The M9 was revealed 8 years prior to the A9 which is quite a large gap as far as technology is concerned. The two cameras come with different body type with the Leica M9 being a Rangefinder-style mirrorless camera and the Sony A9 being a SLR-style mirrorless camera.

Before getting through a more detailed comparison, below is a simple summation of how the M9 scores against the A9 for portability, imaging, features and an overall mark.

The following is a sample of the gallery pics for Leica M9 and Sony Alpha A9. The full galleries are viewable at Leica M9 Gallery and Sony A9 Gallery.

Typically, it can be tough to visualize the difference between sensor dimensions purely by reading through specs. The image below will offer you a more clear sense of the sensor measurements in the M9 and A9.

All in all, the 2 cameras posses the exact same sensor measurements but different MP. You should expect to see the Sony A9 to give more detail because of its extra 6MP. Greater resolution will make it easier to crop images somewhat more aggressively. The more aged M9 is going to be behind with regard to sensor innovation.
