My wife got herself a Nikon D700 and a 135mm F/2 VC lens on Monday. It’s a significant upgrade compared to my D200, because of the FX sensor, but I was mostly interested by the 135mm lens that she got. It’s a lens that enables you to control the focus and defocus, as Nikon puts it.
Basically, it lets you control the amount of bokeh in your photos. Anyway, it’s supposed to be a great portrait lens. I found it really nice to take photos of bikes.
