Review Excerpt

  • Appealing design; Good grip; Very good image quality; Fast autofocus; Built-in Level Gauge.

  • Small rear buttons; Below-average battery life; Weak flash; Orange and yellow can have greenish cast in JPEGs; Shutter-induced motion blur with 14-42mm X Vario kit lens.

  • Read our Panasonic GX1 Review

  • 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.
