Review Excerpt

  • Terrific overall image quality for a 20MP 4/3" sensor; Very good high ISO performance this sensor size; Very impressive & improved AF performance; Extremely fast, responsive overall performance; New Intelligent Subject Detection AF feature works well; More video features; Outstanding IBIS.

  • Image quality not improved from (updated) E-M1 II; Faces tough competition with image quality at this price point, especially at higher ISOs; EVF feels somewhat outdated; Expensive for a Micro Four Thirds camera.
