Review Excerpt

  • Pocket-friendly design; Unbelievably fast burst capture; Generous buffer depth, even for raw; Fast and confident autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; High-quality 4K video with uncompressed HDMI out; Super-fast High Frame Rate video

  • Very pricey for a compact camera; Still no touch screen; Slow buffer clearing; JPEGs can look over-processed at higher ISOs; Lens doesn't offer much telephoto reach; Battery life is very modest; 4K movies are limited to five minute clips

  • Read our Sony RX100 V Review

  • 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.
