Review Excerpt

  • Huge bang for the buck; Great image quality; Excellent high ISO performance; Fast autofocus; Good burst frame rate with deep buffer; Pentaprism viewfinder; Twin control dials; Articulated LCD; Comprehensive weather-sealing and freeze-proofing; Unbelievable wealth of rare to unique (yet very useful) features

  • Wi-Fi wireless communication is slow, clumsy and unintuitive; Video autofocus is prone to hunting or racking focus; Slow buffer clearing; Rather heavy for an entry-level DSLR; Autofocus and metering systems are a bit dated; Below average battery life

  • Read our Pentax K-70 Review

  • 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E-M1 II; Faces tough competition with image quality at this price point, especially at higher ISOs; EVF feels somewhat outdated; Expensive for a Micro Four Thirds camera.
