Olympus E-M1 III vs Panasonic 3D1

On this page, we will be reviewing the Olympus E-M1 III vs Panasonic 3D1, one being a Pro Mirrorless and the latter is a Small Sensor Compact by rivals Olympus and Panasonic. There exists a significant gap between the sensor resolutions of the E-M1 III (20MP) and 3D1 (12MP) and the E-M1 III (Four Thirds) and 3D1 (1/2.3") have different sensor measurements.

The E-M1 III was revealed 8 years later than the 3D1 and that is quite a sizable gap as far as technology is concerned. Each of these cameras have different body design with the Olympus E-M1 III being a SLR-style mirrorless camera and the Panasonic 3D1 being a Compact camera.

Before we go straight to a complete comparison, here is a quick overview of how the E-M1 III scores versus the 3D1 in the way of portability, imaging, features and an overall rating.

Here is a preview of the gallery images for Olympus OM-D E-M1 Mark III and Panasonic Lumix DMC-3D1. The full galleries are viewable at Olympus E-M1 III Gallery and Panasonic 3D1 Gallery.

When you are aiming to carry your camera often, you will have to factor its weight and proportions. The Olympus E-M1 III provides outside measurements of 134mm x 91mm x 69mm (5.3" x 3.6" x 2.7") along with a weight of 580 grams (1.28 lbs) while the Panasonic 3D1 has measurements of 108mm x 58mm x 24mm (4.3" x 2.3" x 0.9") along with a weight of 193 grams (0.43 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary dependant on the lens you choose at the time. Following is a front view dimensions comparison of the E-M1 III and the 3D1.

Using dimensions and weight, the portability rating of the E-M1 III and 3D1 is 67 and 93 respectively.

Typically, it's hard to picture the contrast between sensor sizing purely by reading through technical specs. The photograph below may provide you a stronger sense of the sensor measurements in the E-M1 III and 3D1.

As you have seen, both of those cameras have different megapixel count and different sensor sizing. The E-M1 III having a bigger sensor is going to make getting shallow DOF easier and the Olympus E-M1 III will give you greater detail because of its extra 8 Megapixels. Higher resolution will enable you to crop photographs a bit more aggressively. The more modern E-M1 III should have a benefit when it comes to sensor innovation.
