Anybody in Yorkshire, UK with d810/d500/d750 willing to meet with me so I can try out body with my Nikon lens?

Hello everybody,I'd like to know if there is anybody in Yorkshire, UK with d810/d500/d750 body willing to meet with me so I can try out my Nikon lens with it? Currently I own A7 with 55 1.8 but I am seriously thinking about switching to Nikon/Canon/Fuji as I think these systems will suit my needs better. I own old Sigma 28-70 2.8 screwdrive-type lens and I would love to try it out on some high-end Nikon bodies.Best regards. via /r/photography http://ift.tt/2tSTNvW
