This was my first wide angle lens after switching from DX to FX. I did a lot of research and got what was available. I use Nikon D-810 and love it. It's just that most of my lenses were DX format. I'm very happy with this lens and imagine it's on my camera most of the time. Test shots were crisp (slight blur at the edges at 120mm and zoomed in to check) and colourful. The VR worked well and is basically a great lens that I can take great pictures with. Also, 20-70mm is much larger! Even used. Another great lens for my setup.
