Review Excerpt

  • Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size (at low ISOs); Fast x-sync speeds; Unique design is unconventional but comfortable and balanced.

  • Poor high ISO performance; Very sluggish buffer clearing; Poor low-light AF; No built-in flash; Very limited third-party RAW file support; Bundled Sigma Photo Pro RAW software is slow and buggy.

  • Read our Sigma dp2 Quattro Review

  • Rugged and waterproof camera body; RAW image capture; fast f/2.0 maximum aperture; fun shooting modes; fast AF speeds for its class.

  • Heavy noise reduction, even at base ISO; no continuous RAW image capture; underwhelming video performance.
