Here, we will be comparing the Olympus E-M1 and Panasonic G9, both Pro Mirrorless cameras by companies Olympus and Panasonic. The resolution of the E-M1 (16MP) and the G9 (20MP) is pretty close and both cameras offer the identical sensor sizing (Four Thirds).

The E-M1 was manufactured 5 years prior to the G9 and that is a fairly big difference as far as camera tech is concerned. Both of these cameras feature the same body design (SLR-style mirrorless).

Before we go right into a thorough comparison, here is a concise synopsis of how the E-M1 scores vs the G9 when it comes to portability, imaging, features and an overall rating.

Oftentimes, it is very tough to imagine the contrast in sensor sizing merely by viewing specifications. The visual here should give you a better sense of the sensor dimensions in the E-M1 and G9.

Plainly, both of those cameras feature the identical sensor size albeit different MP. You can expect the Panasonic G9 to result in more detail due to its extra 4MP. Higher resolution will also let you crop shots way more aggressively. The older E-M1 will be disadvantaged in sensor innovation.
