Olympus E-1 vs Panasonic GH5S

Let's look a bit more closely at the Olympus E-1 versus Panasonic GH5S, one is a Pro DSLR and the latter is a Pro Mirrorless by competitors Olympus and Panasonic. There is a crucial difference between the image resolutions of the E-1 (5MP) and GH5S (10MP) but they feature the exact same sensor sizing (Four Thirds).

The E-1 was introduced 15 years earlier than the GH5S which is quite a serious gap as far as tech is concerned. The two cameras come with different body type with the Olympus E-1 being a Large SLR camera and the Panasonic GH5S being a SLR-style mirrorless camera.

Before diving through a in depth comparison, below is a quick overview of how the E-1 scores against the GH5S in relation to portability, imaging, features and an overall mark.

Here is a preview of the gallery images for Olympus E-1 and Panasonic Lumix DC-GH5S. The whole galleries are provided at Olympus E-1 Gallery and Panasonic GH5S Gallery.

Oftentimes, its difficult to imagine the contrast between sensor dimensions purely by looking at technical specs. The image underneath will offer you a stronger sense of the sensor sizing in the E-1 and GH5S.

As you can tell, the 2 cameras have got the exact same sensor measurements albeit different resolution. You should expect the Panasonic GH5S to resolve greater detail using its extra 5MP. Higher resolution will also enable you to crop pictures much more aggressively. The more aged E-1 is going to be disadvantaged when it comes to sensor tech.
