Leica M9-P vs Olympus E-M1 III

Its time to take a closer look at the Leica M9-P versus Olympus E-M1 III, both Pro Mirrorless digital cameras by brands Leica and Olympus. The resolution of the M9-P (18MP) and the E-M1 III (20MP) is relatively similar but the M9-P (Full frame) and E-M1 III (Four Thirds) posses totally different sensor sizes.

The M9-P was released 9 years before the E-M1 III and that is quite a significant gap as far as technology is concerned. Both of these cameras feature different body design with the Leica M9-P being a Rangefinder-style mirrorless camera and the Olympus E-M1 III being a SLR-style mirrorless camera.

Before going into a full comparison, here is a simple summation of how the M9-P grades versus the E-M1 III when considering portability, imaging, features and an overall rating.

Following is a preview of the gallery photos for Leica M9-P and Olympus OM-D E-M1 Mark III. The complete galleries are available at Leica M9-P Gallery and Olympus E-M1 III Gallery.

When you are planning to carry your camera regularly, you should consider its weight and proportions.

More often than not, its hard to see the contrast between sensor sizing only by reading specifications. The graphic below will help offer you a better sense of the sensor sizes in the M9-P and E-M1 III.

Plainly, the 2 cameras feature different megapixels and different sensor sizing. The M9-P due to its bigger sensor will make achieving shallow DOF less difficult and the Olympus E-M1 III will offer you more detail as a result of its extra 2MP. Higher resolution can also help you crop photographs way more aggressively. The older M9-P is going to be disadvantaged when it comes to sensor tech.
