Leica M10 vs Olympus E-P3

Lets take a closer look at the Leica M10 vs Olympus E-P3, former is a Pro Mirrorless while the latter is a Entry-Level Mirrorless by brands Leica and Olympus. There exists a considerable gap between the sensor resolutions of the M10 (24MP) and E-P3 (12MP) and the M10 (Full frame) and E-P3 (Four Thirds) feature different sensor sizes.

The M10 was unveiled 5 years after the E-P3 which is quite a large difference as far as technology is concerned. Both the cameras offer the identical body type (Rangefinder-style mirrorless).

Before we go through a in-depth comparison, below is a simple overview of how the M10 grades vs the E-P3 with regard to portability, imaging, features and an overall mark.

Following is a preview of the gallery images for Leica M10 & Olympus PEN E-P3. The full galleries are available at Leica M10 Gallery & Olympus E-P3 Gallery.

For anybody who is intending to travel with your camera frequently, you will need to factor its weight and volume. The Leica M10 has outer dimensions of 139mm x 80mm x 39mm (5.5" x 3.1" x 1.5") accompanied by a weight of 660 grams (1.46 lbs) while the Olympus E-P3 has sizing of 122mm x 69mm x 34mm (4.8" x 2.7" x 1.3") with a weight of 369 grams (0.81 lbs).

Take into consideration, the weight of an ILC will differ dependant on the lens you have attached at that moment. Here is the front view physical size comparison of the M10 against the E-P3.

Factoring in dimensions and weight, the portability score of the M10 and E-P3 is 75 and 86 respectively.

Typically, it is very difficult to imagine the difference between sensor dimensions purely by reading specifications. The pic below may give you a better sense of the sensor dimensions in the M10 and E-P3.

Plainly, the two cameras offer different megapixels and different sensor dimensions. The M10 using its bigger sensor is going to make getting shallow DOF less difficult and the Leica M10 will deliver more detail having an extra 12 Megapixels. Higher resolution can also make it easier to crop pictures a little more aggressively. The newer M10 provides an advantage in sensor innovation.
