Firstly I have just joined [NR] today so very new, therefore if this topic/question has been discussed before, I am sorry, please just point me in the right direction.
Okay, Question time:
I bought a D7100. My aim is to try and get some stunning Astro-photography images, of the stars, Milky Way and eventually the Northern Lights (when I can finally make time to travel). What I am hoping I can get help with is what Lenses I should buy. I currently have the Kit 18-105mm Nikon, and the 35mm 1.8f Nikon. I want to get a good quality wide angle Lens that would be suited for Astro-photography, but here is the twist, if possible I would like it to be compatible with FX cameras, as I plan to upgrade in the next couple years again. I am happy to consider 3rd Party Lenses, and I understand that technology waits for no man (or woman), so I can not be sure that a lens bought today would be compatible with a FX camera in the future, I can just hope :-)
Any thoughts on what Lenses to be considered and why would be greatly appreciated.
