Review Excerpt

  • Very small and comfortable form factor; Very good image quality for its class; New dual video record function; Quick autofocus and good dynamic range.

  • Lacks an EVF and external mode dial; No hot shoe; JPEG processing at higher ISOs not as good as some competing mid-level models.
