Leica M9 vs Sony A7S II

Lets take a more detailed look at the Leica M9 versus Sony A7S II, both Pro Mirrorless cameras by manufacturers Leica and Sony. There is a significant difference among the sensor resolutions of the M9 (18MP) and A7S II (12MP) but they enjoy the same exact sensor size (Full frame).

The M9 was introduced 7 years earlier than the A7S II which is a fairly sizable gap as far as camera tech is concerned. The two cameras offer different body type with the Leica M9 being a Rangefinder-style mirrorless camera and the Sony A7S II being a SLR-style mirrorless camera.

Before diving through a comprehensive comparison, below is a quick highlight of how the M9 grades versus the A7S II for portability, imaging, features and an overall score.

The following is a preview of the gallery photos for Leica M9 and Sony Alpha A7S II. The whole galleries are provided at Leica M9 Gallery and Sony A7S II Gallery.

If you are intending to carry around your camera frequently, you'll have to take into account its weight and proportions. The Leica M9 features outside dimensions of 139mm x 80mm x 37mm (5.5" x 3.1" x 1.5") having a weight of 585 grams (1.29 lbs) while the Sony A7S II has measurements of 127mm x 96mm x 60mm (5.0" x 3.8" x 2.4") along with a weight of 627 grams (1.38 lbs).

Remember, the weight of an Interchangeable Lens Camera will change based on the lens you are utilising at that moment. Below is the front view proportions comparison of the M9 and the A7S II.

Taking into account size and weight, the portability score of the M9 and A7S II is 79 and 68 respectively.

Generally, it can be hard to envision the gap in sensor sizes merely by researching technical specs. The pic below may provide you a far better sense of the sensor sizes in the M9 and A7S II.

As you have seen, both the cameras enjoy the same exact sensor sizing albeit not the same resolution. You should count on the Leica M9 to result in greater detail using its extra 6 Megapixels. Higher resolution can also make it easier to crop shots far more aggressively. The more aged M9 will be behind in sensor innovation.
