This device is used by my loved one - he is not a professional, just an amateur. Almost 2 years of experience. We always take it with us on trips. Its biggest problem is autofocus (as the prices for Mark 3 go down, we will buy it, because autofocus promises to be a bunny in the new version :)) In all other respects the device is super! Quality - 5 points! take a good optics and enjoy :)
