  1. I just received my lens and was quite impressed indeed. However, even though I put in the Non-CPU data on my NIKON D800 for this lens, I was a bit disappointed to see that as I stopped down the viewfinder became darker, which I understand is normal, but even with my older Ai Nikon Nikkor lenses, at least the aperture stays open until I click the shutter. Aperture priority metering does work as does the focus aid inside the viewfinder.
