Review Excerpt

  • Superb image quality; Very high resolution; Surprisingly good high ISO performance; Fast autofocus; Compact, comfortable body with lots of customization potential; Bright, roomy and clear viewfinder; Tilting LCD display; Five-axis stabilization; Intuitive Wi-Fi / NFC connectivity

  • Movie button is poorly located; No touch screen; Not as fast to start up or shoot photos as a similarly-priced SLR; Rather slow buffer clearing; No built-in flash; Single card slot; Not weather-sealed to the same degree as some rivals

  • Excellent build and comfortable handling; Bright, roomy viewfinder and articulated LCD; Great image quality; Good performance for the class; In-camera stabilization, GPS and Wi-Fi; Incredibly feature-rich design.

  • Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
