Sony α7R Mirrorless Cameras (2019) vs Olympus OM-D E-M10 Cameras (2017)

Analysis:

The Sony α7R IV (2019) and Olympus OM-D E-M10 Mark III (2017) are both excellent choices at their respective budgets. The Sony α7R IV (2019) is among the very best Mirrorless Cameras for $2998 and the Olympus OM-D E-M10 Mark III (2017) is exemplary at $449. Depending on how much you're willing to spend, you can't go wrong with either option.

The Sony α7R IV (2019) impressed reviewers from many sources that have a history of conducting objective testing, such as Digital Photography Review, PCmag, shotkit.com, Techradar, Digital Camera World, and camerajabber.com. It performed really well in their roundups - it was awarded the"Top Pick" title from Digital Photography Review, "Best for Uncompromised Resolution and Speed" from PCmag, and "BEST IMAGE QUALITY" from shotkit.com. That's high praise coming from numerous reliable sources.

Moving on to the Olympus OM-D E-M10 Mark III (2017): it was well-received by reviewers from numerous sources that perform their own objective hands-on testing, including Wirecutter (NYTimes), Expert Reviews, Techradar, Digital Camera World, shotkit.com, Digital Photography Review, and camerajabber.com. It did great in their roundups - it was named "Top Pick" by Wirecutter (NYTimes), "Best for long zoom shots" by Expert Reviews, and "This travel-friendly mirrorless all-rounder now offers superb value" by Techradar. That alone points toward it being worthy of consideration.

Out of the sources that tested and rated both of these Mirrorless Cameras, PCmag, Digital Photography Review, and TrustedReviews preferred the Sony α7R IV (2019), whereas reviewers at Digital Camera World liked the Olympus OM-D E-M10 Mark III (2017) better. Techradar and Pocket-lint gave them identical review scores.

We also took a look at which sources liked these products best - the highest Sony α7R IV (2019) rating came from PCmag, whereas the Olympus OM-D E-M10 Mark III (2017) most impressed reviewers at Digital Camera World; 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 α7R IV (2019) and Olympus OM-D E-M10 Mark III (2017) managed averages of 9.0 and 8.4 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Sony α7R IV (2019) vs. Olympus OM-D E-M10 Mark 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.
