Here is a in-depth analysis of the Leica M9 versus Sony a1, both Pro Mirrorless digital cameras by rivals Leica and Sony. There is a huge difference between the image resolutions of the M9 (18MP) and a1 (50MP) but they feature the same exact sensor sizing (Full frame).

The M9 was introduced 12 years prior to the a1 and that is quite a significant gap as far as tech is concerned. Each of these cameras offer different body type with the Leica M9 being a Rangefinder-style mirrorless camera and the Sony a1 being a SLR-style mirrorless camera.

Before getting through a full comparison, below is a brief summary of how the M9 grades vs the a1 in regards to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Leica M9 and Sony Alpha a1. The whole galleries are available at Leica M9 Gallery and Sony a1 Gallery.

For anybody who is aiming to carry your camera frequently, you'll have to take into account its weight and dimensions.

In many cases, it is very hard to visualise the gap between sensor sizing purely by checking specifications. The visual below might offer you a stronger sense of the sensor measurements in the M9 and a1.

To sum up, the two cameras enjoy the same exact sensor sizing but not the same megapixels. You should anticipate the Sony a1 to give you more detail using its extra 32MP. Greater resolution can also let you crop images far more aggressively. The older M9 is going to be behind in sensor tech.
