Couple weeks ago I got the new Nikon 70-200 f4 VR lens. Of course I mainly bought it for my D800, but I couldn't help testing it with V1. I had tested it one time before yesterday and noticed that it worked really well, but this weekend really blew my mind!
It's really great for shooting stationary subjects. AF-C doesn't work and in dim light focusing hunts, but when there is enough light the results are really good.
I also bought a J1 kit with 10mm pancake lens, because it was so cheap. Nice backup set for under 200€ :)
