The G2 was introduced 11 years earlier than the A7S III and that is a fairly significant gap as far as camera technology is concerned. Both of the cameras feature the same body design (SLR-style mirrorless).

Before getting straight to a full comparison, here is a simple overview of how the G2 matches up versus the A7S III with respect to portability, imaging, features and an overall rating.

Here is a preview of the gallery photos for Panasonic Lumix DMC-G2 and Sony Alpha A7S III. The whole galleries are provided at Panasonic G2 Gallery and Sony A7S III Gallery.

Normally, it's tough to visualise the contrast in sensor sizing purely by viewing specs. The photograph below may provide you a better sense of the sensor sizes in the G2 and A7S III.

As you can plainly see, each of these cameras feature the identical megapixel count albeit not the same sensor sizing. The G2 uses the smaller sensor which will make getting shallower DOF trickier. The older G2 will be behind when it comes to sensor technology.
