Leica M-Monochrom vs Sony A7 III

Here, we are analyzing the Leica M-Monochrom and Sony A7 III, both Pro Mirrorless digital cameras by manufacturers Leica and Sony. There exists a considerable gap between the sensor resolutions of the M-Monochrom (18MP) and A7 III (24MP) but both cameras offer the identical sensor measurements (Full frame).

The M-Monochrom was manufactured 6 years earlier than the A7 III which is quite a large difference as far as technology is concerned. Both of the cameras feature different body design with the Leica M-Monochrom being a Rangefinder-style mirrorless camera and the Sony A7 III being a SLR-style mirrorless camera.

Before we go into a complete comparison, here is a concise introduction of how the M-Monochrom grades against the A7 III in regards to portability, imaging, features and an overall score.

Typically, it's tough to visualize the difference between sensor sizes merely by reviewing a spec sheet. The image below will help offer you a more clear sense of the sensor measurements in the M-Monochrom and A7 III.

Clearly, both of the cameras feature the identical sensor size but different MP. You can expect to see the Sony A7 III to offer you greater detail due to its extra 6 Megapixels. Greater resolution can also make it easier to crop photos way more aggressively. The more aged M-Monochrom is going to be disadvantaged when it comes to sensor innovation.
