Review Excerpt

  • Highest resolution Canon APS-C camera yet; Improved dynamic range over T5i; Good high ISO performance for its class; Very fast autofocus; Built-in Wi-Fi with NFC; Touchscreen tilt/swivel LCD.

  • Shallow buffer depth with RAW files; Below average battery life; No Servo AF in Live View; No 60p video frame rate.

  • Very compact for a weather-sealed DSLR; Good ergonomics and great viewfinder; Excellent image quality; Decent performance for its class; Articulated screen is great for difficult compositions; Offers features not found in other Pentax DSLRs
