Olympus TG-870 vs Pentax Q7

Below, we are reviewing the Olympus TG-870 and Pentax Q7, one being a Ultracompact and the other is a Entry-Level Mirrorless by competitors Olympus and Pentax. There is a huge difference between the sensor resolutions of the TG-870 (16MP) and Q7 (12MP) and the TG-870 (1/2.3") and Q7 (1/1.7") feature different sensor size.

The TG-870 was unveiled 2 years later than the Q7 and that is quite a significant gap as far as tech is concerned. Both cameras come with different body type with the Olympus TG-870 being a Ultracompact camera and the Pentax Q7 being a Rangefinder-style mirrorless camera.

Before getting straight into a complete comparison, below is a short summation of how the TG-870 matches up versus the Q7 when considering portability, imaging, features and an overall grade.

Factoring in size and weight, the portability rating of the TG-870 and Q7 is 91 and 92 respectively.

Often, it is difficult to imagine the contrast between sensor measurements simply by checking specifications. The photograph below will help give you a stronger sense of the sensor dimensions in the TG-870 and Q7.

Plainly, both of the cameras have got different megapixels and different sensor measurements. The TG-870 with its tinier sensor is going to make shooting shallower DOF harder and the Olympus TG-870 will give extra detail having an extra 4MP. Greater resolution can also make it easier to crop pics much more aggressively. The younger TG-870 should have an advantage in sensor tech.
