New to panos, NN and this forum, so please be kind

Seriously thinking of upgrading my kit to a Nikon D600 and really like the look of the Nikon 16-35mm F4. This is quite a big/heavy lens, and wondered if anyone had any experience of using it for panos and if it will fit onto an NN4 ?

Won't do enough panos to justify fisheye or prime UW, hence the 16-35 which should work well for indoor (real estate) stills and landscape. Are there better alternatives that will do same job, at similar price point ?
