Review Excerpt

  • Solid built and ergonomic, comfortable feel; Excellent f/1.8-2.8 5x optical zoom lens; Improved AF speed; Advanced photographic features, including PASM dial and RAW capture.

  • LCD screen no longer articulated; Optical viewfinder not very accurate and exhibits parallax; No WiFi or GPS.

  • 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.
