Leica M8 vs Sony A7 III

Lets look a bit more closely at the Leica M8 vs Sony A7 III, both Pro Mirrorless digital cameras by manufacturers Leica and Sony. There is a noticeable difference between the sensor resolutions of the M8 (10MP) and A7 III (24MP) and the M8 (APS-H) and A7 III (Full frame) offer different sensor dimensions.

The M8 was revealed 11 years earlier than the A7 III and that is quite a sizable difference as far as tech is concerned. Both the cameras have different body design with the Leica M8 being a Rangefinder-style mirrorless camera and the Sony A7 III being a SLR-style mirrorless camera.

Before getting straight to a in-depth comparison, here is a simple summary of how the M8 matches up against the A7 III for portability, imaging, features and an overall grade.

If you are planning to lug around your camera often, you're going to have to consider its weight and dimensions. The Leica M8 offers outside dimensions of 139mm x 80mm x 37mm (5.5" x 3.1" x 1.5") accompanied by a weight of 591 grams (1.30 lbs) whilst the Sony A7 III has dimensions of 127mm x 96mm x 74mm (5.0" x 3.8" x 2.9") accompanied by a weight of 650 grams (1.43 lbs).

Do not forget, the weight of an ILC will change dependant on the lens you have chosen at that moment. Underneath is a front view measurements comparison of the M8 compared to the A7 III.

Considering size and weight, the portability score of the M8 and A7 III is 79 and 63 respectively.

Often, it's difficult to picture the gap between sensor measurements merely by checking technical specs. The visual underneath might give you a clearer sense of the sensor dimensions in the M8 and A7 III.

As you can tell, each of the cameras provide different resolutions and different sensor measurements. The M8 using its tinier sensor is going to make shooting shallower depth of field more challenging and the Sony A7 III will give more detail because of its extra 14MP. Higher resolution will also enable you to crop shots more aggressively. The older M8 is going to be disadvantaged in sensor tech.
