Lets look more closely at the Olympus E-300 and Panasonic GH5S, former being a Advanced DSLR while the latter is a Pro Mirrorless by companies Olympus and Panasonic. The resolution of the E-300 (8MP) and the GH5S (10MP) is pretty well matched and both cameras have the identical sensor sizing (Four Thirds).

The E-300 was brought out 14 years prior to the GH5S and that is quite a serious difference as far as technology is concerned. Each of these cameras feature different body design with the Olympus E-300 being a Mid-size SLR camera and the Panasonic GH5S being a SLR-style mirrorless camera.

Before diving right into a full comparison, here is a quick highlight of how the E-300 matches up versus the GH5S with regard to portability, imaging, features and an overall rating.

Normally, it can be hard to envision the gap between sensor sizing purely by reading through technical specs. The graphic below might give you a far better sense of the sensor sizing in the E-300 and GH5S.

As you can tell, both cameras feature the identical sensor size albeit not the same resolution. You can expect the Panasonic GH5S to give greater detail having its extra 2MP. Higher resolution will allow you to crop shots way more aggressively. The older E-300 is going to be disadvantaged in sensor tech.
