Sony α9 Mirrorless Cameras (2017) vs Sony α7R Mirrorless Cameras (2017)

Analysis:

The Sony α9 (2017) is a great Mirrorless Camera for its $3498 asking price.

The Sony α7R III (2017), however, while a reasonable product for $2498, doesn't stack up against its competitors quite as well. If you're considering Mirrorless Cameras in the $2,800 range, you might want to check out some better options.

The Sony α9 (2017) was loved by reviewers at PCmag, a highly trusted source that performs reliable in-depth testing. It did great in its "The Best Full-Frame Cameras for 2020" roundup where it was named its "Best for Blackout-Free Shooting at 20fps", which, in itself, makes it a product worth considering.

Moving on to the Sony α7R III (2017): it was loved by reviewers at Expert Reviews and Digital Photography Review - two reliable sources that conduct objective in-depth testing. In fact, it was their "Best for pros" and "Mirrorless pick", respectively, pointing towards it being a Mirrorless Camera worth considering.

Out of the sources that tested and rated both of these Mirrorless Cameras, Digital Camera World preferred the Sony α9 (2017), whereas reviewers at DXOMARK liked the Sony α7R III (2017) better. TrustedReviews, Photography Blog, Techradar, camerajabber.com, and PCmag gave them identical review scores.

We also took a look at which sources liked these products best - the highest Sony α9 (2017) rating came from Expert Reviews, whereas the Sony α7R III (2017) most impressed reviewers at Techradar; 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 α9 (2017) and Sony α7R III (2017) managed averages of 9.5 and 9.5 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Sony α9 (2017) vs. Sony α7R III (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.
