Olympus E-M10 III vs Olympus TG-850 iHS

Here is a in depth overview of the Olympus E-M10 III versus Olympus TG-850 iHS, former being a Entry-Level Mirrorless while the other is a Waterproof and both of them are built by Olympus. The image resolution of the E-M10 III (16MP) and the TG-850 iHS (16MP) is very well matched but the E-M10 III (Four Thirds) and TG-850 iHS (1/2.3") offer totally different sensor dimensions.

The E-M10 III was revealed 3 years later than the TG-850 iHS and that is quite a large difference as far as technology is concerned. Each of these cameras have different body design with the Olympus E-M10 III being a SLR-style mirrorless camera and the Olympus TG-850 iHS being a Compact camera.

Before we go into a more detailed comparison, here is a concise summary of how the E-M10 III grades versus the TG-850 iHS with regard to portability, imaging, features and an overall rating.

The following is a sample of the gallery pics for Olympus OM-D E-M10 Mark III & Olympus Stylus Tough TG-850 iHS. The full galleries are available at Olympus E-M10 III Gallery & Olympus TG-850 iHS Gallery.

Quite often, it is very difficult to visualise the gap between sensor sizing merely by reading through specifications. The photograph underneath should give you a better sense of the sensor sizes in the E-M10 III and TG-850 iHS.

To sum up, both of the cameras provide the same megapixels but not the same sensor sizing. The E-M10 III includes the larger sensor which should make obtaining shallow DOF simpler. The fresher E-M10 III will have an advantage in sensor technology.
