Review Excerpt

  • The most compact APS-C camera on the market; Bright, sharp 28mm f/2.8 prime lens with almost no distortion; Excellent image quality; Extremely customizable; Fast autofocus; Strong built-in flash plus hot shoe.

  • Fixed prime lens is not for everybody; Crowded and small controls; Burst performance is limited; Muted colors and cool white balance; Has issues with moire and false color.

  • Read our Ricoh GR Review

  • Great image quality especially from RAW files; Excellent dynamic range for a Four Thirds sensor; Very good high ISO performance; Realistic colors and excellent hue accuracy; Built-in Wi-Fi with remote control and sharing features; Improved HD video; Lightweight and very portable; Built-in pop-up flash; Minimal EVF lag time.

  • Contrast-Detect AF struggles with small and low-contrast subjects; Mediocre battery life; No external microphone or headphone jack; Mediocre burst speed with continuous AF; No weather sealing; Heavy-handed high ISO noise reduction.
