Pentax Q7 vs Sony T900

Let's take a more detailed look at the Pentax Q7 versus Sony T900, one is a Entry-Level Mirrorless and the other is a Ultracompact by competitors Pentax and Sony. The resolution of the Q7 (12MP) and the T900 (12MP) is fairly close but the Q7 (1/1.7") and T900 (1/2.3") have totally different sensor size.

The Q7 was released 4 years after the T900 which is a fairly large gap as far as camera tech is concerned. Both of these cameras have different body design with the Pentax Q7 being a Rangefinder-style mirrorless camera and the Sony T900 being a Ultracompact camera.

Before delving into a thorough comparison, here is a simple highlight of how the Q7 grades against the T900 in regards to portability, imaging, features and an overall mark.

Oftentimes, it's difficult to envision the gap in sensor dimensions merely by looking through specifications. The image below will give you a better sense of the sensor dimensions in the Q7 and T900.

To sum up, both cameras provide the same resolution but not the same sensor dimensions. The Q7 has the larger sensor which is going to make achieving shallower depth of field less difficult. The newer Q7 is going to have a benefit with regard to sensor technology.
