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

Outstanding image quality; Excellent high ISOs; Fast AF performance with Eye-AF tracking; 10fps bursts at full-resolution; Improved ergonomics; Dual UHS-II card slots; Higher-res EVF.
Expensive; No 4Kp60; Buffer clearing could be faster; Menus are still frustrating; Touchscreen underutilized; No built-in flash.
