Olympus E-M10 III vs Sony T99

Its time to look much closer at the Olympus E-M10 III versus Sony T99, one being a Entry-Level Mirrorless and the latter is a Ultracompact by competitors Olympus and Sony. The sensor resolution of the E-M10 III (16MP) and the T99 (14MP) is pretty well matched but the E-M10 III (Four Thirds) and T99 (1/2.3") provide totally different sensor sizes.

The E-M10 III was unveiled 7 years later than the T99 and that is quite a large gap as far as tech is concerned. Both of these cameras have different body design with the Olympus E-M10 III being a SLR-style mirrorless camera and the Sony T99 being a Ultracompact camera.

Before going into a detailed comparison, here is a simple highlight of how the E-M10 III grades versus the T99 in terms of portability, imaging, features and an overall grade.

Following is a preview of the gallery images for Olympus OM-D E-M10 Mark III and Sony Cyber-shot DSC-T99. The full galleries are available at Olympus E-M10 III Gallery and Sony T99 Gallery.

For those who are planning to lug around your camera often, you will want to consider its weight and proportions. The Olympus E-M10 III features outer measurements of 122mm x 84mm x 50mm (4.8" x 3.3" x 2.0") along with a weight of 410 grams (0.90 lbs) and the Sony T99 has measurements of 93mm x 56mm x 17mm (3.7" x 2.2" x 0.7") and a weight of 121 grams (0.27 lbs).

Don't forget, the weight of an Interchangeable Lens Camera will differ depending on the lens you are employing at that time. Here is a front view dimensions comparison of the E-M10 III vs the T99.

Taking into consideration size and weight, the portability grade of the E-M10 III and T99 is 80 and 96 respectively.

In many cases, it's tough to visualise the gap between sensor measurements only by checking technical specs. The visual here should offer you a clearer sense of the sensor measurements in the E-M10 III and T99.

As you can tell, both cameras have different megapixel count and different sensor measurements. The E-M10 III using its bigger sensor will make achieving shallow depth of field simpler and the Olympus E-M10 III will give extra detail having an extra 2 Megapixels. Higher resolution will make it easier to crop shots a bit more aggressively. The more modern E-M10 III is going to have an advantage in sensor tech.
