Leica M10 vs Olympus E-M1 III

Let's look closer at the Leica M10 vs Olympus E-M1 III, both Pro Mirrorless cameras by competitors Leica and Olympus. The sensor resolution of the M10 (24MP) and the E-M1 III (20MP) is relatively close but the M10 (Full frame) and E-M1 III (Four Thirds) enjoy different sensor dimensions.

Photography Glossary

The M10 was manufactured 4 years earlier than the E-M1 III and that is a fairly serious difference as far as camera tech is concerned. Both of the cameras come with different body type with the Leica M10 being a Rangefinder-style mirrorless camera and the Olympus E-M1 III being a SLR-style mirrorless camera.

Before delving straight into a more detailed comparison, below is a concise introduction of how the M10 grades versus the E-M1 III in terms of portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Leica M10 & Olympus OM-D E-M1 Mark III. The entire galleries are provided at Leica M10 Gallery & Olympus E-M1 III Gallery.

If you're aiming to lug around your camera regularly, you'll need to factor in its weight and measurements. The Leica M10 offers exterior measurements of 139mm x 80mm x 39mm (5.5" x 3.1" x 1.5") with a weight of 660 grams (1.46 lbs) whilst the Olympus E-M1 III has proportions of 134mm x 91mm x 69mm (5.3" x 3.6" x 2.7") with a weight of 580 grams (1.28 lbs).

Always remember, the weight of an ILC will change based on the lens you select at that time. The following is the front view over all size comparison of the M10 against the E-M1 III.

Considering size and weight, the portability score of the M10 and E-M1 III is 75 and 67 respectively.

In many cases, it's tough to imagine the gap in sensor measurements purely by researching specifications. The photograph here should give you a clearer sense of the sensor measurements in the M10 and E-M1 III.

To sum up, both cameras have got different megapixel count and different sensor measurements. The M10 because of its bigger sensor is going to make achieving shallower DOF simpler and the Leica M10 will result in greater detail due to its extra 4MP. Higher resolution will also allow you to crop shots much more aggressively. The older M10 will be behind in sensor innovation.
