Canon S90 vs Olympus E-M10 IV

Below is a extended comparison of the Canon S90 and Olympus E-M10 IV, one being a Small Sensor Compact and the latter is a Entry-Level Mirrorless by rivals Canon and Olympus. There is a big difference between the sensor resolutions of the S90 (10MP) and E-M10 IV (20MP) and the S90 (1/1.7") and E-M10 IV (Four Thirds) have totally different sensor sizing.

The S90 was introduced 11 years before the E-M10 IV and that is quite a big gap as far as tech is concerned. Each of these cameras have different body design with the Canon S90 being a Compact camera and the Olympus E-M10 IV being a SLR-style mirrorless camera.

Before getting right into a thorough comparison, here is a quick view of how the S90 scores against the E-M10 IV in regards to portability, imaging, features and an overall grade.

Usually, it is very hard to visualise the difference between sensor measurements just by checking specifications. The graphic below should give you a much better sense of the sensor sizing in the S90 and E-M10 IV.

Plainly, each of these cameras provide different megapixels and different sensor measurements. The S90 using its tinier sensor will make shooting shallower DOF tougher and the Olympus E-M10 IV will resolve more detail using its extra 10MP. Higher resolution can also let you crop pictures more aggressively. The older S90 is going to be disadvantaged in sensor technology.
