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

Improved image quality; Very good dynamic range & high ISO performance for a modern MFT sensor; Very fast AF; Excellent image stabilization; 4K video recording; Weather-sealed build quality.
Below average battery life; Small size can be awkward with long, heavy lenses; One SD card slot.
