Panasonic GH1 vs Sony A7S III

Here is a in depth overview of the Panasonic GH1 and Sony A7S III, one being a Advanced Mirrorless and the latter is a Pro Mirrorless by brands Panasonic and Sony. The sensor resolution of the GH1 (12MP) and the A7S III (12MP) is pretty well matched but the GH1 (Four Thirds) and A7S III (Full frame) boast totally different sensor size.

The GH1 was brought out 12 years before the A7S III and that is quite a big gap as far as tech is concerned. The two cameras feature the same body design (SLR-style mirrorless).

Before diving straight to a in depth comparison, here is a short introduction of how the GH1 grades vs the A7S III with regards to portability, imaging, features and an overall rating.

This is a preview of the gallery images for Panasonic Lumix DMC-GH1 and Sony Alpha A7S III. The entire galleries are available at Panasonic GH1 Gallery and Sony A7S III Gallery.

If you're intending to carry your camera frequently, you'll have to think about its weight and volume.

Oftentimes, its hard to visualise the gap between sensor sizing merely by checking a spec sheet. The graphic here might give you a more clear sense of the sensor sizing in the GH1 and A7S III.

As you can see, both of these cameras come with the identical MP albeit not the same sensor sizing. The GH1 contains the tinier sensor which will make achieving bokeh more challenging. The older GH1 is going to be disadvantaged with regard to sensor technology.
