Pentax Q-S1 vs Sigma fp

On this page, we will be reviewing the Pentax Q-S1 vs Sigma fp, one being a Entry-Level Mirrorless and the latter is a Advanced Mirrorless by manufacturers Pentax and Sigma. There exists a huge gap among the resolutions of the Q-S1 (12MP) and fp (25MP) and the Q-S1 (1/1.7") and fp (Full frame) have different sensor measurements.

The Q-S1 was released 6 years prior to the fp and that is a fairly significant gap as far as camera technology is concerned. The two cameras have the same body design (Rangefinder-style mirrorless).

Before delving right into a full comparison, here is a short highlight of how the Q-S1 matches up versus the fp in regards to portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Pentax Q-S1 and Sigma fp. The complete galleries are available at Pentax Q-S1 Gallery and Sigma fp Gallery.

If you're planning to lug around your camera often, you will want to consider its weight and size. The Pentax Q-S1 provides exterior measurements of 105mm x 58mm x 34mm (4.1" x 2.3" x 1.3") along with a weight of 203 grams (0.45 lbs) whilst the Sigma fp has specifications of 113mm x 70mm x 45mm (4.4" x 2.8" x 1.8") and a weight of 422 grams (0.93 lbs).

Take into consideration, the weight of an Interchangeable Lens Camera will differ depending on the lens you are using at that time. Following is a front view over all size comparison of the Q-S1 vs the fp.

Taking into account dimensions and weight, the portability grade of the Q-S1 and fp is 92 and 84 respectively.

Quite often, it is difficult to picture the contrast in sensor measurements merely by seeing specifications. The graphic here will provide you a more clear sense of the sensor measurements in the Q-S1 and fp.

Plainly, the 2 cameras provide different megapixels and different sensor measurements. The Q-S1 because of its smaller sensor is going to make achieving shallow DOF trickier and the Sigma fp will show more detail as a result of its extra 13MP. Higher resolution will help you crop pictures more aggressively. The older Q-S1 will be disadvantaged with regard to sensor innovation.
