The E-M1 III was manufactured 10 years later than the TX7 and that is quite a significant gap as far as tech is concerned. Each of the cameras come with different body type with the Olympus E-M1 III being a SLR-style mirrorless camera and the Sony TX7 being a Ultracompact camera.

Before going straight into a more detailed comparison, below is a short synopsis of how the E-M1 III grades against the TX7 in the way of portability, imaging, features and an overall grade.

Following is a sample of the gallery pictures for Olympus OM-D E-M1 Mark III and Sony Cyber-shot DSC-TX7. The entire galleries are viewable at Olympus E-M1 III Gallery and Sony TX7 Gallery.

When you are looking to lug around your camera, you'll have to factor its weight and volume.

Generally, it is very hard to imagine the contrast between sensor measurements purely by reading through technical specs. The graphic here will provide you a far better sense of the sensor measurements in the E-M1 III and TX7.

As you can tell, both of those cameras have got different megapixels and different sensor measurements. The E-M1 III due to its larger sensor is going to make getting bokeh less difficult and the Olympus E-M1 III will give extra detail due to its extra 10 Megapixels. Greater resolution will also allow you to crop pics much more aggressively. The fresher E-M1 III should have an edge in sensor tech.
