Leica M9 vs Sony A7 II

In this write-up, we are evaluating the Leica M9 versus Sony A7 II, both Pro Mirrorless digital cameras by brands Leica and Sony. There exists a substantial gap between the image resolutions of the M9 (18MP) and A7 II (24MP) but they feature the same exact sensor size (Full frame).

The M9 was brought out 6 years earlier than the A7 II and that is quite a big difference as far as technology is concerned. Both cameras offer different body type with the Leica M9 being a Rangefinder-style mirrorless camera and the Sony A7 II being a SLR-style mirrorless camera.

Before delving through a complete comparison, below is a quick introduction of how the M9 matches up against the A7 II in relation to portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Leica M9 & Sony Alpha A7 II. The entire galleries are viewable at Leica M9 Gallery & Sony A7 II Gallery.

When you are planning to lug around your camera often, you should think about its weight and measurements. The Leica M9 comes with physical measurements of 139mm x 80mm x 37mm (5.5" x 3.1" x 1.5") having a weight of 585 grams (1.29 lbs) and the Sony A7 II has proportions of 127mm x 96mm x 60mm (5.0" x 3.8" x 2.4") and a weight of 599 grams (1.32 lbs).

Keep in mind, the weight of an ILC will change depending on the lens you select at that time. Here is the front view sizing comparison of the M9 and the A7 II.

Taking into account dimensions and weight, the portability rating of the M9 and A7 II is 79 and 69 respectively.

More often than not, it is very tough to envision the gap between sensor measurements purely by checking technical specs. The photograph underneath may offer you a better sense of the sensor measurements in the M9 and A7 II.

As you can tell, each of the cameras offer the same exact sensor sizing but not the same resolution. You can anticipate the Sony A7 II to resolve extra detail having its extra 6MP. Greater resolution will help you crop photos a little more aggressively. The older M9 is going to be disadvantaged with regard to sensor technology.
