Review Excerpt

  • Solid alloy body with true twin-dial design; Smaller, lighter, and cheaper than most direct competitors; Excellent image quality, even when compared to interchangeable-lens cameras; Numerous accessories expand upon its capabilities.

  • Fixed prime lens is not for everybody; Ergonomics could be better; Performance is spotty; Built-in flash is rather weak; Battery life is quite modest.
