The GH4 was released 6 years before the A7R IV and that is quite a significant gap as far as tech is concerned. Both of these cameras have the same body design (SLR-style mirrorless).

Before getting into a thorough comparison, here is a short view of how the GH4 matches up versus the A7R IV when considering portability, imaging, features and an overall grade.

The following is a preview of the gallery photos for Panasonic Lumix DMC-GH4 and Sony Alpha A7R IV. The complete galleries are provided at Panasonic GH4 Gallery and Sony A7R IV Gallery.

In many cases, it is tough to visualise the difference between sensor measurements merely by reading through a spec sheet. The graphic here may offer you a more clear sense of the sensor dimensions in the GH4 and A7R IV.

Clearly, each of these cameras provide different megapixels and different sensor measurements. The GH4 due to its tinier sensor will make achieving bokeh more difficult and the Sony A7R IV will give extra detail as a result of its extra 45MP. Higher resolution will let you crop shots more aggressively. The older GH4 is going to be disadvantaged when it comes to sensor innovation.
