Sony α7 Mirrorless Cameras (2018) vs Panasonic Lumix G_ series Cameras (2017)

Analysis:

The Sony α7 III (2018) is an exemplary product and one of the very best Mirrorless Cameras at the $1,900 budget.

The Panasonic Lumix DC-G9 (2017), however, doesn't seem to have enough data available for us to be able to draw any meaningful conclusions.

Two highly trusted sources that perform well-thought-out in-depth testing consider the Sony α7 III (2018) to be a great product - it earned the "Best for Entry-Level Full Frame" title from PCmag and "Also great" from Wirecutter (NYTimes) in their respective Mirrorless Camera roundups, which is a good indication of it being a notable product.

Moving on to the Panasonic Lumix DC-G9 (2017): it was unable to reach the very top of any roundups from sources that conduct reliable and unbiased testing. Nonetheless, it still managed to impress reviewers from a number of such sites, like Expert Reviews, camerajabber.com, Digital Camera World, Techradar, TrustedReviews, Digital Photography Review, and Wirecutter (NYTimes), enough for them to include them on those lists.

Out of the sources that tested and rated both of these Mirrorless Cameras, Techradar and Digital Photography Review preferred the Sony α7 III (2018), whereas reviewers at Digitaltrends liked the Panasonic Lumix DC-G9 (2017) better. Digital Camera World and TrustedReviews gave them identical review scores.

We also took a look at which sources liked these products best - the highest Sony α7 III (2018) rating came from PCmag, whereas the Panasonic Lumix DC-G9 (2017) most impressed reviewers at camerajabber.com; they earned scores of 10 and 10, respectively.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Mirrorless Cameras on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Mirrorless Cameras being 7.9 out of 10, whereas the Sony α7 III (2018) and Panasonic Lumix DC-G9 (2017) managed averages of 9.3 and 9.4 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Sony α7 III (2018) vs. Panasonic Lumix DC-G9 (2017) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
