Very sound reasoning ShakenBake. I admire your resolve in avoiding NAS.
My history in photography is similar to yours. My first camera was at age 7, I believe it used 110 size film (remember flash cubes?).
I have lusted after an Fx Nikon since the D1. I avoided Dx lenses even though Nikon and their dealers insisted, until about a year and a half ago, that they would NEVER make a full frame DSLR. The only Dx lens I own is a Tokina 12-24.
Anyways, being a D200 shooter and having avoided NAS for the D300/D3 generation, the D700 is irresistable. Wide at 24mm, 35mm format depth of field, low light capabilities, and D200/D300 size were enough to overwhelm any resistance to NAS I thought I had. I'm first on the list at my local dealer (paid a $660 deposit for the priveledge) and am like a kid at Christmas waiting for the arrival of my new toy.
Will I take better photos? Probably not. The D200 is an amazing camera that produces excellent photos when used within its limits.
I have, however, hit the limits of what I can do with the D200 many times and look forward to the capabilities of my new D700. If not better pictures then at least I can look forward to more opportunities for getting the shot I want.
Thank you Nikon.
