Olympus E-M10 III vs Sony H400

Lets look a little more closely at the Olympus E-M10 III vs Sony H400, one being a Entry-Level Mirrorless and the other is a Small Sensor Superzoom by brands Olympus and Sony. The image resolution of the E-M10 III (16MP) and the H400 (20MP) is fairly well matched but the E-M10 III (Four Thirds) and H400 (1/2.3") posses different sensor measurements.

Photography Glossary

The E-M10 III was released 3 years later than the H400 and that is quite a serious gap as far as tech is concerned. Each of these cameras have different body design with the Olympus E-M10 III being a SLR-style mirrorless camera and the Sony H400 being a SLR-like (bridge) camera.

Before getting straight to a step-by-step comparison, here is a quick synopsis of how the E-M10 III matches up against the H400 with respect to portability, imaging, features and an overall grade.

This is a sample of the gallery pictures for Olympus OM-D E-M10 Mark III and Sony Cyber-shot DSC-H400. The complete galleries are provided at Olympus E-M10 III Gallery and Sony H400 Gallery.

For anyone who is looking to lug around your camera often, you should consider its weight and dimensions.

In many cases, it's hard to visualize the contrast between sensor measurements purely by checking technical specs. The graphic below may give you a much better sense of the sensor sizes in the E-M10 III and H400.

As you can tell, each of the cameras provide different resolutions and different sensor measurements. The E-M10 III because of its larger sensor is going to make getting shallower DOF simpler and the Sony H400 will resolve extra detail as a result of its extra 4 Megapixels. Greater resolution will allow you to crop photos more aggressively. The more recent E-M10 III should have an advantage in sensor innovation.
