This field test report on the new Nikon 600mm f/4E FL ED VR lens is by Jess Lee (jessleephotos.com, westernphotographers.com, click on images for larger view):
I had been waiting for this lens to be announced for what seemed like a very long time. I needed a replacement for the Canon 600 I had sold after the first of the year. When the new lens was announced I expected a wait of 3 to 6 months before delivery but was pleasantly surprised when one of the first ones Nikons shipped showed up at Bozeman Camera with my name on the box. As luck would have it, I was in Cody Wyoming leading one of my Cowboy and Wild Horse workshops so I had to wait a few days before I could lay my hands on the lens but Saturday morning I was off on the 2 hour drive to Bozeman.
