Here is a in depth review of the Leica M9 and Sony A9 II, both Pro Mirrorless digital cameras by companies Leica and Sony. There exists a considerable gap between the resolutions of the M9 (18MP) and A9 II (24MP) but they possess the exact same sensor sizes (Full frame).

The M9 was released 11 years before the A9 II and that is quite a large difference as far as technology is concerned. Both of the cameras come with different body type with the Leica M9 being a Rangefinder-style mirrorless camera and the Sony A9 II being a SLR-style mirrorless camera.

Before delving straight into a full comparison, below is a short summary of how the M9 matches up versus the A9 II with regard to portability, imaging, features and an overall rating.

This is a sample of the gallery pics for Leica M9 & Sony Alpha A9 Mark II. The complete galleries are provided at Leica M9 Gallery & Sony A9 II Gallery.

Typically, its difficult to visualise the gap between sensor sizing purely by looking at specs. The visual here should offer you a far better sense of the sensor dimensions in the M9 and A9 II.

All in all, both of these cameras posses the exact same sensor measurements but not the same resolution. You can expect to see the Sony A9 II to give greater detail as a result of its extra 6MP. Greater resolution can also let you crop photos somewhat more aggressively. The older M9 is going to be behind when it comes to sensor technology.
