Pentax W90 vs Pentax Q-S1

Below, we are contrasting the Pentax W90 and Pentax Q-S1, one is a Waterproof and the other is a Entry-Level Mirrorless and both of them are designed by Pentax. The resolution of the W90 (12MP) and the Q-S1 (12MP) is very close but the W90 (1/2.3") and Q-S1 (1/1.7") feature totally different sensor sizing.

The W90 was brought out 5 years prior to the Q-S1 which is a fairly large gap as far as camera tech is concerned. Both of these cameras come with different body type with the Pentax W90 being a Compact camera and the Pentax Q-S1 being a Rangefinder-style mirrorless camera.

Before we go in to a comprehensive comparison, below is a simple introduction of how the W90 grades versus the Q-S1 in relation to portability, imaging, features and an overall score.

The following is a sample of the gallery pics for Pentax Optio W90 and Pentax Q-S1. The entire galleries are provided at Pentax W90 Gallery and Pentax Q-S1 Gallery.

If you are looking to carry around your camera often, you are going to need to think about its weight and proportions. The Pentax W90 comes with outside dimensions of 108mm x 59mm x 25mm (4.3" x 2.3" x 1.0") with a weight of 164 grams (0.36 lbs) and the Pentax Q-S1 has measurements of 105mm x 58mm x 34mm (4.1" x 2.3" x 1.3") accompanied by a weight of 203 grams (0.45 lbs).

Do not forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you are utilising during that time. Here is the front view measurement comparison of the W90 against the Q-S1.

Taking into account size and weight, the portability grade of the W90 and Q-S1 is 94 and 92 respectively.

Oftentimes, it's tough to envision the contrast in sensor sizes merely by looking through specifications. The pic below might provide you a more clear sense of the sensor dimensions in the W90 and Q-S1.

Plainly, both of those cameras posses the exact same MP but not the same sensor sizes. The W90 includes the smaller sensor which is going to make achieving shallow DOF more challenging. The more aged W90 will be disadvantaged when it comes to sensor tech.
