Leica M9 vs Pentax Q-S1

Below, we are reviewing the Leica M9 versus Pentax Q-S1, former is a Pro Mirrorless while the other is a Entry-Level Mirrorless by competitors Leica and Pentax. There is a considerable difference between the sensor resolutions of the M9 (18MP) and Q-S1 (12MP) and the M9 (Full frame) and Q-S1 (1/1.7") possess totally different sensor sizing.

The M9 was manufactured 5 years before the Q-S1 which is quite a large difference as far as tech is concerned. Each of these cameras come with the identical body type (Rangefinder-style mirrorless).

Before diving straight into a step-by-step comparison, below is a short view of how the M9 scores versus the Q-S1 in regards to portability, imaging, features and an overall mark.

Here is a sample of the gallery pics for Leica M9 & Pentax Q-S1. The entire galleries are available at Leica M9 Gallery & Pentax Q-S1 Gallery.

For anybody who is planning to travel with your camera frequently, you will want to consider its weight and size.

Using size and weight, the portability rating of the M9 and Q-S1 is 79 and 92 respectively.

Generally, its difficult to envision the difference between sensor dimensions only by checking specs. The picture here may provide you a much better sense of the sensor dimensions in the M9 and Q-S1.

As you can plainly see, both of the cameras posses different megapixels and different sensor dimensions. The M9 because of its larger sensor will make achieving bokeh easier and the Leica M9 will give you greater detail due to its extra 6MP. Greater resolution will enable you to crop photos somewhat more aggressively. The more aged M9 is going to be disadvantaged with regard to sensor innovation.
