Review Excerpt

  • Compact DSLR camera body; Excellent image quality; Reliable single-shot autofocus; Good continuous JPEG shooting performance; New kit lens has improved AF; Great value at current prices.

  • SnapBridge is slow and limited; Poor continuous autofocus; No built-in Wi-Fi; Mediocre video features.

  • 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.
