The Olympus OM-D E-M10 Mark IV (2020) impressed reviewers from many highly trusted sources, including Tom's Guide, PCmag, Rtings, Digital Camera World, Wirecutter, and The Phoblographer. It performed great in their Mirrorless Camera roundups - it was named "A handsome, compact mirrorless camera that delivers great image quality" by Tom's Guide, "Best Micro Four Thirds Starter Camera Overall" by PCmag, and "Best Budget Mirrorless Camera For Street Photography" by Rtings. That's high praise from sources that conduct in-depth hands-on testing.

Moving on to the Olympus Pen E-PL9 (2018): 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 ePHOTOzine, Techradar, Photography Blog, Expert Reviews, camerajabber.com, Tom's Guide, and PCmag, enough for them to include them on those lists.
