That's a Nikon new release in late 2018, prime lens. It is not f2.8, but fast enough for sunny daylight weather. Wildlife approved. Supposedly released in limited supply. Much like the D850 was, when it first came out. In due time, supply will catch up to demand. The lens is priced at about $3600. It looks like a great lens. Enjoy it. I think it will be worth it.
Mas: Look at the title of the OP, or maybe you were referring to the 400mm then ignore.
