LCD viewfinder:


  • - Anti-aliasing filter simulator for when you have to decide between detail and moiré patterning
  • - Very fast AF from the nine centre points
  • - Excellent 100% pentaprism viewfinder


  • - Body design won’t appeal to everyone
  • - Centre control a bit fiddly to use
  • - Flucard needed for Wi-Fi transfer rather than having it built into camera
