ILC will change depending on the lens you use during that time. Here is the front view scale comparison of the H90 vs the Q-S1.

Taking into consideration size and weight, the portability rating of the H90 and Q-S1 is 93 and 92 respectively.

In many cases, it can be tough to see the contrast between sensor measurements purely by reading through technical specs. The photograph below should give you a far better sense of the sensor sizing in the H90 and Q-S1.

As you have seen, both of the cameras have got the exact same resolution but not the same sensor measurements. The H90 has the tinier sensor which will make achieving shallow depth of field tougher. The older H90 is going to be disadvantaged when it comes to sensor tech.
