Olympus E-M1 III vs Olympus TG-810

Following is a thorough assessment of the Olympus E-M1 III vs Olympus TG-810, one is a Pro Mirrorless and the other is a Waterproof and they are both designed by Olympus. There exists a big gap among the sensor resolutions of the E-M1 III (20MP) and TG-810 (14MP) and the E-M1 III (Four Thirds) and TG-810 (1/2.3") have totally different sensor size.

The E-M1 III was unveiled 8 years after the TG-810 which is a fairly big gap as far as camera technology is concerned. Each of the cameras have different body design with the Olympus E-M1 III being a SLR-style mirrorless camera and the Olympus TG-810 being a Compact camera.

Before delving straight to a full comparison, here is a quick overview of how the E-M1 III matches up versus the TG-810 in terms of portability, imaging, features and an overall score.

Below is a sample of the gallery pics for Olympus OM-D E-M1 Mark III and Olympus TG-810. The full galleries are provided at Olympus E-M1 III Gallery and Olympus TG-810 Gallery.

For those who are looking to carry around your camera frequently, you have to factor its weight and volume. The Olympus E-M1 III comes with outside measurements of 134mm x 91mm x 69mm (5.3" x 3.6" x 2.7") with a weight of 580 grams (1.28 lbs) and the Olympus TG-810 has sizing of 100mm x 65mm x 26mm (3.9" x 2.6" x 1.0") accompanied by a weight of 215 grams (0.47 lbs).

Take into account, the weight of an Interchangeable Lens Camera will vary depending on the lens you have attached during that time. Here is a front view dimensions comparison of the E-M1 III compared to the TG-810.

Taking into consideration dimensions and weight, the portability score of the E-M1 III and TG-810 is 67 and 92 respectively.

Typically, it can be hard to see the difference in sensor sizes purely by looking through technical specs. The picture below will offer you a clearer sense of the sensor measurements in the E-M1 III and TG-810.

As you have seen, both cameras provide different megapixels and different sensor sizes. The E-M1 III using its larger sensor will make getting shallower DOF easier and the Olympus E-M1 III will render greater detail having an extra 6MP. Greater resolution will enable you to crop pics more aggressively. The younger E-M1 III is going to have a benefit when it comes to sensor innovation.
