So I'm already to the point where I have a Nikon D90 and the following three lenses:
Tamron sp af 28-75mm f/2.8 xr di
Sigma 18-200mm f3.5-6.3 dc
Nikkor 50mm f1.8 d
I'm a little confused though about something. I was thinking about possibly at some point upgrading to a Nikon D800. Which if any of these lenses will be compatible? From what I understand there are two types of mounts, DX and FX, and the D800 is an FX mount, but I can't seem to get a grasp of which kind my 3 current lenses are (i believe the Sigma is a DX though). And if they are DX, will they work and if there are any shortcomings.
I know this is something I probably should have known before hand, but I was never really thinking about getting another body so soon and I just was looking at compatibility with my D90 when buying.
Thanks for your help!
