Review Excerpt

  • High quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.

  • Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.

  • 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.
