Why do the differences between APS-C and full frame sensors matter?
I'm on my 3rd Nikon DX DSLR (D70, D80 and now D7000). I've enjoyed each camera and the advances brought by each model. However, I'm getting the itch to consider going to a more pro-level kit, and I'm wondering what the advantages are to a full-frame sensor? Obviously, the 1.5X crop factor would be gone, but I'd like to hear from others who've made the transition, and whether they believe it was worth it. I only have a few lenses (a kit, len, a prime and a 12-24 wide angle) so I'm not terribly vested in the DX format.
Thanks in advance!
