Pentax Q10 vs Sigma Quattro

Here, we will be comparing the Pentax Q10 versus Sigma Quattro, one being a Entry-Level Mirrorless and the latter is a Advanced Mirrorless by companies Pentax and Sigma. There is a crucial difference among the resolutions of the Q10 (12MP) and Quattro (29MP) and the Q10 (1/2.3") and Quattro (APS-C) have different sensor size.

The Q10 was revealed 4 years before the Quattro and that is a fairly serious gap as far as camera tech is concerned. Both the cameras feature the same body design (Rangefinder-style mirrorless).

Before going straight to a full comparison, here is a quick overview of how the Q10 scores against the Quattro with regards to portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Pentax Q10 and Sigma sd Quattro. The full galleries are viewable at Pentax Q10 Gallery and Sigma Quattro Gallery.

When you are going to lug around your camera regularly, you have to consider its weight and dimensions. The Pentax Q10 has physical measurements of 102mm x 58mm x 34mm (4.0" x 2.3" x 1.3") having a weight of 200 grams (0.44 lbs) whilst the Sigma Quattro has dimensions of 147mm x 95mm x 91mm (5.8" x 3.7" x 3.6") having a weight of 625 grams (1.38 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will vary dependant on the lens you choose at that time. Underneath is a front view proportions comparison of the Q10 and the Quattro.

Using size and weight, the portability grade of the Q10 and Quattro is 92 and 63 respectively.

Oftentimes, it is hard to imagine the difference in sensor measurements just by seeing technical specs. The photograph underneath will provide you a much better sense of the sensor measurements in the Q10 and Quattro.

As you have seen, the 2 cameras come with different megapixel count and different sensor measurements. The Q10 with its smaller sensor is going to make getting shallower depth of field harder and the Sigma Quattro will provide greater detail because of its extra 17 Megapixels. Higher resolution will allow you to crop shots a good deal more aggressively. The older Q10 will be disadvantaged when it comes to sensor tech.
